On Operations Along the Generalization/Specialization Dimension

The need to derive a database schema from one or more existing schemas arises in Federated Database Systems as well as in other contexts. Operations used for this purpose include conforming operations, which change the form of a schema. In this paper we present a systematic approach to establish a set of primitive conforming operations that operate along the Generalization/Specialization dimension in the context of Object-Oriented schemas.
