Abstract

When processing a query in a conventional database systems, a set of facts or tuples are usually returned as an answer. This also applies to object-oriented database where a set of objects is returned. Deductive database systems, however, provide the opportunity to obtain the answer of a query as a set of formulas, thereby reduce the costs to process the query, and represent its "intensional answers" in a more compact way independently of the database state. In this paper, by introducing rules into the object-oriented database systems and integrating the intensional query processing of deductive database systems into the object-oriented database systems, we make it possible not only to answer incomplete queries which are not able to be answered in conventional object-oriented database systems, but also to express the answer-set abstractly as the names of classes, which provides us better understanding of the answer.
