  abstract =     "'Data' is defined as being digital matter having
                 utility. A 'data descriptive language' is a manner of
                 description of how such digital matter can be
                 transformed into a more useful form. Data descriptive
                 languages are characterized as being iconographic,
                 algorithmic, or a mixture of both. File structures are
                 held to be merely a special case of data. An
                 algorithmic data description is always possible, by
                 definition, since otherwise the digital matter under
                 consideration is not 'data'. In a trivial sense, such
                 languages as COBOL or FORTRAN are found to be
                 completely general data descriptive languages, although
                 they are otherwise quite unsuitable because they are so
                 poorly fitted to the descriptive task. A good data
                 descriptive language should be congenial to use,
                 general, transformable, and independent of supporting
                 hardware or software. The value of small one-man
                 projects for the creation of data languages is
                 suggested.",

                 virtual information in data base systems. Virtual
                 information is any fact which does not physically exist
                 in the data base, but is nonetheless accessible through
                 combinations of algorithms and other data. Physically
                 recorded information is only one of a number of ways to
                 obtain information from a data-base system. Viewing an
                 information system as a collection of functions shows
                 that pure data and pure algorithm from the endpoints of
                 a spectrum of ways function values can be realized,
                 with the middle range being various types of virtual
                 information. Several classes of virtual information are
                 identified, and their usefulness is examined to show
                 the appropriateness of the concept in a data-base
                 system. Finally, the model is evaluated in light of the
                 implications of virtual information for inference and
                 automatic restructuring within a data base.",

                 covers a number of sensitive variables. The only
                 feasible way to evaluate the effects of varying
                 combinations of values for these variables, is via
                 simulation. Many of the drawbacks of simulation have
                 been alleviated by the creation of a comprehensive,
                 validated model of IMS, which feeds mostly on
                 pre-existing data. This model allows the evaluation of
                 many alternatives, including data base design. A case

                 data structures used inside programs (instead of just
                 those in an external data base) to be described at
                 multiple conceptual levels by a separate definition.
                 This approach brings to programmers the benefits of
                 data independence and also allows structured
                 programming to have its hitherto unrealized full effect
                 on data.",

  abstract =     "A relational data base is herein defined as a
                 collection of normalized relations (relations in first
                 normal form) and a collection of domains. A normalized
                 relation may be viewed as a table, wherein each row of
                 the table corresponds to a tuple of the relation, and
                 the entries in a given column belong to the set of
                 values constituting the domain underlying that column.
                 The domains of a data base have an abstract existence
                 apart from the data base relations. The data base also
                 includes various types of semantic integrity rules,
                 which specify additional properties of the data in the
                 data base. One such type of semantic integrity rule is
                 the domain definition. A domain definition includes the
                 precise description of the set of values (objects)
                 constituting the domain. In a normalized data base, all
                 domains are sets of atomic data values. A domain
                 definition also includes a specification of the
                 ordering on the values in a domain, for comparability
                 purposes. In addition, a domain definition contains a
                 specification of the action that is to occur if an
                 attempt is made to violate the restriction that every
                 entry in each column of a relation must be from the
                 underlying domain of that column. A nonprocedural
                 language permitting the high level expression of domain
                 definitions is defined. Language details and examples
                 are presented, and the syntax and informal semantics of
                 the domain definition language are given. This approach
                 to domain definition is analyzed in terms of its impact
                 on other aspects of data base semantic integrity. The
                 relationship with the data base system in general is
                 outlined. An analysis of intradomain and interdomain
                 comparability is included. An introduction to relevant
                 implementation issues is also presented. Emphasis is
                 placed on a general approach to implementation and
                 implementation techniques, rather than on a specific

                 implementation. The user of an abstract data type only
                 concerns himself with the behavioral semantics of the
                 type: what meaningful operations can be applied to
                 objects of the type; the internal representation and
                 structure of the type is unknown to him. In this way,
                 irrelevant detail is suppressed and meaningfulness of
                 programs enhanced. What application does this concept
                 have to the area of data bases? There are some obvious
                 similarities between the principle of abstraction and
                 the concept of data independence of data bases [2].
                 Data independence means that application programs that
                 utilize a data base do not need to know either the
                 physical or the structural organization of the data
                 base, but can relate to it purely on a logical plane.
                 As with data abstractions, the goal is clarity and
                 modifiability of programs, resulting from concentration
                 on semantics rather than representation.",

                 languages need ``data abstraction facilities,'' and to
                 assert that the provision of such facilities would
                 provide conceptual and practical advantages in the
                 domain of data structures akin to the advantages
                 provided by procedures in the domain of computational
                 structures. This note explores some of the implications
                 of this metaphor, without attempting to make it
                 precise. I shall use the term capsule to refer to the
                 data analog of procedure. [Those who are familiar with
                 the SIMULA class, the CLU cluster, or the ALPHARD form,
                 may use any of these as an approximation to capsule; I
                 use a neutral term to avoid implying the details of any
                 particular language.] First, what are the advantages
                 provided by procedures (subroutines, functions,
                 macros)? I can think of at least eight (highly
                 interrelated) categories: (1) avoidance of repetition,
                 (2) modular program structure, (3) a basis for structured
                 programming, (4) conceptual units for understanding and
                 reasoning about programs, (5) clearly defined interfaces
                 that may be precisely specified, (6) units of
                 maintenance and improvement, (7) a language extension
                 mechanism, and (8) units for separate compilation. Let
                 us consider each of these in turn.",

