Many sophisticated computer applications could be significantly simplified if they are built on top of a general-purpose distributed database management system. In spite of much research on distributed database management systems there are only a few homogenous distributed database system architectures, that have reached the development stage. The situation with heterogeneous multidatabase systems, which connect a number of possibly incompatible pre-existing database systems, is even less satisfactory. To understand the complexity of designing a heterogeneous multidatabase system, we have presented some issues that have been a topic of research in this area. We propose a heterogeneous multidatabase system architecture which solves some of the inherent problems of heterogeneity such as reliability, semantic integrity, and protection. The heterogeneous multidatabase system environment that has been considered involves a connection of pre-existing database systems, with a possibility of adding new database systems at any time during system lifetime.
