Design And Implementation Of Interest Rate Management System Of Postal Savings Bank Of China

Since entering the new century, information technology represented by computer and internet develops rapidly, constantly extend and expand to every domain, and has a huge role for the development of various industries. Especially in the financial field, design and implementation of various management systems improve the efficiency of all kinds of business, and meet the evolving requirements for banks and the increasing user demand for business. The information technology provides the best tools and instruments for the operational management of the bank.Firstly the paper has study about the actual situation of postal savings bank of China, analyzed the situation of the design and development of the interest rate systems. Combined with the postal savings bank’s own business needs and the situation of the software and hardware, the system is divided by modular in accordance with the overall function, and mainly divided into system management module, rate monitoring module, interest rate analysis module, parameter management module and report management module. For achieving more comprehensive information, software engineering technologies are adopted to model the system. Unified Modeling Language is used to model the system from the overall system perspective and the perspective of the module, including the system use case diagram, flow charts and class diagrams. In addition, in order to ensure that the system can work efficiently and stably, a large number of test cases are designed to fully test the system. All bugs found in the test are analyzed deeply and reasons are found, and the error codes are modified. All bugs are solved. And interfaces and user experience are optimized to ensure that the system can meet the needs of users.The overall system design and functions have been realized perfectly. This ensures that the system is fully realized design requirements to meet the needs of users and also prove that the system has high stability, accuracy and security. The system is designed to achieve an important step in the informatization of postal savings bank management system and laid a solid foundation for the future development.
