Abstract :
A deductive rule-based language for object-oriented databases is presented. A deductive rule in this language derives new patterns of associations among objects of some selected classes if these objects fall in certain `base´ on other derived patterns. The patterns of object associations derived by a rule are held in a subdatabase whose intention consists of some selected classes and their associations. In other words, the structure of a derived subdatabase is represented using the structural constructs provided by the object-oriented data model and hence can be uniformly operated on by other rules to further derive new subdatabases. Therefore, the world of subdatabases is closed under this rule-based language