                 developed and verified without regard to how the

                 its proof. In [4], the notion of a scheme as a model

                 a module which takes normal values plus types as formal

                 parameters yields a scheme instance which is a data

                 parameter. An instance of this scheme, for example, AVL

                 structured in a way which supports a users abstractions
                 about the real-world system. The ``relation'' data type
                 is introduced as a structuring primitive for relational
                 data bases The relation data type has similar
                 abstraction properties to the ``record'' data type of
                 PASCAL. A data base defined via relation data types is
                 structured as a hierarchy of n-ary relations. It is
                 shown that the consistency of this hierarchic structure
                 can be preserved during update operations by two simple
                 rules. A top-down methodology for data base design with
                 relation data types is developed. This methodology
                 minimizes the number of details with which a designer
                 must contend at one time. In particular, the

                 concerning abstract structure from decisions concerning
                 key identification. The separation simplifies both

                 adds to the complexity of stating algorithms by forcing
                 one to conceptualize data representations in which
                 storage addressing is made manifest. In addition, the
                 use of pointer variables allows one to refer to a
                 common data object by a multiplicity of names, a
                 phenomenon we call the alias variable problem, Alias
                 variables make the verification of program behavior
                 substantially more difficult, and frustrate the goals
                 of modular decomposition. In this paper, we consider
                 alternatives to the use of pointer variables in
                 programming. One of these alternatives is the inclusion
                 of a class of data abstractions based on recursively
                 defined data types. The representational power of the
                 proposed data types is characterized formally, and some
                 issues of implementation and efficiency of programs are
                 discussed.",

                 light of what is being learned about construction of
                 reliable software, pointers are desirable in high level
                 programming languages. One side [Hoa73, Hoa75]
                 maintains that (1) Pointers are like the goto in that
                 they are an invitation to create spaghetti in one's
                 program [Hoa75]. (2) In some languages, e.g., PL/1
                 [Wlk71], the use of pointers can lead to serious type
                 violations, for example, the compiler believes that a
                 given pointer will be pointing to an integer when in
                 fact, it will be pointing to a real. (3) The
                 indiscriminate use of pointers may confound the
                 attempts of hardware pipelining and use of cache memory
                 to speed up computations [Hoa73, Hoa75]. (4) A pointer
                 may be left dangling, that is, a pointer may point to a
                 variable or other datum which has been deallocated
                 [Bry71, CDMPS73, Bry74].",

                 types should be allowed and so forth. The current
                 notion that a data type is a set of values together
                 with basic operations on that set leads us to conclude
                 that formal parameter types need not be so explicitly

                 $\alpha_1, \ldots{}, \alpha_n$ being performed on X
                 within a procedure, one should be able to supply, as

                 Recently this approach under the name, structured
                 programming, has been used in a pragmatic way to
                 simplify the structure of procedural programs. The
                 notion has also been used in the data base area -
                 notable early papers include those of Madnick (1) and
                 Meltzer (1). In these early papers, level structures
                 (for example, involving logical and physical levels)
                 were also relatively pragmatic creations. One new
                 aspect of the DIAM I architecture (3) was that it
                 defined a detailed, relatively formal basis for four
                 levels of abstraction and the mappings between these
                 levels. Each level had a small set of primitive
                 generalized building blocks, each with its own small
                 permanent set of parameters. By specifying values for

  abstract =     "What information about data base technology does a
                 manager need to make prudent decisions about using this
                 new technology? To provide this information the
                 National Bureau of Standards and the Association for
                 Computing Machinery established a workshop of
                 approximately 80 experts in five major subject areas.
                 The five subject areas were auditing, evolving
                 technology, government regulations, standards, and user
                 experience. Each area prepared a report contained in
                 these proceedings. The proceedings provide guidance of
                 steps managers should follow to prepare themselves and
                 their organization for the installation of data base
                 management concepts. The auditing working panel noted
                 the increased vulnerability of organizations who
                 integrate their formerly dispersed and redundant files
                 into a data base and suggest actions to address this
                 risk. The technology report noted several promising
                 parallel developments but concluded that the future
                 would see evolving, rather than revolutionary data base
                 progress. Government regulations, particularly the
                 drive for individual privacy rights, were seen to play
                 an important role in determining data base directions
                 and the panel's guidance on cost impact suggest that
                 organizations would experience reduced costs with data
                 base technology. Standards pervaded all issues and were
                 found necessary in several sub-areas of data base
                 technology but the panel saw no immediate likelihood of
                 national data base standards. The user experience
                 working panel noted that data base systems had impacted
                 their organizations to the extent of reconsidering
                 existing data flows, areas of responsibilities, and
                 procedures.",

                 problem in the information processing sciences --- that
                 of searching very large (5-50 billion characters) data
                 bases of unstructured free-text for random queries
                 within a reasonable time and at an affordable price.
                 The need by information specialists and knowledge
                 workers for large, fast low-cost text and document
                 retrieval systems is growing rapidly. Conventional
                 approaches to the problem have usually depended upon
                 expensive, general purpose computers, upon special
                 pre-preprocessing of the textual data (e.g. file
                 inverting, indexing, abstracting, etc.), and upon
                 elaborate, costly software. The resulting retrieval
                 systems often cost hundreds of dollars per query and
                 the full scanning of an uninverted, unstructured
                 billion byte textual data base could take hours of
                 computer services. However, in spite of these
                 restrictions, such full text search systems have proved
                 useful and even indispensible for many applications.

