DIS仿真世界数据库(SWDB)的原型设计与实现

从ＤＩＳ白方系统吉的仿真任务准备出发，研究ＤＩＳ数据库的结构和功能组成，并对ＤＩＳ的基本数据库－仿真世界数据库的结构和功能进行了深入研究，设计实现了原型。同时，在研究基于商用关系数据库系统的ＳＷＤＢ的层次结构实现中，着重介绍了基于关系模式的面向对象的实现技术和特性树结构的快速存储访问机制。

Designing and Implementation of the Prototype of DIS SimWorld Data Base(SWDB)

This paper studied the structure and functions of DIS database, based on simulation preparation in DIS management system. The paper mainly focused on the structure and functions of SWDBthe essential database in DIS, and put forward a prototype. We also research the realization of the hierarchy of SWDB based on commercial relation database system. The OO technology grounded on relation mode and the fast accessing mechanism of characteristic tree are the two main points emphasized in the paper.
