Recent years, material support information becomes more and more important with the development of army information.During the process of realizing army information, many Equipment Support Information Systems are developed, but those information systems are isolation each other, with short compatibility and interchangeability. Therefore, it is time to implement the data integration and uniform mode view though the data maybe come from different departments. We can make the equipment support policy and distribute the support resources by doing that.Based on analyzing the main integration technology in the field of data integration, the system configuration of integration environment for equipment support information is designed combining with the advantages of middleware technology and data warehousing technology. The method of software engineering is used for reference while designing the integration environment and the iterative increment method is used to analyze, design and implement the integration environment. The main works of this paper are as follows:(1) The class and composing of equipment support information are analyzed, furthermore, integration frame and integration method are studied.(2) Several key technologies of equipment support information integration environment are studied, and a schema matching method based on combination competition relation is presented in the thesis. Based on these technologies, the mapping is implemented to select effective matching support by extending hyper graph data model and the inner constraints of schema. What's more, the query of target schema is decomposed to the query of source schema using effective mapping rule, and the query result is incorporated as final query key.(3) Module composing and integration process model are designed in this thesis. The key techniques are presented and the main kind figure, sequence chart & flow chart of key function are proposed. Furthermore, the data integration environment is designed and developed.At last, a example is proposed to demonstrate the method of this thesis. The equipment information databases from different departments are used as heterogeneous data sources. The equipment statistics is accomplished by equipment support information integration environment.
