Memory Database Technology Support System For Simulation Study

With the development of computer technology and the change of CS (Computer Simulation), the appearance of DIS (Distributed Interactive Simulation) and HLA (High Level Architecture) change the pattern of CS' s research and application. Aim at the high request of System Simulation, a approach to data management that greatly improves the performance of real-time is put forward. Namely, the technology of MMDB (main memory database) is used to satisfy the demand of real-time performance. The method can cache data of backend corporate database and manage them relying on the technology of main memory database, then structures an in-memory relational database management system.The paper first analyses the traditional database, their advantages and drawbacks, and gives the concept of MMDB, then discusses the design idea and implementation in detail in such topics as definition of MMDB, design of system front plat, management of main memory of system backend database, memory structure, recovery mechanism, etc. At last, the paper chooses a practicality application system PCS-DBS (Flight Control System-Database system), and uses the example to testify the validity of conclusion.
