The DURESS project: Extending databases into an open systems architecture

Abstract

The DURESS (Distributed University Research and Education and Support System) project is a joint effort of the Database and Information Systems Group at the Johann Wolfgang Goethe-University, Frankfurt, and the IBM European Networking Center, Heidelberg, West-Germany. In the DURESS project, the applicability of an integrated database and programming language is extended into an open distributed environment. The extended a chitecture allows for distributing database ‘modules‘ over separate nodes in a computer network and for accessing components of such modules in a distribution transparent way. In a corresponding prototype, it is demonstrated how the necessary database management and communication system extensions can be realized, exemplarily, based on a centralized DBMS and supported by standard ISO/OSI communication facilities.
