Active Mechanism To Support System Simulation Database Technology

This thesis introduces thoroughly the main contents of research and development on the active梤ule database system.Real-time performance and interation performance are the two targets of the computer' s simulation technology. Arm at the high request of the System Simulation,a new approach is put forword. Namely梩he technology of active rule database. The method can monitor dynamically data of backend corporate database and manage them ,relying on the technology of active rule, then structures an active database management system.The paper first introduces the concept of ADBS and introduces some topical systems. Then discusses the design idea in detail in such topics as definition of ADBS, denotation of the rule, memory structure of the rule, disposition of the rule, etc. Finally, according to the design idea of the active database, the paper chooses a practicality application system PCS-DBS (Flight Control System-Database system) to testify the validity of conclusion.
