Smart data dictionary: a knowledge-object-oriented approach for interoperability of heterogeneous information management systems

Abstract

A hybrid approach is taken for the interoperability of heterogeneous information management systems. The authors combine the federated (unified/global) view approach with the multidatabase approach to provide access to relational databases, object-oriented databases, and spatial databases. Case-based reasoning techniques are explored to semi-automate the schema integration process. In addition, the incompatibilities among the information systems that cannot be transparently supported by the federated approach are resolved using attached procedures.<>
