One of the areas where demand has remained strong for MIS students is in the area of database management. Since the early days, this topic has been a mainstay in the MIS curriculum. Students of database management today typically learn about relational databases, SQL, normalization, and how to design and implement various kinds of database…

There are described methods used to minimize data files dimension. There are defined indicators for measuring size of files and databases. The storage optimization process is based on selecting from a multitude of data storage models the one that satisfies the propose problem objective, maximization or minimization of the optimum criterion that is…

Second installment of directory published in four parts in "Database" (June and August) and "Online" (July and September) provides descriptions of 17 laserdisk products together with information on the producer, compatibility, type of laserdisk, search and retrieval software, interface with magnetic media, conditions of usage, price, and status.…

Examines design functions of present file organizations in the context of available data storage devices and identifies current developmental trends. (Author/RAA)

The Compact Disc-Read Only Memory (CD-ROM) data format is explained and illustrated, noting current and potential applications. The "5-inch" compact laserdisc is described and photographs of an IBM PC/Hitachi CD-ROM system adopted by Library Corporation to support its MARC database--BiblioFile--are presented. Screen displays for…

Discusses software developed to organize and retrieve electronically stored data, examining structure of the databases in which information is stored and the physical structure of the storage medium. Hierarchical and relational databases, unordered files, B-trees, and storage/software for specific purposes (such as weather, stock market, and…

Discusses digital imaging technology and examines document database conversion considerations. Two types of document imaging systems are described: (1) a work in process system, and (2) a storage and retrieval system. Conversion methodology is outlined, and a document conversion scenario is presented as a practical guide to conversion. (LRW)

Fourth installment of a directory published in four parts in "Database" (June and August) and "Online" (July and September) provides descriptions of 12 laserdisk products together with information on the producer, compatibility, type of laserdisk, search and retrieval software, interface with magnetic media, conditions of usage, price, and status.…

Large central databases which support multicampus users require thorough planning and coordination, special communication with both users and input sources, and organized retrieval systems. In the developmental process of identifying variables that should be in the system and designating the source of that data, old habits of multiple official…

An interactive search and editing system, 3RIP, is being developed at the library of the Royal Institute of Technology in Stockholm for large files of textual and numeric data. A substantial part (on the order of 10-E9 characters) of the primary file of the search system will consist of bibliographic references from a wide range of sources. If the…

The Inverted File Information Retrieval System (INFIRS), is a document search system which offers a comprehensive range of search facilities. It has been developed at the United Kingdom Chemical Information Service (UKCIS) as a general purpose retrieval tool, suitable for handling a wide variety of data-bases (both free-text and controlled…

Introduces some algorithmic methods, for which no pre-editing is necessary, for automatically "lemmatising" raw text (changing raw text to an equivalent version in which all inflected words are artificially transformed to their dictionary look-up form). The results of a study of these methods, which used a German Text, are also given. (KM)

The purpose of this article is to describe a system for protecting the anonymity of subjects in longitudinal research and for maintaining the security of data files. The basic system comes from the American Council on Education Cooperative Institutional Research Program. Data is collected from questionnaires, and converted to magnetic tape.…

Social science data, existing in a format that can be manipulated by computing machinery, can be used for many purposes in addition to those for which they were initially collected. Scholars and government planners should hve ready and equal access to such material and these groups will be best served if they are informed regarding the…
