摘　　要：简要介绍了通用雷达装备虚拟维修训练系统。针对系统存在的不足,根据XM L数据库与关系数据库之间的映射方法,提出了基于XM L Schem a,对XM L数据库进行数据存取的思路。从XM L Schem a描述VC++结构出发,解析XM L数据,利用XM L转化成DOM来对数据进行存取,并提供了一个具体实例。对虚拟维修训练系统置于广域网跨平台进行异构数据操作的开发具有重要意义。The virtual maintenance and training system for general radar equipments is introduced briefly. Aimed at the weakness the current system exists,a method for XML database of data access based on XML Schema is proposed, according to the mapping between XML database and relation database. In this paper, it is illustrated in the way of VC＋＋ based on XML Schema and parses XML data, which can be accessed from DOM transfromed from XML. An instance is given here. The efforts this paper made have the vital significance for the development of this system that is put into Internet to operate the data from different structures.
