As technology seems to transform businesses and markets overnight, Information Systems must provide the same flexibility and adaptability as the companies they support. Companies must maximize the strengths of the traditional mainframe stability, manageability and performance — while integrating them into the openness and interoperability of distributed networks.
One of the chief challenges of mainstream client/server implementations, is certainly the integration of client/server with the existing network of systems and applications to better enable communications… Simon Systems has the experience and expertise necessary.
