Police Safeguards Systems Analysis And Design

With the continuous development of science and technology, development and popularization of computer technology, computer network technology becoming more closely linked to people’s daily lives. Information technology has gradually developed into supporting cornerstones of life in today’s society, and represents the development trend of advanced productive forces in society today.Fixed in existing networks, supported by information technology, through the building of effective information management systems to improve the Government’s work efficiency, reduce Office expenditures, providing high quality and convenience of the public service. In this paper, the daily work of police protection for the study, starting from the actual, analysis of the current problems in the material management, combined with the development of management information system of the fundamental principles, design a policing and security system. First of all, this article studies the police material inventory management, analysis of material management feature which details the basic content of material management, extracting material management decision problem. Second, the detailed system development mainly includes requirements analysis, system design, database design.Needs analysis, from the system’s business requirements, functional requirements, data requirements, non-functional requirements described four aspects; system is designed from the perspective of abstract concepts and functional requirements, the logical model of the system according to the demand structure, and through case analysis and concept analysis in detail; in introduced the concepts of database design, database design and data dictionary. This article first to study police security management, analysis of the context of police security management features, a detailed understanding of current problems in the information system, analysis and abstract the details of your business requirements, non-functional requirements were discussed. System needs to be based on a full range of design, through means such as flowchart, ER diagram, use case diagram, addressed to system functionality.Finally, summarizes the research work of the system, pointing out that shortcomings in the analysis and design.
