UNIDOOR: a Deductive Object-Oriented Database Management System

Abstract

In this paper, we present UNIDOOR, a deductive objectoriented database system (DOOD). We demonstrate the distinctive features of UNIDOOR data model and its query language. We then show how essential object-oriented and database management features, that were missing from other DOOD implementations, are successfully supported in UNIDOOR. These features include a scalable persistent store with crash recovery, database integrity and transaction control facilities in a multi-user environment.
