The Common Object Request Broker Architecture (CORBA) is the Object Management Group's answer to the need for interoperability among the rapidly proliferating number of hardware and software products available today. Simply stated, CORBA allows applications to communicate with one another no matter where they are located or who has designed them. Object Management Group (OMG) introduced CORBA 1.1 in 1991. It defined the Interface Definition Language (IDL) and the Application Programming Interfaces (API) that enable client/server object interaction within a specific implementation of an Object Request Broker (ORB). The purpose of this project is to introduce the CORBA architecture, services, and IDL. I have built a system using Java based on CORBA to demonstrate its powerful client/server architecture.
