The Research On Synthetic Query And Data Integration Platform In The Frontier Army

This thesis is based on a real project of Guangdong frontier defence army.After many years development of information systems, a lot of applications have been deployed and a large number of datas have been collected. But because of many systems are designed and deployed stage by stage independently, a phenomenon called"Informtion isolated islands"appears. The datas can not be shared by different applications. On the other side, current applications just focus on business flow but lack of decision functions.To resolve above problems, the key techonogy in synthetic query and data Integration platform of heterogenous databases is researched in this thesis. Firstly the business datas in different applications are analyzed and abstracted into"five-key- element model"including person, case, article, place and organization, the data organization schema based on"five-key- element model"is created. Secondly the data integration model using the middleware technology is created. The model can be easily fine-tuned for new usage, and it is plug-and-play. Finally the core section of this platform, the"querying engine"is analyzed and designed.This thesis designs and completes the synthetic query and data integration platform in the frontier army which provides the information exchange and data integration function, the synthetic query beyond business, area, system platform is achieved. Based on this platform, the deeper applications such as contrast alarm and data analysis are also achieved. The datas are shared more effectively.
