Enumerates principal management objectives of database management systems (data independence, quality, security, multiuser access, central control) and criteria for comparison (response time, size, flexibility, other features). Conventional database management systems, relational databases, and database machines used for backend processing are…

Reviews the state of research in text mining, focusing on newer developments. The intent is to describe the disparate investigations currently included under the term text mining and provide a cohesive structure for these efforts. A summary of research identifies key organizations responsible for pushing the development of text mining. A section…

This paper presents a cognitive account of both the advantages and disadvantages of direct manipulation interfaces, i.e., the use of icons to manipulate and interact directly with data rather than writing programs or calling on a set of statistical subroutines. Two underlying phenomena that give rise to the sensation of directness are identified.…

This discussion of the design of computerized psychological assessment or testing instruments stresses the importance of the well-designed computer-user interface. The principles underlying the three main functional elements of computer-user dialogue--data entry, data display, and sequential control--are discussed, and basic guidelines derived…

Describes hypertext as software that improves the learner's control over a knowledge base, and discusses the role hypertext could play in compact disc technologies. Digital multimedia learning materials are discussed; relationships among data, information, knowledge, and expertise are explored; and examples of applications of compact disc media…

Examines the need for medium to large academic libraries to have a policy for staff use of microcomputers. Key issues that should be covered in such a policy are outlined, including rules for acquisition and use, compatibility of hardware and software, and data administration. A model policy is provided. (CDD)

Argues that a mix of quantitative and qualitative measures is most efficacious in library collection analysis. Cases drawn from the literature in which a combination of these measures was profitably applied are considered, and the types of software packages for purposes of data manipulation are discussed. (Contains 15 references.) (KRN)

Defines cognitive computer tools as software programs that use the control capabilities of computers to amplify, extend, or enhance human cognition; suggests seven ways in which computers can aid learning; and describes the "Learning Tool," a software package for the Apple Macintosh microcomputer that is designed to aid learning of…

Description of a Canadian research and development project that involved the development of a library information system which would satisfy the needs of a variety of libraries focuses on the technological aspects of the system. Data manipulation is discussed, software is described, standards are considered, and customer requirements are examined.…

This composite report provides summaries of presentations by 10 experts at the 23rd Annual Clinic on Library Applications of Data Processing in April 1986 at the University of Illinois at Urbana-Champaign. All were concerned with the design of online systems to make them easier for library patrons to use. (Author/CDD)

The widespread use of the micro/personal computer and related technological advancements are having important impacts on information management in the modern electronic office. Some of the most common software applications include word processing, spread sheet analysis, data management, graphics, and communications. Ancillary hardware/software…
