The Design And Implementation Of The Information Compare Technology For Shanghai Public Security Based On SOA

With the development and progress of the construction of modern police system in Shanghai, science and technology has been strengthened increasingly, especially IT application for Shanghai public security. How to make the information resource and system service practical work of the grass roots better, and raise the common policemen's IT application level further, is gradually becoming a great task claiming our constant attention. The information compare technology as one way of the information application, will be so widely used in the police work.After research and demonstration, this article focuses on the study design, an information compare system platform which is different from a traditional pattern for different application requirements. It adopts flexible compare modes to realize the information compare function between the different databases for the benefit of data mining at large. The system is propitious to know the object's activities and optimize intelligence analyses. It is based on large numbers of the information resource of the police operation. When the compare program run successfully, the system will show the result to users immediately.The system has SOA architecture, based on the use of ESB bus asynchronous communication mechanism. Various services could interact through the application of ESB reliable information and communication mechanism. The model analysis, data access, information compare and other services modules have been integrated together, forming a powerful, flexible, stable, reliable and scalable information system. The project designed an information compare metalingual and expression parser, which can achieve the complexity of the model function. In addition, the system can support a variety of databases and structured data. This subject of the innovative and advanced is mainly in three points. First, it's ESB-based SOA framework. Secondly, it's own information compare metalingual and expression parser. Thirdly, it uses the unified graphical configuration tool.In a word, this research is useful and advanced to support a variety of practical applications. This project was completed in 2008 through the acceptance of the Shanghai Municipal Science and Technology Commission expert group.
