Abstract

One of the common features of existing object-oriented database systems is the support of an inheritance hierarchy, which allows the user to create new classes incrementally from existing, less specialized classes. However, the traditional inheritance notion seems to suffer from several limitations: (1) susceptiveness to incomprehensible conceptual semantics, (2) susceptiveness to class space pollution, and (3) rigorousness of the overriding mechanism that restricts objects to present only a single view of their behaviors. Herein we describe a new object-oriented data model, with focus on its new notion of the dual inheritance which captures the “KIND-OF” semantics in context inheritance and the “REUSE-OF” semantics in content inheritance. With these new notions, the model exhibits an attractive flexibility in ameliorating the above problems.
