Complex System Of Data Integration Technology Research

The direction of integrated joint operations is continually appeared in large complex system. The application environment that composed by most of the isomerous system, application, operation flow and data source already could not satisfy such requirements. so it urgently require build integrated and sharing data environment for large complex system, and establish integrated and unified military information data source system, to realize information sharing and data flowing between systems orderly.Firstly, the research status of data integration in our country and abroad is depicted. Then, according to the benefits and disadvantages about the current data integration technologies, and the character of large complex system environments as well, a common ETL system is provided. Which has many characters: common technology of data accessing,friendly user interface ,abundant data verification,data cleaning,data transformation functions and management of mete-data repository.The mete-date repository provides strong support for the management and control of ETL process,and enhances the flexibility and expansibility of the ETL system . The establishment of data-prepare-area can implement some complex transations.The agent manage the data flow, and can support more DBMS.The graphics managment tool is separated from the transaction services, which support another applications.The design and implement of this system is completed in the article. At the end of article, a experiment is given.
