....[DH84, Mot87, MNE88, Bra93, SGN93, TS93, KS95, NS96] They usually resolve this conflict directly in an object oriented model by using specialization. The original classes are often classes of the integrated schema enriched by new super subclasses and specialization relationships among them. DS96] for example, suggests many operations to resolve a conflict between two classes. Problems arise, however, if two specialization hierarchies with many classes need to be integrated. The mentioned approaches generate in this case very complex schemata. Furthermore, different variants of conflict ....

....1 Introduction Schema integration [1] is one of the central issues in logically integrating database systems [6] Schema integration aims at deriving an integrated schema which is a virtual view on all database classes to be integrated. Traditionally, all existing schema integration methods, e.g. [4, 7, 3, 2, 5], assume that the database designer as integrator is an expert of the application domain who has complete knowledge about the semantics of the schemata to be integrated. Thus, the database designer should be able to exactly define the extensional relationship between two classes of different ....
