We hope that through the establishment of institutional credit code system, to focus on the financial sector as a whole forces together to solve the difficult problem of institutional client identification.The paper introduces the research background of institutional credit code, description of the problem, the significance of the study, the design goal of the system. In the requirements analysis phase, we give system business analysis, given the system operational framework diagram, the functional requirements of the system analysis, the system function module is divided into data acquisition, institutional credit code management, institutional credit code query, statistics management, message management, system management, and in each module we give the use case diagram and use case Statute, at the same time we give the non-functional requirements of the system. In the system design phase, the paper gives the overall system design, system features modular design and system database design, in the overall design we give system design principles, system architecture design and system functional architecture design, in the system features modular design phase, we gives class diagrams, sequence diagrams and collaboration diagrams of the six main modules of the system, described the contents of each module design, we give the concept of data structure design and database logic structure design, system database design E-R diagram and table structure. Finally, we give my main work in the study, point out shortcomings in the paper, and the prospect of further work. |
