On schema integration in a heterogeneous distributed database management system

Abstract

An approach to schema integration in a heterogeneous distributed database management system (DBMS) design is described. The approach has been used with success in a prototype multiple database access system (MDAS). This system acts as a front-end to multiple local DBMSs which continue to perform all local data management and processing. The MDAS services queries on an integrated view of semantically related databases exhibiting a range of schema and data conflicts.<>
