Abstract
It is shown that the concept of interfaces and the concept of composite objects are based on the same mechanism, an instance inheritance relationship. This relationship is integrated into an object-oriented data model which represents interfaces and composite objects in an easy way. The concept of interfaces is generalized to an abstraction mechanism. This allows some severe drawbacks of a rigid interface concept to be eliminated and generic component relationships to be neededKeywords
