Design And Implementation Of City Public Security Bureau Criminal Case Management Platform

City Public Security Bureau criminal case management platform is to meet the needs of our implementation of dynamic management and the fight against crime in the modern economic and social conditions, around the "strengthening the police with science and technology" construction target, follow the "overall design of Golden Shield Project", relying on public security network, based on work-flow technology, It is a criminal case management platform of using J2 EE architecture and Struts architecture. By implementing criminal case for the process of automatic control and enforcement procedures of supervision process, the platform has effectively enhanced the basic level of information of public security and law enforcement level of standardization.Through the investigation of police criminal cases handling procedures, the paper analysis the needs of various functional modules in the platform, designs the software architecture and the functional modules in detail and describes the database and tables design specifications and so on. As an example in some modules, it describes the implementation of system functions, and finally through testing the system, the test results achieved the expected goals. The platform can meet the requirements of practical use to handle criminal cases.The platform have realized the organic combination of business flow and information flow and also let the management and working platform became one.The system have achieved the handling of criminal cases online, realized the process of information management of receiving alarm?accepting and hearing the case?case filing?investigation of evidence?conclusion of investigation and detection. So it not only accelerated the process of handing the case, regulates the enforcement procedures, but also shortens the processing time for cases reviewed and saves police resources. At the same time, the platform adopted three layer architecture which based on J2 EE specification,it separated the presentation logic?business logic and data logic.It greatly improved the system ability of concurrent operation ?network computing and extensible.The client-side uses the browser mode, so it has realized the real zero client. It satisfied the large management system on the system stability,security and sociability requirements. Overall, the system has designed fully functional reliable?practical and easy to operate, so it has a good prospect and popularization value.