                 electronics, natural language query systems, etc.),
                 have made i t practical to build special purpose,
                 low-cost text retrieval systems. Such a system has been
                 built, tested, and is now in a production stage. The
                 system called the Associative File Processor (AFP),
                 utilizes a conventional minicomputer (DEC's PDP-11/45)
                 for control, off-the-shelf high density disks for
                 storage, a special purpose parallel search module as a
                 text term detector, and query and retrieval software.
                 The AFP is currently being field tested at two sites.
                 Full text, parallel searches on un-preprocessed textual
                 data bases are being performed at the effective
                 matching rates of 4 billion bytes per second (8K byte
                 key memory times 500 Kbyte/second data stream).
                 Estimated costs are 10 to 25 cents per query for a one
                 billion byte data base. The costs per query and the
                 time for searching increase in a linear fashion as data
                 base increases. A basic architecture for the AFP is
                 described and an implemented version is discussed. A
                 more powerful term detector module is also under
                 development. This system is designed around a finite
                 state automaton algorithm.",

                 recognized that the parallel processing capabilities of

                 database management functions traditionally carried out
                 by software has been apparent to data-base designers
                 for sometime now. Firstly, database management software
                 has grown in complexity and size over the years. This
                 growth is prompted by the increase in user
                 requirements, by the formulation of sophisticated
                 models and by the change in data processing mode from
                 an off-line, batched, single user environment to an
                 on-line, concurrent and multi-user environment. Large
                 and complex software systems tend to be failure-prone.
                 Further-more, practical verification methods for
                 software systems are still not in sight. On the other
                 hand, methods for verifying hardware functionality,
                 design and production have long been available.

                 large and complex computers viable. By incorporating
                 basic database management functions into hardware, not
                 only can we provide more reliable basic functions, but
                 we can also improve the software reliability since the

                 ``backend'' and ``data management machine'' have been
                 applied to such devices. Examination of the literature
                 reveals a broad cross section of host to backend
                 functional distribution and interconnection
                 methodology. This discussion represents an attempt to
                 examine and classify several of these backend data base

  abstract =     "Memory management, database management, and message
                 processing have in the past been defined in a
                 relatively narrow way. With memory management the
                 problem was to obtain cost effective use of real
                 memory. Given a multiprogrammed environment, virtual
                 memory systems allowed more effective use of expensive
                 real memory. Memory management has become even more
                 important with the development of very large and
                 complex memory hierarchies. Database management systems
                 were developed to allow the more effective use,
                 sharing, and control of data resources - objectives
                 which operating systems had previously provided for
                 hardware resources. The driving force behind message
                 processing has been the increased use of data
                 communications and computer networks. This paper will
                 consider the basis of the overlap in these areas, their
                 common data management functions. Data management, as
                 defined in this paper, includes the locating, routing,
                 moving, and translating of data resources and the
                 locating, reserving, and releasing of physical
                 resources, i.e., primary and secondary storage. The
                 analysis performed in this paper is essential because
                 of trends in computer architecture discussed below.
                 Early hardware was designed for general purpose
                 environments with software used to tailor it to
                 specific applications. However, according to Gagliardi9
                 future systems will consist of a set of subsystems,
                 including a storage subsystem at the core surrounded by
                 computational, spooling, and communications subsystems.
                 The computational subsystem is the traditional ``number
                 cruncher'' part of the system. The spooling subsystem
                 provides the I/O interface between the system and the
                 outside world. The communications subsystem links the
                 various subsystems together and provides an interface
                 to the rest of the network if the system is part of a
                 larger distributed system. The storage subsystem
                 consists of all the system's storage resources and
                 their control processes. It controls all levels of the
                 system memory and storage hierarchy. The storage
                 subsystem controls the allocation of the physical
                 storage resources and the movement of the data
                 resources through the system. Depending on how these
                 resources are used, they may be non-conserved or
                 conserved, and if conserved, either serially reusable
                 or sharable. Physical and data resources may be
                 located, and if necessary reserved, independently or
                 jointly.",

                 amount of hardware present in the system. These goals
                 are accomplished with a simple hardware arrangement
                 within a one-dimensional cellular storage system called
                 INDY. The INDY backend kernel is intended as a powerful
                 tool for implementing all data models. The INDY
                 cellular storage array is intended to provide
                 functionality that is difficult to implement
                 efficiently using a conventional hardware arrangement.
                 It allows a simple implementation of improved data
                 independence at high speeds. INDY simultaneously
                 satisfies the time windows of future hardware
                 technologies and user requirements. The importance of
                 strings as a mechanism for defining abstract data types
                 for data base languages is discussed in more detail in
                 another paper. In that paper, a language called STRING
                 is introduced which allows names of data objects to be
                 semantically defined as variable-length strings and
                 compared based on string pattern membership. This paper
                 is concerned with the implementation of string storage
                 and searching required by the STRING language.
                 Implementation of higher level structures and searching

                 architecture for text retrieval that provides a wide
                 range of query capabilities, without the use of indexes
                 of the material retrieved. A distributed approach is
                 employed, with direct search processors. Each search
                 processor is closely associated with one or more disk
                 drives that store the data to be searched and each
                 consists of a comparator for matching query terms,
                 logic elements to combine query terms, a disk
                 controller and a control minicomputer. The key element
                 of the architecture is the comparator, which can store
                 over 64,000 characters of query terms and compare all
                 of these terms simultaneously with data arriving from a
                 disk continuously at more than one million bytes per
                 second. Exact match, partial match, numeric comparison
                 and context limitation are among the capabilities
                 provided. The comparator is implemented as three
                 similar universal finite-state automata, with special
                 features to facilitate text retrieval and reduce
                 hardware costs. A breadboard version of the system with
                 one searcher is operational and has undergone detailed

