| China UnionPay (CUP) payment service company's transactional data analysis system is one of the most important components of the company's global business information platform, which basic objective is to derive the characteristics and trends of payment business variations based on analyzing various ordinary transactional records and provide correctional data for erroneous events in electronic payments as well as to detect and recognize the risky events in order to enhance the banking card payment services' security and reliability.In this thesis the following works are accomplished with the abovementioned management objectives on the development of this software along the route of requirement analysis, design, programming implementation and tests. This payment transactional data analysis general functions are analyzed with specific functions in inter-bank transaction analysis, inter-nation transaction analysis and risk analysis are investigated in detail respectively with interaction and use case models setup for each group of functions, laying down the foundations for software designing. The system software design scheme is discussed with sketches in its general architecture and relatively detailed design descriptions in its major modules and database subsystem, setting up the database logic data organization and major object structures,, class diagrams, typical processing flowcharts and time sequence models. The system's implementation is presented with programming methods, its partial running information examples and its major tasks and results in test operations.This payment service company's transactional data analysis system is programmed with Java and DB2 database server in integration. This system operation has so far proved its capability to satisfy China UnionPay's new data processing and exchanging standards and technical standards for its platform management as well as to provide stable services to satisfy the development objectives with relatively good degrees. |
