Research On Database Middleware In HJ Combat Command System

Database middleware is the middleware that all of the most common and most mature one. Database middleware allows applications with local or remote database to communicate. Based on the development of middleware basis of the application system Application development will bring great convenience, reduce labor intensity of the developers will also examine how to improve the system stability and easy maintenance, and reduce the number of concurrent users ,also share some of the Database work. With the database middleware technology expanding of the scope of application higher and higher performance is required. So real-time is introduced in the database middleware. It requires the operation of the database within the required timeframe to complete. The author studied the real-time database middleware in the background of a project of participated.Here we introduced the design of SERI_DB middleware background HJ combat command systems. We first analyzed the SERI_DB middleware in its system work and features, and then introduced the design of middleware involved in theory, cache memory technology and database technology; Followed we detailed the SERI_DB middleware in its architecture ,and the function of each component part; And also we elaborated the realization of some components.Finally, through a test system with the SERI_DB middleware to prove the correctness of the SERI_DB middleware, the stability of the system and its response time than traditional methods of database access has better control.
