Design And Implementation Of Core Business System For China Citic Bank

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. Banks must take a positive attitude to face it as the first batch companies affected by the information technology. Through the suitable core business management systems banks can improve the efficiency. At the same time, the use of the core business system is more advantageous to the rapid development of the bank.Firstly the paper has study about the present situation of core business system of China Citic Bank, and fully analyzes the present situation of the current ledger management system design and development. Based on the detailed system requirement analysis, the ledger management system is mainly divided into individual customers deposits module, group customer deposits module, loans business module, payment business and same city business 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 core business system of China Citic Bank.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.
