The CORBA specification defines two mechanisms for implementations of a CORBA Object to service its operation invocations. One is the static mechanism and the other is dynamic. The static mechanism requires that the implementation support the specific methods as required by statically KNOWN IDL INTERFACES. Implementations can do this through either a delegated or derived approach (i.e. inheritance or delegation/TIE). If the dynamic approach is taken, the implementation of the Object deals with the REQUEST generically and in a sense, has one "do-it" method for dealing with all requests. The implementatin must INFORCE type safety as apposed to RELYING on an IDL compiler or Language compiler to do it. DSI is much more complicated for a developer then relying on the IDL compiler to generate static request dispatching code.
