Online bibliographic and network-based information systems are starting to blur the boundaries that separated print documents. Two concepts emerge as a consequence: the union record, an entity that combines multiple catalog records for a single bibliographic item; and an information dossier, a hypertext-like information object built by linking…

Describes the changes scientific abstracting and indexing services are making to develop new production systems for a marketplace which is influenced by the information superhighway and the demand for information in an electronic format. Descriptions are included of computer system and data input changes implemented by several database producers…

Discusses the development of multiobject databases called large data constructs (LDC), which may contain images and recorded or synthesized voice as well as text. Virtual reality and cyberspace are discussed, selectivity and database content are examined, database management systems are described, and retrieval options are reviewed. (three…

This document contains abstracts of papers on database design and management which were presented at the 1986 mid-year meeting of the American Society for Information Science (ASIS). Topics considered include: knowledge representation in a bilingual art history database; proprietary database design; relational database design; in-house databases;…

Describes ERA (Electronic Redistribution and Archiving), a new service on Dialog, that provides both users and database producers with a legal means of registering multiple, systematic use of copyrighted material. Costs and pricing are explained; inclusion of copyright notices on database records is discussed; and compliance is considered. (LRW)

Discusses issues involved in automating the relational database design process for microcomputer users and presents a prototype of a microcomputer-based system (RA, Relation Assistant) that is based on expert systems technology and helps avoid database maintenance problems. Relational database design is explained and the importance of easy input…

Different simple and inexpensive ways of building a database using common computer software and data from local newspaper are presented. Creating one's own database provides an opportunity to discuss ethical issues in data collection as well as data integrity.

Discussion of bibliographic databases and the structure of records focuses on the structure of education information based on publications of the New Zealand Council for Educational Research. Faceted design is discussed, and mandatory and optional fields in education database design are considered. (Contains 16 references.) (LRW)

Notes that advances in new technologies and uses of databases have expanded the definition of publics and increased the ability to target messages to narrower and narrower ranges of publics. Explores the implications of these developments for the public relations profession. (RS)

Proposes an object-oriented conceptual data model tailored for organizing and representing basic map elements and their relationships, as well as operations of interest for the management of geographic data. Discussion includes both conceptual abstraction primitives (classification, generalization, and aggregation) and a spatial abstraction…

Raises questions about the validity and reliability of doing research online via the proliferation of academic databases. Finds different versions of the Lexis-Nexis database have differing search capabilities. Argues that dependence on database research findings means dependence on decisions made by a few people who design search engines and…

Presents the design and implementation of a deductive object-oriented database which is built upon a formally defined data model that uses two languages: an imperative programming language called ROCK (Rule Object Computation Kernel), and a logic language called ROLL (Rule Object Logic Language). (LRW)

Describes a hierarchical text database model and defines an algebra based on concordance lists. The algebra is presented as a theoretical model to define both a conceptual schema for the database and search protocols for database implementation. Several retrieval examples are included. (19 references) (MES)

Describes a conceptual design of a bibliographic retrieval system that enables more thorough control of bibliographic entities. The conceptual schema describes a database comprising two separate files of bibliographic description, one of intellectual works and the other of physical items. This model provides information about a work's association…

A hierarchical extension to the American National Standard for Bibliographic Information Interchange on Magnetic Tape is defined and described. The accommodation of the extension within the existing standard is discussed, modifications to the existing standard are proposed, and applications of the hierarchical format are presented. (21 references)…
