Towards Integration Of Deductive Databases And Object-Oriented Databases: A Limited Survey

There have been many proposals for extensions of relational databases. It can be considered that two major streams of them are DDBs and OODBs. Research on fusion or integration of their advantages has been being done at the forefront of research on database and logic programming. For the target, the first international conference on deductive and object-oriented databases (DOOD89) was held in Kyoto. In this paper, we propose a framework for the extensions along these lines, and introduce some research results such as /-term, O-logic, F-logic, DOT and hierarchical deductive databases, in the framework, and discuss future directions. 1 Introduction As extensions of relational databases or new databases (data models), there have been many proposals such as deductive databases (DDBs), nested relations, complex objects, semantic data models, and object-oriented databases (OODBs). As their background, there are various reasons such as maturity of relational database technologies, enlargeme..
