Using Middleware for Interoperable Systems

The increasingly distributed nature of business locations and operations has led to a concomitant expansion of client/server computing from the department level to the enterprise level. Yet the successful implementation of client/server, or distributed, business applications depends on interoperability&the ability of applications to work together across a network to perform business functions. Systems integrators need to know exactly how a client application will talk with a server application before either can be designed or written. If they do not, unrealistic assumptions about appli- cations-Ievel connectivity can be project killers.
