Analyzes structure of, and data in, the OCLC-MARC record in the form delivered via OCLC's Tape Subscription Service, and outlines important processing functions involved: "unreadable tapes," duplicate records and deduping, match processing, choice processing, locations processing, "automatic" and "input" stamps,…

Reviews hardware (microfilm, videodiscs, computers) which can process and retrieve large amounts of educational information. Identifies ways in which computer-based techniques can be used for course management, direct learning, and research. (Author/DC)

Traditional and table-driven methods of editing input data for a data-storage system are compared. An application of table-driven input editing is described for a high-volume, multiple-format, clinical data-base. (Author)

Extensions are required to the currently operational INGRES data base system for it to manage a data base distributed over multiple machines in a computer network running the UNIX operating system. Three possible user views include: (1) each relation in a unique machine, (2) a user interaction with the data base which can only span relations at a…

The objectives of this project were to assist the National Archives and Records Administration (NARA) in developing a policy for the representation, transfer, access, and preservation of electronic records of permanent value. A lack of attention to the management, retention, and selective preservation of these machine-readable records will result…

Discusses factors that should be considered by buyers and producers of databases on CD-ROM (compact disc-read only memory). The advantages and disadvantages of CD-ROM are also discussed and compared with those of magnetic and print media, and market projections are provided. (CLB)

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…

A relational data system (RDS) is one that has the capability not only to retrieve specific facts but also the ability to deduce facts that are implicit rather than explicit in the data base. The study investigated the application of RDS technology to intelligence data processing. RDS technology and the nature of intelligence data processing are…

An algorithm is proposed to solve the problem of sequential indexing which does not use any grammatical or semantic analysis, but follows the principle of emulating human judgement by evaluation of machine-recognizable attributes of structured word assemblies. (Author)

Provides a technological overview of CD-ROM (Compact Disc-Read Only Memory), an optically-based medium for data storage offering large storage capacity, computer-based delivery system, read-only medium, and economic mass production. CD-ROM database attributes appropriate for information delivery are also reviewed, including large database size,…

Provides an overview of how optical storage technologies--videodisk, Write-Once disks, and CD-ROM CD-I disks are built into and controlled via DEC, Apple, Atari, Amiga, and IBM PC compatible microcomputers. Several available products are noted and a list of producers is included. (EM)

Conversion of the Chemical Abstract Service scientific literature data base from Standard Distribution Format to a center-oriented file format, STF, is described. A tape file format is described in which variable length logical records, possibly longer than the blocksize, may be stored safely. (7 references) (Author/NH)

Describes how, when used effectively, data warehouses can be a significant component of strategic decision making on campus. Discusses what a data warehouse is and what its informational contents may include, environmental drivers and obstacles, and strategies to justify developing a data warehouse for an academic institution. (EV)

Seven experts in system planning offer their views on how optical disk systems will affect library participation in online networks, and discuss opportunities presented by these new products. (CLB)

This article defines three separate categories of microcomputers--personal, desk-top, multi-user devices--and relates storage capabilities (expandability, floppy disks) to library applications. Highlghts include de facto standards, operating systems, database management systems, applications software, circulation control systems, dumb and…
