Performance is a critical factor hindering the use of object-oriented databases (OODB). This article proposes a new and uniform indexing scheme for enhancing OODBs with advantages for small range, clustered sets queries. Reviews several other indexing schemes; presents the U-index scheme; discusses its performance; and presents experimental…

Discusses the use of XML for data integration to move data across different platforms, including across the Internet, from a variety of sources. Topics include flexibility; standards; organizing databases; unstructured data and the use of meta tags to encode it with XML information; cost effectiveness; and eliminating client software licenses.…

Presents a survey of the French indefinite "tu/vous" in in earlier periods and in a range of varieties. Draws on a corpus of French spoken in Picardy in Northern France to investigate the extent to which this use of second person pronouns helps to avoid ambiguity and co-occurs with another grammatical variable.

Presents a historical overview of the concept of copyrights as background for a detailed analysis of the licensing elements used for the protection of databases. The ramifications for the introduction of gateway systems without appropriate controls are discussed. (One reference) (CLB)

Defines data base for Army Selection and Classification Project (Project A) as containing two major samples: concurrent validation sample and longitudinal validation sample. Describes data base resulting from concurrent sample, sampling procedure, distribution of sample sizes over jobs, total array of variables, and data collection procedures.…

Discusses the problem of processing fuzzy queries in databases and information retrieval systems and presents a prototype of a fuzzy query processing system for databases that is based on data clustering and uses Pascal programing language. Clustering schemes are explained, and the system architecture that uses natural language is described. (14…

This study compared online versions of LISA (Library and Information Science Abstracts), Library Literature, and ERIC to investigate time lag and duplication of coverage. Six searches of each database were executed over a period of 15 months. Results indicated that Library Literature had the least time lag and LISA the most; duplication was low.…

Introduces DACUM (a process designed to help colleges develop, update, or evaluate a curriculum or training program) and its resulting national database. Describes how DACUM can be used to justify the study of communication in most academic curricula, to guide speech communication curriculum planning and defining of the basic course, and to…

Proposes a new lock primitive called ordered sharing that allows increased concurrency in database systems. Reliability and performance issues of the proposed protocol are addressed, a simulation study that demonstrates that ordered sharing results in improved performance in database systems is described; and use in several representative database…

This article has three objectives: (1) introduce the basics of the World Wide Web (including Internet connectivity, hypertext, and uniform resource locators); (2) highlight environmental health databases on the Web; and (3) discuss possible applications of the Web for the environmental health profession.

Edwards (1992c) concerns data and data use rather than manuals. It presents principles to facilitate reliable archive research in an imperfect world. MacWhinney and Snow (1992) endorse the principles but disagree on important details, discussed in this response. (21 references) (KM)

Following an introduction to authority control and MARC (machine readable cataloging), 10 steps are presented for making the transition from a manual to an automated authority file, keeping up with ongoing work, staying current in the discipline, and retrospective work. (23 references) (MES)