                 Such a controller is also supposed to resolve the

                 that deadlock situations never arise. In this paper,

                 of distributed databases are investigated. In
                 particular, three controllers with hierarchical
                 architectures are considered. The controllers are
                 evaluated based on three criteria: (i) freedom of

                 conditions should also contribute to the amount of

                 concerning the Catalog of the Italian cultural and
                 artistic heritage have been made in the past by the
                 Institute for the Catalog and Documentation (ICCD) of
                 the Ministry of Cultural and Environmental Heritage. A
                 feasibility study for the realization of a data base of
                 the national cultural heritage has been conducted by
                 CNUCE, the scientific computing center of the Italian
                 National Research Council and ICCD. This study led to
                 the determination of the characteristics of data
                 contained on the record cards, to the location of some
                 samples areas, sufficiently representative of the
                 Italian situation, for the setting up of a model of
                 information system and to the implementation of a data
                 bank on CNUCE computers using the IBM STAIRS
                 information retrieval system. Following this study, a
                 project is presently conducted by the two institutions,
                 with the aim of setting up a distributed structure for
                 the preparation, acquisition, access to and
                 dissemination of the information concerning the Italian
                 cultural and artistic heritage. This paper describes
                 the functions of this proposed structure, with
                 reference to the results of the first experiences and
                 implementations.",

                 which claim a necessary and sufficient mechanism for
                 preserving the 'weak consistency' of databases. In
                 addition, we demonstrate that the notion of 'weak

  abstract =     "BUSINESS is a new application development language
                 intended to answer the needs of a rapidly growing user
                 community - the end-user. The underlying computational
                 model is the paper office. BUSINESS instructions
                 manipulate objects within this model in ways analogous
                 to human office workers. The syntax of BUSINESS closely
                 approximates a subset of English. Standard programming
                 functions are embodied in the language in ways that
                 seem natural to first time computer users. For example,
                 to open a file for exclusive read/write access one
                 'Pulls' a 'Folder' (containing 'Forms' and 'Documents')
                 from a 'Drawer' in a 'File Cabinet'. In the
                 computational model, the Folder is seen to actually
                 move from the Drawer to a 'Desk' belonging to an
                 'Aide'(the 'worker' inside the computer).To support the
                 construction of reliable software within this model,
                 BUSINESS contains a rich repertoire of structured
                 control constructs: execute (procedures), do
                 (routines), go through (a set of objects), test and
                 select one (from a set of 'if - then' instructions).
                 Base data types include: whole numbers, decimal
                 numbers, money, dates, times and characters. The set of
                 operators and tests within BUSINESS support a complete
                 range of data manipulations and logical decisions. Data
                 structures include Fillins (collections of Fields) and
                 Tables (having Entries at Row/Column intersections).
                 Permanent data is organized by Form (collections of
                 Fillins and Tables).",

                 associated with administering the system, so that
                 subsequent activities, such as documentation, training,
                 and staffing, can occur. Therefore, this paper
                 undertakes a careful definition of administrative tasks
                 for a Data Base Management System (DBMS) in a
                 distributed computer environment. The paper first
                 discusses a general framework for administering a
                 distributed DBMS, and then the paper presents a
                 specific listing of administrative functions. While the
                 above work is based on a specific system under
                 development at Bell Laboratories, the paper concludes
                 with several comments extending this work to other
                 types of distributed systems.",

                 inexpensive main memories, it is becoming possible to
                 keep large databases resident in main memory. This
                 paper considers the changes necessary to permit a
                 relational database system to take advantage of large
                 amounts of main memory. Authors evaluate AVL vs. B plus
                 -tree access methods for main memory databases,
                 hash-based query processing strategies vs. sort-merge,
                 and study recovery issues when most or all of the
                 database fits in main memory. As expected, B plus
                 -trees are the preferred storage mechanism unless more
                 than 80-90\% of the database fits in main memory. A
                 somewhat surprising result is that hash based query
                 processing strategies are advantageous for large memory
                 situations.",

                 which is implemented in the SABRE database system. The
                 specification language is simple. The enforcement
                 algorithm is general; in particular, it handles
                 referential dependency and temporal assertions.
                 Specialized strategies efficiently treat each class of
                 assertions. The system automatically manages integrity
                 checkpoints. Also, an efficient method is described for
                 processing assertions involving aggregates. An analysis
                 exhibits the value of the algorithms. It is shown that,
                 in general, this method is better than the query
                 modification method for domain assertions. Measures
                 have also been done for giving the cost added for
                 controlling integrity in comparison with the cost of
                 the request itself.",

                 compares them with a less restrictive structure, the
                 general multiway tree, and a more restrictive
                 structure, the compact B-tree. The authors compare
                 search cost, insertion costs, and space costs of these
                 three structures for both small and large orders and
                 indicate their relative utility for large and small
                 data sets. Although there are cases when general
                 multiway trees are more effective than B-trees, this is
                 not the case for most practical situations. Compact
                 B-trees are also shown to degrade rapidly in the
                 presence of insertions and are therefore only useful
                 for static data sets. 10 refs.",

