Outlines procedures for the application of data processing technology to media center functions, and explains four steps in designing a database: preliminary design, selection of software, detailed design, and design evaluation. (LRW)

Discusses properties of multiple attribute tree (MAT) and inverted file structures; establishes suitability of MAT data structure for bibliographic files using worst-case performance measures; provides arguments to establish MAT average case superiority; and proposes an efficient adaptation of MAT data structure to exploit special features of MAT…

Describes EDP (electronic data processing) insurance, which provides coverage for such things as the loss of computer programs and accumulated transaction data, and the consequences of an interruption in processing. Discusses what is and is not covered by EDP insurance, how to plan for EDP insurance, the amount of coverage to get, and how to avoid…

Among other improvements in chemical nomenclature used in the Chemical Registry System, Chemical Abstracts Service intends to standardize the fundamental principles for naming cyclic structures so that procedures for the derivation of ring names can become more amenable to computer generation and translation. (Author/NH)

The ability of operating departments of an institution to mechanically gather, summarize, and report "local" data is discussed. Problems are outlined that arise when departments have the ability to produce data and do so with rigorous quality control by the institution's central information management organization. (MLW)

Provides a generalized overview of the problems that software buyers are likely to encounter and could overcome. Experiences of Online, Inc., in purchasing programs, using software documentation or manuals, and problems with software, provide examples. (EJS)

Reports the findings of a study which examined the question of submitting error reports to OCLC for the purpose of database quality control, and describes ENHANCE, a program that would provide online error correction capability for member libraries. Eight references are cited. (FM)

Discusses database structure, concepts, and management systems in library settings and describes the Comprehensive Automated Learning Resource System (CALS). This system was developed by NILRC to meet the needs of libraries which incorporate print and audiovisual materials in their collections. (RAA)

Presents the results of a detailed study of errors in a musical database. Provides an equation for estimating the effect of an overall error-rate on arbitrary analytic measures derived from the database. Examines four methods of error detection: manual proof-reading, double-entry method, programed syntactic checking, and programed heuristics. (GEA)

This document explains recent developments in computer science and information systems of interest to the educational manager. A brief history of computers is included, together with an examination of modern computers' capabilities. Various features of card, tape, and disk information storage systems are presented. The importance of time-sharing…

Based on existing literature and user experience, the systematic approach to data base evaluation presented here provides a method by which data processing administrators can optimize the probability of selecting the data base management system best suited for their institution. (Author/WM)

A look at Moraine Valley Community College's data bank for systematically gathering, reporting and updating community socioeconomic data for occupational program planning and counseling. (Author)

Discusses the new languages and software packages that make up data base management systems, outlines the characteristics of the systems, and examines the benefits claimed for them. (IRT)

The file organization for the computerized Flora North America (FNA) data bank is described. A four level character hierarchy allows subdivision of any flora description into as many as four levels in order to specify plant character precisely. Terms at any one level will not necessarily be parallel in status. Both PLANTS and LEAVES serve as…

This is a progress report on a project attempting to design a system of compacting text for storage appropriate to disc oriented demand searching. After noting a number of previously designed methods of compression, it offers a tentative solution which couples a dictionary of most frequent character-strings with a set of variable-length codes. The…
