Design And Implementation Of SOA-based Financial Bank Card System

Financial industry is one of industries with higher level in domestic and overseas ITapplication fields. Widespread use of IT in financial banking sector not only brings profoundreform to traditional operating management, but also impacts interactive use habits withbanks. Meanwhile, banks devote their efforts to develop this retail business. Nowadays,commercial banks at home and abroad have already developed into connotative developmentof abundant business varieties and enhancing earnings rate from volume. This providesconditions and possibilities for establishing bank card system. Introduction of SOA ideamakes traditional core system established by most of commercial banks at home and abroad isabout to be encountered with a new round of wave to optimize and reform system architecture.Thus, it brings a new challenge to bank operating department, technological department andsettlement and reconstruction of operation management. It also reinforces interaction andcommunication and coordinated management between business personnel and scientific staff.According to the characteristics of a certain commercial bank and by combining withbank card business requirements and study on design idea of service-oriented architecture(SOA), the paper conducts demand analysis on system functions and designs a bank cardsystem based on SOA. The designed system plans to adopt C/S three-tier architecture designmode, including application of bank card, accounting disposal of bank card, bank cardmanagement and information inquiry of bank card, etc. system function modules. Meanwhile,this design realizes the integration of system service functions in accordance with SOA.Overall application model of this system conforms to future development direction ofinformation technology for international commercial banks.Hierarchical division of thissystem structure is distinct. Independent function module design is equipped withcharacteristics of advance, safety, balance and expansion.The essay according to the commercial bank card business process, analyze the bankcard business requirements, based on service identification process, analyze of the whole bankcard business demand function components, services, process identification, according to thefeatures of business,identify the main service and the corresponding component,makes theservice embodies the loose coupling very well. On the basis of financial bank card system forcomprehensive analysis and design,the essay gives the overall structure of the system designand database design, introduces a method to implement the components of the system andservice as well as the system test case design method and corresponding. The system is built on the IBM host on the Mainframe platform, the structure of the system stage isclear,after the implementation of the system,the whole operate smoothly, the performanceachieved the expected goal.
