  Abstract

Recently, most of global enterprises have geographically distributed organizations, thus have distributed information systems which have distributed database systems. So, it is difficult for these systems to provide common views for the application programs of end users. One of solutions to solve these difficulties is an MDBS(Multidatabase System). A method to effectively implement MDBS is a schema integration. This paper proposes a methodology for a schema integration through extraction of common similar subschemas. Our methodology is consisted of 5 phases : affinity analysis, extraction of similar subschemas, decision of integration order, resolution of semantic conflict, and schema integration. To verify the usability of our methodology, a case study is implemented with an object of MDBS. As a result, our approach can effectively be applied to the extraction of common similar subschemas and schema integration.