  abstract =     "In order to handle spatial data efficiently, as
                 required in computer aided design and geo-data
                 applications, a database system needs an index
                 mechanism that will help it retrieve data items quickly
                 according to their spatial locations. However,
                 traditional indexing methods are not well suited to
                 data objects of non-zero size located in
                 multi-dimensional spaces. This paper describes a
                 dynamic index structure called an R-tree which meets
                 this need, and gives algorithms for searching and
                 updating it. The author presents the results of a
                 series of tests which indicate that the structure
                 performs well, and concludes that it is useful for
                 current database systems in spatial applications.",

  abstract =     "A new method for multikey access suitable for dynamic
                 files is proposed that transforms multiple key values
                 into a logical address. This method is based on a new
                 structure, called predicate tree, that represents the
                 function applied to several keys. A predicate tree
                 permits to specify in a unified way various hashing
                 schemes by allowing for different definitions of
                 predicates. A logical address qualifies a space
                 partition of a file according to its predicate tree.
                 This address is seen as a single key by a digital
                 hashing method which transforms it into a physical
                 address. This method is used to address records in a
                 file and to transform a retrieval qualification on a
                 file into a set of partitions to access. Finally, a
                 qualitative analysis of the behavior of the method is
                 given which exhibits its value.",

                 query answering device in systems using the Universal

                 projections of the representative instance to generate
                 the answer for a query. Associated with this approach
                 is the problem of how to generate the total projections
                 of the representative instance efficiently. A
                 generalization is proposed of extension joins, called
                 chase join expressions, as a means to compute the total
                 projections when functional dependencies are given as
                 constraints. In particular, an important subclass of
                 chase join expressions called simple chase join
                 expressions is identified and it is shown that the
                 total projections with respect to a set of functional
                 dependencies can be computed by unions of simple chase
                 join expressions when an independent scheme is assumed.
                 Also a simple and efficient algorithm is found that
                 minimizes the number of join operations in a union of

                 databases that are only loosely structured: heaps of
                 facts instead of highly structured data. This
                 architecture avoids the traditional dichotomy between

                 mechanism for defining both inference rules and
                 integrity constraints. As lack of organization will
                 usually have adverse effect on retrieval, the principal
                 retrieval method for loosely structured databases is
                 browsing: exploratory searching which does not assume
                 any knowledge of the organization (or even the very
                 existence of organization). Two styles of browsing,
                 called navigation and probing, are defined. Both are

  abstract =     "Atomic broadcast and failure detection are powerful
                 primitives for distributed database systems. In the
                 distributed database system, LAMBDA, they are provided
                 as network primitives. This paper shows how atomic
                 broadcast and failure detection simplify transaction
                 commitment, concurrency control, and crash recovery.
                 Specifically, a simple two-phase non-blocking commit
                 protocol is given; whereas three phases are required in
                 a point-to-point network. A simplified read-one\slash
                 write-all update algorithm is also given for replicated
                 data and an easily implemented log-based recovery
                 algorithm providing uninterrupted transaction
                 processing. The benefits of performing the atomic
                 broadcast and failure detection at the network level
                 are also discussed. Performing these functions at the
                 network level not only simplifies database protocols
                 but also better utilizes the broadcast network: fewer
                 messages are transmitted. Comparisons between LAMBDA

                 transactions, concurrency control and recovery. GEM
                 extends the relational model to support the notions of
                 entities with surrogates, the relationships of
                 aggregation and generalization, null values and
                 set-valued attributes, and provides simple extensions
                 of QUEL to handle these new constructs. In this
                 proposed implementation of GEM, the relational database

                 database applications. The knowledge base consists of
                 (1) facts regarding database objects that are organized
                 into a hierarchy of models, and (2) rules that specify
                 the behavior of objects within a model and among
                 models. The model hierarchy consists of database
                 application data, database schemas, data model
                 definitions, and system-related objects that control
                 the user's interaction with the system. The rules
                 governing the behavior of objects are specified as
                 explicit constraints on those objects. User goals are
                 transformed into conjectures that the inference engine
                 must prove are satisfiable by interpreting all
                 applicable constraints. The semantic architecture of

                 and semantics of the constraint language. PRISM is

                 existing database systems and provide a better tool for
                 database application programming, Servio Logic
                 Corporation is developing a computer system to support
                 a set-theoretic data model in an object-oriented
                 programming environment. The authors recount the
                 problems with existing models and database systems.
                 They then show how features of Smalltalk, such as
                 operational semantics, its type hierarchy, entity
                 identity and the merging of programming and data
                 language, solve many of those problems. Next they
                 consider what Smalltalk lacks as a database system:
                 secondary storage management, a declarative semantics,
                 concurrency, past states. To address these shortcomings
                 they needed a formal data model. They introduce the
                 GemStone data model, and show how it helps to define
                 path expressions, a declarative semantics and object
                 history in the OPAL language. They summarize similar
                 approaches, and give a brief overview of the GemStone
                 system implementation.",

