The Design And Implementation Of Prototype Banking System Based On SOA

Since China has opened the entire financial industry, the domestic banks face more complex and intense competitive pressure. In order to cope with this phenomenon, these banks have changed their IT systems one after another. The new system which is based on SOA basic thought put the service for customers as the primary purpose of the core business system. The banking system, which is based on SOA, can meet the demand of stability, flexibility and expandability etc, and also can satisfy the requirements of domestic bank business processing.After analyzing the bank classic business requirement and basing on the basis architecture, a prototype of banking system of SOA is designed and implemented in this paper. By applying the use case diagram, flow diagram and sequence diagram, the author analyze the designation of the SOA system's three layers. Moreover, several typical trades of banking system also has been designed in this paper, such as account register, deposit, withdrawal, reversed trade and end-of-day batch, etc. In order to ensure the stability of processing exceptional situation, a kind of asynchronous communication, which is named as "minor cycle response", is applied for designing the module of reversed trade. While in the design of the end-of-day batch module, the idea of "7*24 hour uninterrupted service" is proposed to guarantee the other business processing carried out smoothly.
