Schema Evolution and Versioning: A Logical and Computational Characterisation

In this paper a semantic approach for the specification and the management of databases with evolving schemata is introduced. It is shown how a general objectoriented 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.
