An approach to schema integration between object-oriented databases

We have seen a significant growth in the number of implementation of object-oriented databases. Besides, there has been a need to access information from multiple data sources. The multidatabase system has been proposed as a solution for integrated access of data from distributed, heterogeneous, and autonomous database systems. To present a single database illusion to its users, a multidatabase system maintains a single global database schema, which is the integration of all component database schemas and against which its users will issue queries and updates. In this paper, we propose an approach to the integration of database schemas between object-oriented databases in a multidatabase system environment.
