Abstract:
Global acknowledgement of multi-databases has been made by the advancement in information and communication technologies. A multi-database system maintains a single global database schema which is the integration of all autonomous schemas located in a distributed environment. On the other side, the growth of object oriented databases has increased significantly due to the performance advantages they offer over relational databases. In this project, a multi-database system is proposed that use object oriented databases as underlying legacy sources.
Most of the approaches in the past concern with integration of relational database schemas. In this project, a complete system architecture for integration of object oriented database schemas is proposed. Each ODBMS has its own mechanism of storing schema, metadata, objects. Furthermore, there is no standard way of accessing metadata in each ODBMS. However, most ODBMS vendors have provided support for import of schemas from XML and export of schemas to XML. Thus conflicts between different ODBMS are handled through this facility. The underlying principle of my approach is to facilitate the automation of the system integration process.
