What you will learn - II
 OMG - industry consortium. Defines
Specifications/interfaces for interoperable software
using an object-oriented technology
 Practical experience with an OMG/CORBA
implementation.
 CORBA (Common Object Request Broker
Architecture)
» standard architecture for distributed object systems.
It allows a distributed, heterogeneous collection of
objects to interoperate.
