Design And Implementation Of Digital Certificates Management System Of BinJiang Road And Bridge

With the development of computer and internet technology, the application of computers and network technology have a profound influence on the daily operation. The developments of computer technology facilitate the development of group and fully meet the needs of the development of modern enterprise. Through the suitable digital certificates management system the BinJiang road and bridge engineering limited company can improve the efficiency. At the same time, the use of the digital certificates management system is more powerful to guarantee the safety of the companies.Firstly the paper has study about the present situation of digital certificates management system, and fully analyzes the present situation of the current digital certificates management system design and development. Based on the detailed system requirement analysis, digital certificates management system is mainly divided into receive information module, certificates information module, warning management module, system information module and auxiliary management module. By using unified modeling language on the system modules and system as a whole to dynamic and static modeling, including the design of the system use case diagram, class diagram, flow diagram, sequence diagram. These work make us understand the system more accurately and more reasonable for system design, and ensure system modular design, and more effective for system integration. This project fully realizes the functions of each module, meets the users'requirement, ensures that the system can be efficient, safe and stable, and lays a solid foundation for the modernization of digital certificates management.Through the black box this system has a large number of test cases. On the basis of fully tested, all bugs found in the testing are analyzed at the code level, made a comprehensive revision and ensure that the system can meet the needs and provide safe and efficient service. In addition, through a lot of testing work, the system has fully meet user requirements on function implementation, prove the system has been able to meet demand and get the correct implementation.
