Analysis And Design Of Ratepaying Credit Grade Evaluation Management System

Ratepaying credit grade evaluation management is a classified management system by which tax bureau can evaluate the taxpayer for several different Ratepaying Credit grade according to the law and fulfillment of tax obligations of taxpayers. it can facilitate the improvement of credit information application level in management process, It can deepen State and Local collaboration, implements tax credit management scientifically and efficiently. Improve the service level of tax, implementation of the tax credit management, improve the tax service levels, it can also laid a solid foundation for the tax credit system specification development.The dissertation is based on the software engineering idea, uses UML modeling tools to analysis, design and implements the Ratepaying Credit grade evaluation management system. In the requirements analysis phase, the thesis introduced the system feasibility analysis, system business process analysis, role analysis, functional requirements analysis, non-functional requirements analysis, gave the system business process diagrams by UML activity diagram, divided system roles, and the function of the system is divided into system maintenance, evaluation management, dynamic management, integrated query, statistical analysis, completed the system functional requirements analysis by UML use case diagrams, and gives non-functional requirements of the system. In the system design phase, the thesis described the system design objectives, system design principles, system architecture design, system functional design and system database design, the thesis the physical architecture of the system, the system functional structure diagrams, UML class diagrams and sequence diagrams for each module, used E-R diagram method to complete the conceptual structure of the database design, and gave the date table structure. In the system implementation phase, gave the system environment and system interface design of the main modules.The system was installed and running well after developed, and it was well received by users, the system can be better to complete the tax credit rating all aspects of management. The system could complete all aspects of management of Ratepaying Credit grade evaluation management well.
