Data Sharing, Schema Mapping, Database Middleware
Schema Integration is one of the most difficult issues in
the heterogeneous and Distributed Databases Systems.
The integration and sharing of information has become a
crucial task for the organizations and decision makers.
Database Middleware Systems have become a highly
desirable and important technology to tackle this problem.
But, one of the main problems faced by system
administrator for middleware systems is that there are
very few tools for catalog management and schema
mapping management. Most tasks are done manually, and
it is often necessary to write some ad-hoc code to make
any change in the global schema. This research attempts
to provide a solution to tackle such problems. The
research reported in this paper describes a schema
integration methodology and prototype tool that interacts
with the administrator and suggests possible actions to
help the administrator to efficiently manage the catalog
and accomplish the integration and sharing information.
