This description of ways in which database management systems can be helpful in instructional media centers explains the basic terminology involved and how to plan, create, modify, maintain, and use databases. Examples provided include an equipment distributions form and the structure for a film/video rental database. (LRW)

Discusses deductive databases and database management systems (DBMS) and introduces a framework for advanced query formulation for end users. Recursive processing is described, a sample extensional database is presented, query types are explained, and criteria for advanced query formulation from the end user's viewpoint are examined. (31…

Reports on a project showing that relational data models, including unnormalized models that allow the nesting of relations, cannot fully capture the structural properties of lexical information. A feature-based model that allows for a full representation of some nesting and defines a factoring mechanism is described and demonstrated. (38…

Describes a computer program that manages a collection of pictures such as photographic slides, overheads, or computer images in one or more databases. Discusses organizing the database, searching, and keeping track of the time needed to present the images. (Author/LRW)

Investigates the impact of the Internet on the UK (United Kingdom) second-hand and antiquarian book trade. Results from questionnaires and interviews showed that, overall, electronic commerce presents an opportunity rather than a threat to this traditional retailing sector, partly due to pre-existing database management and distribution skills.…

Grade earned and class attendance records were examined to determine if posting PowerPoint notes on a web-based course management system was related to enhanced performance or increased absences. There were no differences in either grades or absences between classes that had notes posted and those that did not. However, results indicated…

This article develops an environment for mobile e-learning that includes an interactive course, virtual online labs, an interactive online test, and lab-exercise training platform on the fourth generation mobile communication system. The Next Generation Learning Environment (NeGL) promotes the term "knowledge economy." Inter-networking…

This paper introduces blended learning as a pedagogical approach, which was explored through the European project InnoEd and the way InnoEd undertook by using the on-line InnoEd VRLE. European educators in the InnoEd project have utilised a range of learning activities to help to improve Innovation Education. A mixture of lectures, visual…

This paper describes how a technology-based case using Microsoft Access can aid in the assessment process. A case was used in lieu of giving a final examination in an Accounting Information Systems course. Students worked in small groups to design a database-driven payroll system for a hypothetical company. Each group submitted its results along…

State policymakers are increasingly focused on closing the achievement gap and preparing all students to succeed in school and in life. However, college and career readiness begins long before students enter high school or even a classroom. Differences in children's abilities appear as early as the first year of life, and research has shown that…

This review of the book, "Conceptual Structures: Information Processing in Mind and Machine," by John F. Sowa, argues that anyone who plans to get involved with issues of knowledge representation should have at least a passing acquaintance with Sowa's conceptual graphs for a database interface. (Used to model the underlying semantics of…

Proposes that the development of document-retrieval systems can benefit from the incorporation of conceptual modeling techniques, specifically classification, aggregation, and generalization. An array model is presented which has been designed especially for document retrieval. (Author/EM)

Assesses bibliographic databases as part of visionary text systems such as hypertext and scholars' workstations. Downloading is discussed in terms of the capability to search records and to maintain unique bibliographic descriptions, and relational database management systems, file managers, and text databases are reviewed as possible hosts for…

Discusses the use of multimedia databases to track information from Web sites and to develop Web sites over the Internet. Four different types of databases are described: relational models; object oriented; relational-object hybrids; and specialty databases. Vendor contacts are listed. (LRW)

Describes the evaluation of four relational database management systems (RDBMSs) (Informix Turbo, Oracle 6.0 TPS, Unify 2000 and Relational Technology's Ingres 5.0) to determine which is best suited for library automation. The evaluation criteria used to develop a benchmark specifically designed to test RDBMSs for libraries are discussed. (CLB)
