On Interface Objects In Object-Oriented Databases

This paper describes an approach to the support of interface objects in an object-oriented database, and outlines some of the consequences of representing interface data as database objects. Existing architectures for implementing database interfaces are reviewed, and certain shortcomings identiied, which essentially stem from an impedance mismatch between the database and its interface. It is shown how an existing graphical component set can be cleanly and transparently integrated with an existing object-oriented database, thereby removing the above impedance mismatch and providing persistent graphical data. This interface can then be used to implement generic, tailorable and application-speciic interface concepts, each of which is exempliied in the paper. a
