Schema refinement and schema integration in object-oriented databases.
Chris J.E. Thieme, Arno P. J. M. Siebes · Data Archiving and Networked Services (DANS) · 1993
This report presents a formal approach to support schema integration in object-oriented databases. The basis of the approach is a synthetic subclass order to compare classes. Classes are integrated in a natural way using a join operator w.r.t. the subclass order. In contrast with existing literature, our subclass order compares classes not only by their attributes, but also by the behaviour of their methods, leading to a more semantic approach towards schema integration in object-oriented databases. 1991 CR Categories: D.1.5: [Software] Object-oriented programming, D.2.2: [Software] Tools and techniques, H.2.1: [Database management] Logical design.
