HLA仿真结果数据库设计及其应用研究

介绍了仿真结果数据库在HLA仿真中的重要性,阐述了数据采集的原理与数据文件的记录方法,分析了利用对象模型模板创建数据库关系表的过程。同时通过一个典型实例,分析了简单数据类型以及复杂数据类型的建表原理。针对HLA中数据完整性恢复的问题,提出了通过开辟内存恢复数据值以及基于数据库进行恢复的两种方法。接着介绍了数据加载和索引使用的策略。最后,对数据库中的数据,分析了剔除奇异值和数据平滑两种预处理过程及相关算法,并利用COGNOS商业智能软件进行了相应的处理。

Research on Design and Application of HLA Simulation Result Database

The importance of simulation result database in HLA based simulation is explained.A method towards the collection and recording of simulation data is put forward.The principle and technique of creating tables were analyzed based on Object Model Template(OMT).Besides,based on a representative example,the detailed process of creating tables was described using simple type data and complex type data.Towards the problem of data integral recovery in HLA,two different measures were brought forward.One is to recover data in preserved memory;the other is to recover data via databases.In addition,the strategies of loading huge amount of data and the management of indexes are presented.Finally,towards the data in database,two preliminary process algorithms of abnormal value elimination and smoothly data process were introduced together with the application of COGNOS business intelligence software.
