Hyperdatabase: A schema for browsing multiple databases

Abstract

In order to insure effective information retrieval, a user may need to search multiple databases on multiple systems. Although front end systems have been developed to assist the user in accessing different systems, they access one retrieval system at a time and the search has to be repeated for each required database on each retrieval system. More importantly, the user interacts with the results as independent sessions. This paper models multiple bibliographic databases distributed over one or more retrieval systems as a hyperdatabase, i.e., a single virtual database. The hyperdatabase is viewed as a hypergraph in which each node represents a bibliographic item and the links among nodes represent relations among the items. In the response to a query, bibliographic items are extracted from the hyperdatabase and linked together to form a transient hypergraph. This hypergraph is transient in the sense that it is ``created`` in response to a query and only ``exists`` for the duration of the query session. A hypertext interface permits the user to browse the transient hypergraph in a nonlinear manner. The technology to implement a system based on this model is available now, consisting of powerful workstation, distributed processing, high-speed communications, and CD-ROMs. As the  More>>
