Design And Implementation Of Approval Center Ledger Management System Of Postal Savings Bank

With the development of computer and network technology, the application of computers and network technology has been integrated into our daily work and life, and all kinds of office management software also allow businesses to run more efficient based on these technology. The development of computer technology strengthens the enterprise management and fully meets the needs of the development of modern enterprise. A lot of software about business financial management appear and provide great convenience. Through using the ledger management system, the enterprise improves the efficiency and is conducive to the cross-regional development.Firstly the paper has study about the present situation of approval center ledger management of postal savings bank of china, 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 system management, business management, workload management, ledger query management and report management. 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 approval center ledger management of postal savings bank of china.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.
