CORBA
The Enterprise Server supports a standard set of protocols and formats that ensure
interoperability. Among these protocols are those defined by CORBA.
The CORBA (Common Object Request Broker Architecture) model is based on clients
requesting services from distributed objects or servers through a well-defined interface by
issuing requests to the objects in the form of remote method requests. A remote method request
carries information about the operation that needs to be performed, including the object name
(called an object reference) of the service provider and parameters, if any, for the invoked
method. CORBA automatically handles network programming tasks such as object
registration, object location, object activation, request de-multiplexing, error-handling,
marshalling, and operation dispatching.
