In this paper a semantic approach for the specification and themanagement of databases with evolving schemata is introduced. It is shown how a general object-oriented model for schema versioning and evolution can be formalised; how the semantics of schema change operations can be defined; how interesting reasoning tasks can be supported, based on an encoding in description logics.

Abstract
In this paper a semantic approach for the specification and themanagement of databases with evolving schemata is introduced. It is shown how a general object-oriented model for schema versioning and evolution can be formalised; how the semantics of schema change operations can be defined; how interesting reasoning tasks can be supported, based on an encoding in description logics.