  abstract =     "Since it has been first introduced, the concept of
                 transaction has become one of the fundamental
                 abstractions used in the design and analysis of
                 information systems that provide concurrent access to
                 share information. The basic idea of transactions is to
                 divide application programs into well defined units
                 that provide semantically correct transitions between
                 consistent states of the information system. In this
                 paper we outline an extended transaction model, which
                 we believe, is much more suitable for computing
                 environments consisting of autonomous systems. The
                 proposed model allows us to utilize knowledge of the
                 semantics of the application that is to be modeled by a
                 transaction. The model allows composition of flexible
                 transactions consisting of mutually dependent
                 substransactions. The execution of these
                 subtransactions may depend on the success of previous
                 subtransactions, and alternative sources of information
                 may be specified. This approach requires redefinition
                 of the notion of successful execution transactions,
                 their scheduling and commitment.",

                 a given level of accuracy. Next, we provide `sanity

                 way Arabic words are derived, classified, and
                 constructed. Furthermore, linguistic algorithms (for
                 word generation and morphological decomposition of
                 words) were designed, leading to a formalization of
                 rules of Arabic language writing and sentence

                 better facilitates the rigorous study of graphical
                 database end-user interfaces. In an earlier publication
                 authors introduced the Graph-Oriented Object Database
                 Model (GOOD). This model is built around a single
                 mathematical tool, namely graphs, to both model and

                 develop and investigate GOOD. They show that it has
                 many features generally present in existing semantic,
                 object-oriented and deductive database models.
                 Specifically, they demonstrate how the GOOD model is
                 suitable for graphically describing querying, browsing,
                 restructuring and updating databases, and hence is
                 ideally suited for the study and development of
                 graphically-oriented database end-user interfaces. To
                 demonstrate why GOOD is useful for advanced data

                 inheritance, and complex objects. OdeView provides
                 facilities for examining the database schema (i.e. the
                 object type or class hierarchy), examining class
                 definitions, browsing objects, following chains of

                 the internals of specific classes are not hardwired

  abstract =     "The expressive power of pure deductive database
                 languages, such as DATALOG and stratified DATALOG, is
                 limited in a sense that some useful queries such as
                 functions involving aggregation are not definable in
                 these languages. Our concern in this paper is to
                 provide a uniform logic framework for deductive
                 databases with greater expressive power. We propose a
                 logic for deductive databases which employs the notion
                 of `identifying each tuple in a relation'. Through the
                 use of these tuple-identifications, different linear
                 orderings are defined as a result. This intuitively
                 explains the reason why our logic has greater
                 expressive power. The proposed logic language is
                 non-deterministic in nature. However, non-determinism
                 is not the real reason for the enhanced expressive
                 power. A deterministic subset of the programs in this
                 language is computational complete in the sense that it
                 defines all the computable deterministic queries.
                 Although the problem of deciding whether a program is
                 in this subset is in general undecidable, we do provide
                 a rather general sufficient test for identifying such
                 programs. Also discussed in this paper is an extended
                 notion of queries which allows both the input and the
                 output of a query to contain interpreted constants of
                 an infinite domain. We show that extended queries
                 involving aggregation can also be defined in the
                 language.",

                 embedded in a database scheme over U that is

                 have developed for database systems research and
                 education. The uniform interface between operators
                 makes Volcano extensible by new operators. All
                 operators are designed and coded as if they were meant
                 for a single-process system only. When attempting to
                 parallelize Volcano, we had to choose between two
                 models of parallelization, called here the bracket and
                 operator models. We describe the reasons for not
                 choosing the bracket model, introduce the novel
                 operator model, and provide details of Volcano's
                 exchange operator that parallelizes all other
                 operators. It allows intra-operator parallelism on
                 partioned datasets and both vertical and horizontal
                 inter-operator parallelism. The exchange operator
                 encapsulates all parallelism issues and therefore makes
                 implementation of parallel database algorithms
                 significantly easier and more robust. Included in this
                 encapsulation is the translation between demand-driven
                 dataflow within processes and data-driven dataflow
                 between processes. Since the interface between Volcano
                 operators is similar to the one used in `real,'
                 commercial systems, the techniques described here can
                 be used to parallelize other query processing

                 extensively studied in the database and transaction
                 processing literature, but little has been said about
                 the handling of the requests for transaction execution.
                 In commercial TP systems, especially distributed ones,
                 managing the flow of requests is often as important as
                 executing the transactions themselves. This paper
                 studies fault-tolerant protocols for managing the flow
                 of transaction requests between clients that issue
                 requests and servers that process them. We discuss how
                 to implement these protocols using transactions and
                 recoverable queuing systems. Queuing systems are used
                 to move requests reliably between clients and servers.
                 The protocols use queuing systems to ensure that the
                 server processes each request exactly once and that a
                 client processes each reply at least once. We treat
                 request-reply protocols for single-transaction
                 requests, for multi-transaction requests, and for
                 requests that require interaction with the display

                 of datalog rule programs, mainly by processors that are
                 interconnected by a communication network. We introduce
                 a paradigm, called data-reduction, for the parallel
                 evaluation of a general datalog program. Several
                 parallelization strategies discussed previously in are
                 special cases of this paradigm. The paradigm
                 parallelizes the evaluation by partitioning among the
                 processors the instantiations of the rules. After
                 presenting the paradigm, we discuss the following
                 issues, that we see fundamental for parallelization
                 strategies derived from the paradigm: properties of the
                 strategies that enable a reduction in the communication
                 overhead, decomposability, load balancing, and
                 application to programs with negation. We prove that

