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…

This self-improvement manual developed for experienced online searchers presents and discusses several alternative search strategies and their appropriate use to achieve the desired outcome. The manual is divided into two parts: (1) an eight step model of the total search process emphasizing how the decision of the information professional affects…

Provides an overview of the development and use of numeric databases, and of the evolution of user charging methods for all online information retrieval systems. The need to provide database users with advance estimates of charges is discussed, and a methodology for charge estimation is presented. (87 references) (CLB)

Describes evolution of an in-house database search service developed by University of British Columbia's Educational Research Services and Computing Center. The tryout phase in developing a model for downloading citations to serve end users as a beginning nucleus for use in microcomputer accessed personal information systems is highlighted. (MBR)

Discusses data model role in an office filing facility, office data model requirements, and various modelling paradigms for office data modelling. Data model application to a typical collection of office data is presented, filing and retrieval operations are illustrated, and proposed research into other office data modelling aspects is outlined.…

This paper discusses the role of XML in library information systems at three major levels: as are presentation language that enables the transport of bibliographic data in a way that is technologically independent and universally understood across systems and domains; as a language that enables the specification of complex validation rules…

A pool of authority records for bibliographic entities (persons, corporate bodies, works/expressions, concepts, objects, events, and places) to use on the Internet is of interest, not only to libraries and their users, but also to publishers, copyright and rights management organizations, museums, and archives. This paper explores different models…

The entity-relationship (ER) approach to database design is defined, and a specific example of an ER model (personnel-payroll) is examined. The requirements for converting ER models into specific database management systems are discussed. (Author/MSE)

Discusses the growth in use and acceptance of Web-based genomic and proteomic databases (GPD) in scholarly communication. Confirms the role of GPD in the scientific literature cycle, suggests GPD are a storage and retrieval mechanism for molecular biology information, and recommends that existing models of scientific communication be updated to…
