Query processing techniques of the interactive interface system in CIMBASE system are dis- cussed in this paper,including the object association algebra,the object association calculus,and the transla- tion algorithms from the object association algebra to the object association calculus and from the object asso- ciation calculus to data languages of relational database systems.

After presenting the model of object assembling, the mechanism of its language description and implementation are described, which is based on object hook interfaces, rather than the ordinary object interfaces, and through which the domain-oriented dynamic manipulation of object association and automatic maintenance of association semantics are achieved.
