    Rapid advances in semiconductor fabrication technology have resulted in an explosion of the number of components realizable on a Very Large Scale Integrated (VLSI) circuit. The design process which exploits this technology is extremely complex and must be supported by a project environment. To this end we examine the design process. The goal of VLSI design is to ‘compile’ a high leve... View full abstract»

  • A natural language interface for performing database updates

    Publication Year: 1984, Page(s):69 - 76
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (864 KB)

    Although natural language database interfaces have been developed for query processing, the problem of natural language updates has not generally been considered. To interpret update requests, several issues must be addressed that do not typically pose difficulties when dealing exclusively with queries. This paper examines the problems encountered, and describes an implemented system that performs... View full abstract»

    Since cooperation is an essential aspect of human conversation, it is a necessary feature in a natural language interface. Previous work has shown that it is possible to incorporate principles of cooperative behaviour into a system allowing natural language access to a database. It is shown here that some of these principles can also be applied fruitfully in a formal language environment. Specific... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (840 KB)

    MALPHA is a language for manipulations of data that constitute collections of relational databases. It generalizes to this environment the well known database manipulation language ALPHA of E. Γ. Codd. The principles that MALPHA proposes may also lead to MQUEL, MSQL etc. Since users typically face more than one database, the multidatabase manipulation languages should reveal more useful tha...

  • Diophantine inferences from statistical aggregates on few-valued attributes

    Publication Year: 1984, Page(s):107 - 110
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (560 KB)

    Research on protection of statistical databases from revelation of private or sensitive information [Denning, 1982, ch. 6] has rarely examined situations where domain-dependent structure exists for a data attribute such that only a very few independent variables can characterize it. Such circumstances can lead to Diophantine (that is, integer-solution) equations whose solution can lead to surprisi... View full abstract»

    The growing mountain of information in the form of numeric data poses a significant problem for those activities that support the data user. Existing database management systems are designed to connect data elements into records and produce reports — frequently in the form of tables. Tables of data, however, acquire a subsequent life of their own. They are analyzed, reworked, and combined w... View full abstract»

  • A method for optimization of a conceptual model

    Publication Year: 1984, Page(s):126 - 132
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (801 KB)

    Optimization of a conceptual model is a non-trivial task. A set of rules for determining the "best" one out of a number of candidate solutions is introduced. A key point is the definition of a set of quantifiable characteristics of a conceptual model; a measurement of the characteristics together with a fixed measurement of the decision-maker's preferences are used to quantify the qu...

  • Representing roles in universal scheme interfaces

    Publication Year: 1984, Page(s):133 - 142
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1124 KB)

    In universal scheme interfaces to relational databases, an attribute name must represent a unique role in the database, so that the connection among a set of attributes is unambiguous. A drawback to this requirement is that several attributes can represent the same underlying class of of entities, but the relationship among those attributes is not captured in the database scheme. As our method for... View full abstract»

    Database models provide concepts and tools to establish data-based models of complex real-world applications. The currently prevalent set-oriented and record-based data models provide powerful and quite adequate structural tools for modelling formatted data objects in data intensive applications. Limitations of traditional database models become obvious, however, when modelling such advanced ... View full abstract»

  • Dynamic data structures on optical disks

    Publication Year: 1984, Page(s):175 - 180
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (666 KB)

    Current data structures for online secondary storage depend on the ability to alter data once it is written. On an optical disk such modification is not possible, so new approaches are needed. In this paper, data structures which allow additions, logical deletions, and rapid access to data stored on optical disks are proposed and analyzed. View full abstract»
