Design And Implementation Of The Management System For Criminal Investigation Files

With the reform process of" the rule of law ", in the process of the public security organs detect criminal, the requirement of the standardization and unification of legal files are higher than before. At the same time, with the popularity of the concept of "big data", the collection and management of criminal investigate files data, has also become an important part in the reform of public security informatization. Therefore, for criminal investigation files management methods, is bound to towards digitization and informatization office transition from the traditional manual work. Under this background, it is particularly important for the development of the criminal investigation dossier management system.Starting from the point of the view of the grassroots police officers, for meeting their needs actually, we describe the business of how the public security organ to manage the judicial documents and related investigate files. From the aspects of the role of the user, system function and system performance, the management system were demand analysis. Then, from the security and confidentiality of the data, this paper selects the C/S architecture as the system structure, the current popular Server SQL 2012 is selected as the database.In the system design stage, the main function of the system is designed mainly from two aspects of the function module and database. In the main function modules part, in this paper, we give the handling a case police information management, involving personnel information management, legal document template management and dossier management four parts of the detailed design ideas and business processes. In the database part, from the aspects of database model and database table, the design of the database is described in detail.In the system implementation process, with the principle of simple interface, operation clear, safe and secure, the system function module and database are realized. Finally, we use the method of black box testing, to test the system, from the aspects the link, the form, the database and the authority. We design the detailed test case, and carries on the test, the test results show that the system is running well and achieves the expected design target.According to the thought of software engineering, in the process of the criminal investigation files management system development, through demand analysis, system design, system implementation and system testing, the work are described, and gives the detailed chart information. Facts have proved that the development of this management system is very important to improve the working efficiency of criminal detection work.
