Briefly describes some available database design tools and provides a detailed description and evaluation of the ER-Design Package, a sophisticated and comprehensive tool available on microcomputer. Some of the ER-Design functions evaluated include the main design module, diagram generation, conversion to relational schema, normalization of files,…

Investigates the value of applying principles derived from simulated annealing to clustering tuples in database design, and compares this technique with a graph-collapsing clustering method. It is concluded that, while the new method does give superior results, the expense involved in algorithm run time is prohibitive. (24 references) (CLB)

Describes the training and support offered to users upon the implementation of a corporate online text retrieval system, and offers insights from the experience. Areas discussed include training programs and objectives, user support services and support personnel, user documentation, database building, and performance evaluation and measurement.…

Argues that in-house database building offers possibilities for staff development, can provide important links between the library and the community, and can become important tools for local networking and cooperative collection development. Issues related to database planning, design, and testing are discussed, and several examples of existing…

Discusses the special needs of the depository library poster collection in academic libraries, especially with regard to improving public awareness and access. Suggestions for creating a bibliographic database are offered and a database at the University of Miami is briefly described. Appendices list poster items by issuing agency and subject…

Explores the underlying concepts involved in the design of art scholarly databases and describes three systems definition projects currently in progress. The discussion covers the revisions of MARC formats and authority controls used in bibliographic information networks that might support an art scholarly database. (eight references) (CLB)

Describes the Utlas database with specific reference to its design, file structure, and content. Features discussed include access to the database, products and services supported by the database, interfaces to local systems, the interactions between bibliographic and authority records, and Japanese language processing. (Author/CLB)

Introduces a hypertext data model for textual databases in which the text is divided into a syntactic structure, which describes the relationships of the text parts, and an access structure, which is generated from the syntactic structure by users' queries. Implementation considerations for the structuring component, retrieval component, and…

Discussion of computer systems that help teachers plan and manage the learning process focuses on the development of a computer consulting system, ASSISTANT, which was designed to help teachers choose the most suitable educational technology and evaluate its effectiveness. The organization of the database is explained. (seven references) (LRW)

Investigates the manipulation of large sets of two-dimensional data representing multiple overlapping features, and presents a new access method, the MOF-tree. Analyzes storage requirements and time with respect to window query operations involving multiple features. Examines both the pointer-based and pointerless MOF-tree representations.…

Investigates the role of data management in multimedia digital libraries, and its implications for the design of database management systems. Introduces the notions of content abstraction and content independence. Proposes a blueprint of a new class of database technology, which supports the basic functionality for the management of both content…

Even as weblogs, content management systems, and other forms of automated Web posting and journals are changing the way people create and place content on the Web, new Web pages mushroom overnight. However, many new Web designers produce Web pages that seem to ignore fundamental principles of "good design": full of colored backgrounds, animated…

During distributed virtual laboratory experiment sessions, a major problem is to be able to collect, store, manage and share heterogeneous data (intermediate results, analysis, annotations, etc) manipulated simultaneously by geographically distributed teammates composing a virtual team. The electronic notebook is a possible response to this…

Imagine if, at the start of the school year, a teacher could have detailed information about the academic history of every student in her or his classroom. This is possible if the teacher can log on to a Web site that provides access to an educational data warehouse. The teacher would see not only several years of state assessment results, but…
