Information Integration And Modelling Research Based On Metadata To The CIS Of CAPF

With the development of information and network technology, to construct an information army has become one of the most important subjects in the process of army modernization. At present, the information construction of CAPF has achieved a certain level. The CIS of the operational control center is the important strutting platform of command informatization. The service IS connected with the direction IS is distributed in command, politic and logistics departments. Due to the difference of the development time and facility and operation environment, and the diversity of Metedata model, there exists isomery between each IS, which obstructs information sharing and exchanging and isolates information, causing the phenomenon of "Information Isolated Island". Thus the information integration of the CAPF's CIS has become an urgent subject in the army.One purpose of informatization is to realize data-sharing, and another more important one is to achieve the sharing in Metadata level, i.e. semanteme sharing of information. Therefore, integration technology based on the Metadata has become a popular method in the IS integration research filed. In view of the above question, this thesis summarizes the IS integration development, the present research and the main method, and then proposes information integration technical route based on Metadata. This thesis analyzes the integrated model, gives a detailed design to various services data connection in the system and provides models and views in every plane based on the Wrapper/Mediator middleware technology. It designs a Metadata regular database and provides the strategys for Metadata management,mapping and memory. Finally this thesis designs the CIS information integration frame and gives an account to the main functional module and the essential technology of the system through demonstrations.
