Describes the advantages of optical data disk-based storage systems including cost, performance, and space required. Conversion from tape-based to optical disk-based data management via a flexible, hardware-based optical archiving system is discussed. (Author/LRW)

This report describes approaches to database translation (i.e., transferring data and data definitions from a source, either a database management system (DBMS) or a batch file, to a target DBMS), and recommends a method for representing the data structures of newly-proposed network and relational data models in a form suitable for database…

This paper provides a brief history of computers. It explains basic computer principles and compares computer capabilities. Subjects such as input/output, binary logic, storage, and cost are also discussed. (Author)

A detailed guide to selecting appropriate source data automation equipment is presented. Source data automation equipment is used to prepare data for electronic data processing or computerized recordkeeping. The guide contains specifications, performance data cost, and pictures of the major types of machines used in source data automation.…

This publication provides local governments in New York with guidelines and suggestions for three major records management undertakings: (1) writing an ordinance, resolution, or local law to establish a records management program; (2) defining the role of the Records Management Officer in developing, organizing, and directing a records management…

Consumers and producers of educational software must make decisions about what kind of software to buy and create. Both groups must base these decisions on criteria that consider what it is important to learn in our technological era, what is workable, and what is currently practical and cost-effective. Five criteria that are central to these…

This report delineates the theory and terminology of data compression. It surveys four data compression methods--null suppression, pattern substitution, statistical encoding, and telemetry compression--and relates them to a standard statistical coding problem, i.e., the noiseless coding problem. The well defined solution to that problem can serve…

The report describes an experimental study involving an on-line placement system in Boulder, Colorado which permitted applicants to request information from a terminal on any job stored in the computer. Data were collected on applicants referred by the Employment Service: whether or not hired, reason for not being hired if not hired, applicant…

Relative cost and effectiveness of techniques for preparing a computer compatible data base consisting of approximately one million words of natural language are outlined. Considered are dollar cost, ease of editing, and time consumption. Facility for insertion of identifying information within the text, and updating of a text by merging with…

The purpose of the research described in the report is twofold. First, it is to analyze the relative benefits and costs of on-line computerized placement systems. The techniques developed for such an analysis which might be useful in evaluating other manpower programs are presented. Second, it is to provide a prototype model which shows how…

Reviews technological developments centered around microcomputers that have led to the design of integrated workstations. Topics discussed include methods of information storage, information retrieval, telecommunications networks, word processing, data management, graphics, interactive video, sound, interfaces, artificial intelligence, hypermedia,…

The IADIS CELDA 2012 Conference intention was to address the main issues concerned with evolving learning processes and supporting pedagogies and applications in the digital age. There had been advances in both cognitive psychology and computing that have affected the educational arena. The convergence of these two disciplines is increasing at a…