                 the parallel, bottom-up evaluation of Datalog queries.
                 We introduce the notion of a discriminating predicate,
                 based on hash functions, that partitions the
                 computation between the processors in order to achieve
                 parallelism. A parallelization scheme with the property
                 of non-redundant computation (no duplication of
                 computation by processors) is then studied in detail.
                 The mapping of Datalog programs onto a network of
                 processors, such that the result is a non-redundant
                 computation, is also studied. The methods reported in
                 this paper clearly demonstrate the trade-offs between

                 control mechanisms are required to handle high level
                 abstract operations and to meet high throughput
                 demands. The currently available single level
                 concurrency control mechanisms for reads and writes are
                 inadequate for future complex information systems. In
                 this paper, we will present a new multilevel
                 concurrency protocol that uses a semantics-based notion
                 of conflict, which is weaker than commutativity, called
                 recoverability. Further, operations are scheduled
                 according to relative conflict, a conflict notion based
                 on the structure of operations. Performance evaluation
                 via extensive simulation studies show that with our
                 multilevel concurrency control protocol, the

                 complexity, there is genuine need to query this
                 repository of information. Moreover, since users of the

                 information that is data and information that is
                 knowledge, access to knowledge and data should be
                 provided with a single, coherent instrument. We provide
                 an informal review of various kinds of knowledge
                 queries, with possible syntax and semantics. We then
                 formalize a framework of knowledge-rich databases, and
                 a simple query language consisting of a pair of
                 retrieve and describe statements. The retrieve
                 statement is for querying the data (it corresponds to
                 the basic retrieval statement of various knowledge-rich
                 database systems). The describe statement is for
                 querying the knowledge. Essentially, it inquires about
                 the meaning of a concept under specified circumstances.
                 We provide algorithms for evaluating sound and finite

                 program consists of a number of modules (objects),
                 where each module is composed by a number of rules
                 possibly with negated head predicates. A sort of `isa'
                 hierarchy can be defined among the modules in order to
                 allow for rule inheritance. Therefore, every module
                 sees its own rules as local rules and the rules of the
                 other modules to which it is connected by the `isa'
                 hierarchy as global rules. In this way, as local rules
                 may hide global rules, it is possible to deal with
                 default properties and exceptions. This new approach
                 represents a novel attempt to combine the logic
                 paradigm with the object-oriented one in knowledge base
                 systems. Moreover, this approach provides a new ground
                 for explaining some recent proposals of semantics for
                 classical logic programs with negation in the rule
                 bodies and gives an interesting semantics to logic
                 programs with negated rule heads.",

                 characterizing the whole spectrum of interactions. The
                 ACTA framework is not yet another transaction model,
                 but is intended to unify the existing models. ACTA
                 allows for specifying the structure and the behavior of
                 transactions as well as for reasoning about the
                 concurrency and recovery properties of the
                 transactions. In ACTA, the semantics of interactions
                 are expressed in terms of transactions' effects on the
                 commit and abort of other transactions and on objects'
                 state and concurrency status (i.e., synchronization
                 state). Its ability to capture the semantics of
                 previously proposed transaction models is indicative of
                 its generality. The reasoning capabilities of this
                 framework have also been tested by using the framework

                 processing and that typically are of long duration. We
                 explore the use of triggers and transactions to specify
                 and organize such long-running activities. Triggers
                 offer data- or event-driven specification of control
                 flow, and thus provide a flexible and modular framework
                 with which the control structures of the activities can
                 be extended or modified. We describe a model based on
                 event-condition-action rules and coupling modes. The
                 execution of these rules is governed by an extended
                 nested transaction model. Through a detailed example,

                 the model for chaining related steps without

                 into a relational database system. Such a facility
                 allows definition of database operations that are
                 automatically executed whenever certain conditions are
                 met. In keeping with the set-oriented approach of
                 relational data manipulation languages, our production
                 rules are also set-oriented-they are triggered by sets
                 of changes to the database and may perform sets of
                 changes. The condition and action parts of our
                 production rules may refer to the current state of the
                 database as well as to the sets of changes triggering
                 the rules. We define a syntax for production rule
                 definition as an extension to SQL. A model of system
                 behavior is used to give an exact semantics for
                 production rule execution, taking into account

                 asserted fact against a collection of predicates to
                 find those rules that match the fact. Expert system
                 rule engines use a simple combination of hashing and
                 sequential search for this matching. We introduce an
                 algorithm for finding the matching predicates that is
                 more efficient than the standard algorithm when the
                 number of predicates is large. We focus on equality and
                 inequality predicates on totally ordered domains. This
                 algorithm is well-suited for database systems, where
                 predicate-testing speed is critical. A key component of
                 the algorithm is the interval binary search tree

