6. Core of CORBA: OMG OMG is responsible for defining CORBA OMG is an association that previously aimed at setting standards for distributed object oriented systems. Now they focus on modeling programs, systems, business processes, as well as model-based standards

7. OMG More The OMG comprises over 700 companies and organizations. Currently, three types of techniques are used in the object-oriented middleware arena: Microsoft’s COM+, Java RMI from Sun Microsystems, and CORBA from OMG.
