Build practical real time information system in a digital enterprise

It is very important in the implementation of digital enterprise that is how to build a reliable data source from control system or the others. We describe the design and implementation of a practical real time information system in digital enterprise, the main topics of this paper are the main architecture of such system and it´s features, real-time data transition and store and forward mechanism for data integrity. We´ll talk about the concepts, device object modals and implementation methods of some real software modules in the system. The system mentioned in this paper was finished and applied in the efficiency analysis system for power plant.
