| Abstract: | Data-base system has taken more important part in simulation system,which is applied in many areas.The functions of Data-Base and the peculiarity of data that satisfy system demands are discussed in this paper,based on the work flow and structure of the distributed real-time simulation system used in spacecraft simulation.Thus,the Data-Base is divided into three parts: Model DB,Scenario DB and Test DB.Then the O-O technology is adopted to design and implement the Data-Base prototype.At last,some brief scenarios for performance optimization of the DB in design process are given. |
