The Design And Implementation Of Net Tax On Bank

With the process of electronic construction in commercial banks accelerated and the financial products continually launching into the market, all commercial banks expand intermediate business swiftly on the basis of traditional asset and liability business, which makes the intermediate business gradually become a new beneficial growth point. In 2004,the People's Bank of China Tianjin Branch started to set up the Finance-Tax-Custom-Exchequer-Bank System. With this turning point, Bank of China Tianjin Branch designed and implemented an intermediate product-the web base tax payment system according to its conditions and the requirements of Exchequer-Bank-System on the basic of the original web based tax payment businesses.This article makes an in-depth analysis and explanation about the'web based tax payment'from the proposal of the design plan, demand analysis, master design, detailed plan, accomplishment and system test. Meanwhile, this article divides the whole business demand in three levels: gateway messaging, web based tax payment businesses process and bank accounting process. It also develops the process module of gateway platform, web based tax payment platform and customer service platform in order to fulfill the corresponding functions.On the gateway platform, we fully utilize the distinguished qualities of IBM Websphere MQseries middleware, its cross-platform and integrity of transmission. We achieved forwarding functions of transaction on the gateway platform by combining the programming interface from the IBM Websphere MQseries. Meanwhile, we probe into using signal mechanism of UNIX platform to maintain the program long-term stable running. On the web based tax payment process platform, we give detailed explanations of the process flow in web based tax payment business and accomplish the message transmitting to gateway platform by means of MQ Datagram. In the communication with the customer service platform, we still adapt the traditional Socket way. We also study multi-threaded and thread control in Windows platform. When planning and implementing the process module on customer service platform, we highlight the research on how to ensure the consistency between bank accounting host data and the local data, and how to implement the processing of web based tax payment at night and in red-letter days when the bank accounting host closes outward services. We design a uniform external interface that not only supports the web based tax payment system but also establishes a solid basis for developing other bank systems in the future.
