What is an Object server?
With an object server, the Client/Server application is printed as a set of communicating objects. Client object converse with server objects using an Object Request Broker (ORB). The client invokes a process on a remote object. The ORB locates an instance of that object server class, invokes the requested process and returns the results to the client object. Server objects must give support for sharing and concurrency. The ORB brings it all together.
