Study on applications of real-time database

A main memory data access technique that incorporates main memory database into traditional disk resident data is proposed according to the basic principle of real-time data base and internal data base. The application of this technique in data access object is implementd through repacking the interface between application program and database system. This makes the process of search and access possible in finite RAM without I/O of large number of disk data. The technique improves the execution efficiency of the application system.
