CORBA
In what respects did CORBA seek to improve on technologies such as SunRPC?
Expert
As SunRPC is Language/OS (Unix System V, Linux, BSD, OS X) dependent where CORBA seeks to have an RPC which is Language/OS independent.
The SunRPC do not provide polymorphism (Object oriented languages expect polymorphism where services may behave differently based on data types passed to it.) where CORBA seeks improvement.The SunRPC do not provide dynamic invocation where CORBA seeks improvement.As with SunRPC, we need a unique program number per server while as CORBA seeks to have an RPC which provides to generate unique ID.
