Reacher Of Real-time Database System Based On Process Control

The real-time database is a kind of special database which its data and transaction all has a real-time limitation, and mainly applied in all kinds of time key application. The process control is a extremely important application situation of real-time database, it mainly processes the production installment, the production process control and the optimization, production system schedule, and in the modern enterprise, it is the important part of the Enterprise Information Integration System.This article analyzed the demand of real-time database based on process control, proposed one kind of object-oriented real-time data model, and has further produced the object-oriented real-time transaction model in this foundation by Object-oriented method, further more, it analyzed the priority assignment and the transaction schedule as well as the concurrency control method. Then has realized a DLL form real-time database system initially using the VC platform.After the test, uses the memory database mechanism the real-time database system to compare the tradition relational database system to have is not in magnitude fast reflection ability can satisfy the process control to the data real-time processing request.
