For about 10 years, several proposals to deal with ill-known information in database management systems have been made, and extensions of the relational data model have been proposed. An overview of functional dependencies is provided, and the connection between fuzzy functional dependencies and database design is discussed. (AEF)

This paper addresses the problem of data management techniques for efficiently retrieving requested subsets of large data sets from mass storage devices. Describes the development of algorithms and software that facilitate the partitioning of a large data set into multiple "clusters" that reflect their expected access. (Author/JKP)

This paper demonstrates the importance of effective planning when using database application programs in exceptional education programs, to more efficiently track students' performance, keep vital information, and create desired reports. The described approach, called the ends-to-means model, calls for developing the database by designing the…

Gives an overview of MEDLARS II as an example of a major bibliographic processing system that supports on-line access to a number of very large files, has efficient throughput, and is operated on a single large-scale computer. (Author/PF)

This manual on microcomputer-based database management programs provides a description of the key characteristics of database software as well as guidelines for designing a database, uses of database programs, and selecting the right software. Three sets of concepts related to database management are listed and explained: creating a database,…

Institutional researchers play a key role in an environment where data warehouses are used to store and retrieve vast amounts of data. Along with the benefits of increased access for more users, improved reporting capabilities, and less reliance on centralized information, come questions of appropriate data usage, data access and security,…

The World Energy Data System (WENDS) allows qualified users on-line access to non-classified management level data on worldwide energy technology and research and development activities. Information is arranged on textual pages and available by means of a simple accessing procedure. Described in this report are the WENDS concept and approach, the…

This report discusses the management of scientific and technical bibliographic data bases by the Federal Government, the existence of overlapping and duplicative bibliographic information services, the application of cost recovery principles to bibliographic information services, and the need to manage information as a resource. Questionnaires…

Gives advice on the evaluation, purchase, and setup of a computerized student database for consolidation of scheduling, attendance, grades, and other recordkeeping tasks. Recommends questions to be asked and outlines a workable system configuration. (JM)

A subset of data base management techniques for the hardware/software functions necessary to support a management information system are discussed. Seven basic dimensions of data base design are: (1) data base life span, (2) logical record growth, (3) record content growth, (4) data set organization, (5) linkages, (6) design criteria and (7)…

The trend to distributed processing is being fueled by numerous forces, including advances in technology, corporate downsizing, increasing user sophistication, and acquisitions and mergers. Increasingly, the trend in corporate information systems (IS) departments is toward sharing resources over a network of multiple types of processors, operating…

The second of two volumes of a conference preceedings, this volume contains the preprints of five submitted papers, which are published as submitted by the authors: M. Broadbent and L. B. McIntyre, "Information Management: Promise and Reality"; E. Spoor, "Management Information from Library Systems"; R. Walsh, "Integrated…

This state-of-the-art survey of non-bibliographic databases and their use within the fields of economics and business studies recommends that schools of librarianship and information science incorporate online teaching packages encompassing such databases in their programs. The review, conducted through on-site visits and a questionnaire, focuses…

This discussion of current microcomputer technologies available to libraries focuses on software applications in four major classifications: communications (online database searching); word processing; administration; and database management systems. Specific examples of library applications are given and six references are cited. (EJS)

Designed to assist educational researchers in utilizing microcomputers, this paper presents information on four types of computer software: writing tools for educators, statistical software designed to perform analyses of small and moderately large data sets, project management tools, and general education/research oriented information services…
