Researchers and practitioners are paying increasing attention to blockchain's potential for resolving trust, privacy, and transparency-related issues in smart education. Research on educational blockchain is also becoming an active field of research. Based on 206 studies published from 2017 to 2020, we identify contributors, collaborators,…

Explores the information storage potential of videodiscs through comparisons of several videodisc sytems now on the market or under development. A table shows compared costs and storage capacities for microfiche, floppy discs, and three types of videodisc systems. (SW)

Describes recent attempts to make explicit connections between the indexing process and the use of the index or information retrieval system, particularly the utility-theoretic and automatic indexing models of William Cooper and Stephen Harter. Theory and performance, information storage and retrieval, search stage feedback, and indexing are also…

This 14-item annotated literature review summarizes and analyzes scientific developments in and applications of optical and videodisc technology. Implications for information storage and retrieval, prospects for the optical disc in the office, preservation and the new technology, electronic document delivery, and the impact of technology on…

Developments in the representation of music, in notated and acoustic forms, in computerized databases suggest a need for nontext searching. Examines aspects of music notation and sound and reviews literature concerned with basic considerations of musical document representation; systems for encoding music for storage, regeneration, and analysis;…

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

Examination of management information systems of three manufacturing firms highlights principal characteristics, document types and functions, main information flows, storage and retrieval systems, and common problems (corporate memory failure, records management, management information systems, general management). A literature review and…

Details distinction between digital and analog data, advantages of analog storage, and optical disc use to store analog data. Configuration and potential of three levels of laser disc systems are explained. Selection of display devices for use with laser disc systems and accessing audio data are addressed. (Continued in next issue.) (EJS)

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…

The market availability of optical storage technology will radically change the nature of information distribution, especially by reducing the high cost of mass data storage. The three general classes of optical storage are: (1) mass-produced read-only storage, (2) write-once storage, and (3) erasable optical storage. (CDD)

This article examines some of the many overlapping, and even conflicting, terms used in the field of human memory and aging, analyzes the research approaches used to study those terms, and discusses the implications for adult education that result from the research findings. (CT)

Describes new technology known as videodisc, including optical videodisc, capacitance electronic disc, and video high density disc. Entertainment, educational, training, and information storage and retrieval potentials of videodiscs are discussed. A list of agencies active in optical disc applications, useful Canadian videodisc contacts, and a…

Introduction to use of compact disk technology for storing digital data highlights history, background, and developments; technical features; standardization issues; current CD ROM applications; and the market for CD products. A production diagram, a sampling of CD manufacturers and disk replicators, and performance comparison of three storage…

Five categories of microcomputer software for information storage and retrieval (ISR) are distinguished and characterized: classical retrieval systems; end-user software; indexing programs; full-text retrieval programs; and personal information managers. In addition, the special retrieval techniques of hypertext and best-matched searching are…

Designed to provide guidance in selecting appropriate software for library automation, information storage and retrieval, or management of bibliographic databases, this inventory describes 188 computer software packages. The information was obtained through a questionnaire survey of 600 software suppliers and developers who were asked to describe…
