The paper first introduces the composition of air-defense countermine system based on the DIS(Distributed Interactive Simulation). Then the principles,methods and technology pathways of building simulation database are discussed,distributed operation and dynamic process for database are explained. Finally,the concepts,methods and function structure of the database system management are given.%介绍利用分布式仿真技术开发的空防对抗系统的组成,并讨论了建立仿真数据库的原则、方法和技术途径,说明了对数据库的分布和动态操作的过程,并给出数据库管理系统的设计思想、方法和功能结构。
