| Abstract: | There are vast and complicated data in the simulation system. USing database to manage these data is benifieaial to the extensibility and modularized design of the system. The development and application of CBTC simulation system are described briefly. The application of the database in CBTC simulation system and its design principle are introduced. And this paper mainly illustrates the way of database design by use of object - oriented method. The translation of simulation system object - oriented data modes, expressed by conceptual models and independent to DBMS,into the SQL server data modes is discussed. The problem that complicated data structure in CBTC simulation system is difficulty to design has been solved. It meets all requirements of the database design and is worth further researching. |
