【Abstract】 In this paper, the middleware based on Object Request Broker (ORB)and Message Oriented Middleware (MOM)are introduced. CORBA works especially well as a distributed object model because it hides infrastructure and presents distributed programs and data as objects. Message Oriented Middleware is an excellent message transport. It enables asynchronous exchange of data,, event notification, persistence and quality of service (QoS). By combining the best of both technologies, an more reliable message services mechanism can be obtained.更多还原
