What is a CORBA-based application? Shortly, it is a complex application comprising several distributed parts. This parts communicate together by using a Common Object Request Broker Architecture ([OMG98a]) conform implementation. CORBA allows a developer of such an application to achieve his tasks without considering: distribution, different languages, network protocol, and so on.
