Abstract:In this paper, an architecture frame model of command information system assembles and integration was established based on the methods of Domain Special System Architecture (DSSA). Furthermore, the design idea, general structure, and key technology of the model were introduced. At the same time, problems of both the compatibility on multi-systems technology and the manipulating & data-exchanging among different components were resolved, by means of the objective conversion agents and the bridging technology of communicating objective model, respectively. As a result, the model is feasible for integrating large-scale command information systems, and is useful for similar information system.
