摘　　要：为解决企业间数据格式异构性 ,充分利用数据 ,提出了实现多企业数据查询的两种方法 ,统一数据库法和映射字典法 ,并分析了两种方法的优缺点。通过对企业产品数据模型进行分类 ,重点研究了映射字典法中两个企业间数据模型映射的分类与构造 ,总结出多企业联合查询实现的流程 ,利用 Windows NT环境实现了该功能。多企业联合查询的实现 。During operation of an agile virtual enterprise with independent enterprise units, the data transfer between units occurs in many formats so data is not easily shared. Two methods of realizing multi enterprise query, namely the unition mapped database method and the map dictionary method were suggested, and the advantages and disadvantages were analyzed. Classification of enterprise product data models was used to propose a method to exchange model data between two enterprises in the mapping dictionary method. The multi enterprise query process was implemented in a Windows NT environment. The implementation of multi enterprise query technology gives a powerful support tool for other application systems of an agile virtual enterprise.
