A MDBS (Multi Data Base System) is a system that provides access to data from a collection of DBSs (Data Base Systems), called component DBSs, that are heterogeneous and distributed. The integration of the component DBSs into the MDBS is performed by a complex of functions termed gateway. This paper describes the design of a gateway based on the distributed object computing (DOC) approach, and compliant to the CORBA (Common Object Request Broker Architecture) standard. The approach is shown to introduce savings in design complexity and cost. The details of the approach are described in a gateway case study for the integration of a relational DBS into a MDBS.
