Three operations relevant to preparing a data base and supporting scripts are discussed in considerable detail. Section One enumerates the activities which constitute the collection and documentation of a data base. The material presented is relatively nontechnical and requires no knowledge of computers. Section Two discusses the preparation of…

Chemical structure diagrams are considered as utterances in a written language. Two types of grammars are considered for this language: topological grammars and geometric grammars. The hypothesis is presented that compact computer storage may become accessible via grammars. (15 references) (Author/NH)

The Canadian Department of Education developed this manual to provide teachers and administrators with information about the potential use of computers. Part I describes at length the five components of the computer input, output, storage, control, and arithmetic/logic functions) and gives a discussion of computer languages, programing, batch…

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…

The computer language FOL is intended to facilitate the implementation of file organizations for information storage and retrieval systems. In many information storage and retrieval applications the designer, initially, does not know how best to organize a data base for efficient retrieval and ease of updating and modifying. It is felt that FOL…

The papers and discussions of the 1975 Pacific Region meeting of the Association for Computing Machinery are presented. Topics included (1) the current and emerging state of the art in data management software and hardware, (2) relational systems with particular attention to new developments in systems for relational data bases, (3) advances in…

The Information Sciences section of ITT Research Institute (IITRI) has developed a Computer Search Center and is currently conducting a research project to explore computer searching of a variety of machine-readable data bases. The Center provides Selective Dissemination of Information services to academic, industrial and research organizations…

A novel text analysis and characterization method involves the generation from text samples of sets of variable-length character strings. These sets are intermediate in number between the character set and the total number of words in a data base; their distribution is less disparate than those of either characters or words. The size of the sets…

Computer data on the technical level of devices, their speed rates, and computer languages of two Oakland County Michigan area centers' business data processing skill programs are discussed to provide information for other area centers on various hardware, software, and teachware. (BP)

This paper documents the program used in the application of the INFO system for data storage and retrieval in schools, from the viewpoints of both the unsophisticated user and the experienced programmer interested in using the INFO system or modifying it for use within an existing school's computer system. The opening user's guide presents simple…

The trend toward on-line utilization of computers in recent years has included the emergence of computer support systems to fill the information processing needs of individuals engaged in scientific research. In this study, a new approach to document description is applied to the design of a personal information storage and retrieval system,…

A multi-language, time-sharing system (MTS-12) has been developed for the PDP-12, a Digital Equipment Corporation laboratory computer. This low-cost, core-resident system features program storage on LINC tape (3/4" magnetic tape on a 4" reel), access to the high-level interpreted FOCAL language, and a special variable storage in the user…

Intended for teaching applications programing for libraries and information centers, this volume is a graded workbook or text supplement containing typical practice problems, suggested solutions, and brief analyses which emphasize programing efficiency. The computer language used is Programing Language/One (PL/1) because it adapts readily to…

Designed to provide a starting point for the teacher without computer experience, this booklet deals with both the "how" and the "when" of computers in education. Educational applications described include classroom uses with the student as a passive or an active user and programs for the handicapped; the purpose of computers…

Teacher background information and student materials are provided in this guide for teaching a one-semester data processing course, which may be used with or without microcomputer equipment. The material is organized into eight units covering history and evolution of data processing, information processing today, input/output media and devices,…
