摘要
为克服传统的HLA仿真数据库基于关系数据库开发、数据对象的结构及相互间关系需在设计阶段指定、一旦开发完成、存在数据模式难以修改和扩展等缺点,基于HLA仿真数据按面向对象设计的特点,研究了利用对象关系数据库技术开发结构可灵活扩展的HLA仿真数据库的问题,提出了基于HLA对象模型设计、实现、管理和使用可扩展的对象关系型仿真数据库的技术方法。应用于作战仿真领域的实际系统中,结构可扩展的对象关系型HLA仿真数据库在使用和维护上更加灵活、方便,适于HLA仿真领域的高级数据库应用。
The traditional HLA simulation databases are mostly developed based on RDBMS by now, the structure of data objects and the relationship among them need to be well - defined in the design phase, and once implemented, some insurmountable shortcomings may emerge, such as the structure＇s inextensibility. The extensibility and flexibility of simulation database is an important issue in HLA simulation data processing applications. Therefore, based on the feature that the design of HLA simulation data is Object - Oriented, this paper explores a method to design and develop an extensible HLA simulation database by using the object - relational database technique, and provicles the solution based on HLA object model to implement, manage and use the extensible object- relational simulation database. The method has been applied in warfare simulation applications, and the structure＇s extensibility of object - relational HLA simulation database brings more flexibility and convenience in using and maintaining it. So it is applicable for the high - grade applications of database in HLA.