                 Not only can views be specified by using rules but also
                 special semantics for resolving ambiguous view updates
                 are simply additional rules. Moreover, procedural data
                 types as proposed in POSTGRES are also efficiently
                 simulated by the same rules system. Lastly, caching of

                 performance enhancement and can be applied to
                 materialize views as well as to cache procedural data

                 do so, we first characterize the set of expression

                 graph, and investigate the existence of transformations

                 a combinatorial optimization problem, which makes
                 exhaustive search unacceptable as the query size grows.
                 Randomized algorithms, such as Simulated Annealing (SA)
                 and Iterative Improvement (II), are viable alternatives
                 to exhaustive search. We have adapted these algorithms
                 to the optimization of project-select-join queries. We
                 have tested them on large queries of various types with
                 different databases, concluding that in most cases SA
                 identifies a lower cost access plan than II. To explain
                 this result, we have studied the shape of the cost
                 function over the solution space associated with such
                 queries and we have conjectured that it resembles a
                 `cup' with relatively small variations at the bottom.
                 This has inspired a new Two Phase Optimization
                 algorithm, which is a combination of Simulated

  abstract =     "The R-tree, one of the most popular access methods for
                 rectangles, is based on the heuristic optimization of
                 the area of the enclosing rectangle in each inner node.
                 By running numerous experiments in a standardized
                 testbed under highly varying data, queries and
                 operations, we were able to design the R-tree which
                 incorporates a combined optimization of area, margin
                 and overlap of each enclosing rectangle in the
                 directory. Using our standardized testbed in an
                 exhaustive performance comparison, it turned out that
                 the R-tree clearly outperforms the existing R-tree
                 variants: Guttman's linear and quadratic R-tree and
                 Greene's variant of the R-tree. This superiority of the
                 R-tree holds for different types of queries and
                 operations, such as map overlay, for both rectangles
                 and multidimensional points in all experiments. From a
                 practical point of view the R-tree is very attractive
                 because of the following two reasons: 1. it efficiently
                 supports point and spatial data at the same time and 2.
                 its implementation cost is only slightly higher than
                 that of other R-trees.",

                 a parameter space. In the latter case, data objects are
                 transformed into points and query objects are
                 transformed into search regions. The requirement for
                 different data and query representations may prevent
                 the use of parameter-space searching in some
                 applications. Native-space and parameter-space
                 searching are compared in the context of a z
                 order-based spatial access method. Experimental results
                 show that when there is a single query object,
                 searching in parameter space can be faster than
                 searching in native space, if the data and query
                 objects are large enough, and if sufficient redundancy
                 is used for the query representation. The result is,
                 however, less accurate than the native space result.
                 When there are multiple query objects, native-space
                 searching is better initially, but as the number of
                 query objects increases, parameter space searching with
                 low redundancy is superior. Native-space searching is

                 as a means for optimizing query processing in
                 object-oriented database systems. The general idea is
                 to maintain redundant separate structures
                 (disassociated from the object representation) to store
                 object references that are frequently traversed in
                 database queries. The proposed access support relation
                 technique is no longer restricted to relate an object
                 (tuple) to an atomic value (attribute value) as in
                 conventional indexing. Rather, access support relations
                 relate objects with each other and can span over
                 reference chains which may contain collection-valued
                 components in order to support queries involving path
                 expressions. We present several alternative extensions
                 of access support relations for a given path
                 expression, the best of which has to be determined
                 according to the application-specific database usage
                 profile. An analytical cost model for access support
                 relations and their application is developed. This
                 analytical cost model is, in particular, used to
                 determine the best access support relation extension

                 behavior intraquery guidance. To enable this early,
                 active engagement in the user's process of query
                 creation, Kaleidoscope reduces the granularity of
                 user-system interaction via a context-sensitive menu.
                 The system generates valid query constituents as menu
                 choices step-by-step by interpreting a language
                 grammar, and the user creates a query following this
                 menu guidance. The approach of Kaleidoscope is based on
                 the normative system assumption. The system presents
                 its capability transparently to the user in a
                 context-dependent manner during the user's query

                 definition, schema and data browsing, query

                 being developed at Hewlett--Packard Laboratories. This
                 videotape provides an overview of the Iris data model
                 and a summary of our experiences in converting a
                 computer-integrated manufacturing application to Iris.
                 Iris is intended to meet the needs of new and emerging
                 database applications such as office and engineering
                 information systems, knowledged-based systems,
                 manufacturing applications, and hardware and software
                 design. The Iris data model is an object and function
                 model. It provides three basic constructs: objects,
                 types and functions. As with other object systems, Iris
                 objects have a unique identifier and can only be
                 accessed and manipulated through functions. Objects are
                 classified by type.",

                 prototype developed at IBM's Almaden Research Center.
                 The goal throughout its development has been to build a
                 complete relational database system kernel, engineered
                 throughout with the infrastructure for generic
                 extensions, rather than specific extensions for a
                 single application area not previously supportable by
                 relational technology. Currently, Starburst consists of
                 over 100,000 lines of C source code, and executes an
                 extended form of the SQL Data Definition Language and
                 the SQL SELECT and INSERT commands, including joins on
                 any number of tables. We demonstrate it on IBM's first
                 RISC-technology workstation, the RT\slash PC, under the

                 POSTQUEL (2) inheritance and its support in POSTQUEL
                 (3) use of the POSTGRES abstract data type system (4)
                 dynamic construction of new types (5) time travel over
                 the past history of the data base using the query
                 language (6) the use of the rule system for supporting
                 forward chaining triggers (7) dynamic inclusion of new
                 rules (8) use of the portals interface to couple to a
                 host programming language (9) addition of a new access
                 method to a running system. The videotape will be
                 constructed by recording a DECstation 3100 running
                 POSTGRES. We will run the demo on a large data base and
                 will refrain from speeding up the tape, so actual
                 response times can be observed. If there is time we
                 will also run Wisconsin benchmark. If we are lucky,
                 (i.e. POSTGRES development proceeds on schedule) we
                 will also show the rule system being used to support
