Design And Implementation Of Public Security File Information Management System

With the rapid development of science and technology today,information construction of public security organs is very important,and improve the informatization construction is an important guarantee for the public security organs under the new situation in the fight against crime.Therefore,how to improve the information construction of public security organs,is placed in front of us to solve the problem.The archives management is the most basic and most important problem to be solved in the construction of public security information.With the development of information technology,archival computer information technology instead of the a large number of traditional manual records,the archives work of quality is more accurate,the efficiency of archives.According to the public security archives management department of current business processes and management status,combined with the characteristics of the archives information management system,points out the drawbacks of the traditional paper archives management,and puts forward the solution to the public security archives management system,to help police and improve public security archives management of the traditional artificial way to the main mode of operation,improve the grade and the level of archives management,to adapt to the current public security archives management modernization,scientific and simple,intelligent and reliable security management requirements,and make full use of computer storage,easy to find,easy to update,good secrecy,fast data processing and many other advantages for the file management services,improve the current lack of archives management and application the.This paper includes the following specific research and development work:1.In this paper,the main features of information management are first analyzed.according to file classification management of public security departments work characteristics,put forward the public security archives management system needs analysis,determine the system functions and business processes,use case modeling of system function module,system performance,security,hardware running environment of non functional requirements are defined.2.Using the B/S model for system architecture design,the advantages of using J2 EE technology,flexible client technology.According to the system design goal,the system software architecture,network structure,software technology solution are established.And the design of public security archives management system database E-R diagram,E-R diagram according to the database design,logical database structure in detail.3.The key technology of DES encryption algorithm,digital signature technology and Bayesian network are studied and analyzed.4.In order to prove the better system design and Realization of validity and availability,four aspects of the system functionality,performance,safety,reliability were tested found which there exist a few defects and give the right to repair,to fully meet the requirements of the specifications of the system,the full realization of the expected effect of the system.The public security archives management system has in my unit normal operation on-line,greatly improving the efficiency of public security work,public security officers to meet the demand of archives management.
