In industrial production, on the one hand, to maintain a Shared data and control data, On the other hand, the applied activities have strong timeliness. So, this application is needed to support the massive database data sharing, maintain the consistency of the data, and need to support the real-time tasks and data regularly However, the traditional database system to handle the data stability, permanent, emphasize the integrity of the data consistency, maintenance, without regard to the relevant data and the processing time limit. The traditional real-time systems support the task in time limit, but it is very simple, the relationship between structure and stable and forecast data, does not involve a Shared data and maintain the integrity and consistency Therefore, only two concepts, techniques, methods and mechanism of seamless integration real-time database can also support the timing and consistency. However, real-time database is not database and real-time system, it is a simple combination of both the need for a series of concepts, theory, technology and method and mechanism research, and to make each function module design of considerate detailed
