Research And Realization Of The Credit Card Information Management System Based On OAF

With the rapid development of Credit Card business, the involvedmaterial is getting more and more complex. This means a well-designedmanagement system is quite necessary to realize effctive resourceadministration. Due to the lagre scale of the system and the complex userlogic and meanwhile limited time schedule, ZERO start method isimpossible and software reuse is the only way out of this. At present, theindustrialized software reuse has been developing from calling thecommon library to using the domain oriented application framework. Theapplication framework reuse has become one of the most effectivemethods in software development. According to the above background,OAF(Oracle Application Framework) based B/S pattern distributedmulti-layer architecture system solution is put forward to the Credit CardInformation Management System.In this paper, design patterns and MVC(Model-View-Controller) areintroduced first. J2EE MVC2 truss and software framework technologyare also presented. OAF architecture is then deeply analysed. In thefollowing, the overall design of the system and the detailed realization aremainly introduced. Under the direction of system requirements, designprinciples and business flow is identified and the whole system is dividedinto eleven function module. B/S pattern multi-layer system architectureand frameworkbased software development method is analysed. The wayof data processing and database design principle is confirmed anddatabase table and dictionary are designed. Taking credit card printmaterial information updating module for example, the detailedrealization of the system is then explained using the combination of textand program code. Some key performance assuring techniquesimplemented in the system including security policy, data accessingoptimization and exception handling are also discussed. Finally theresearch work is summarized and the future work is discussed.This paper introduces OAF based development with real projectdevelopment experience. It provides practical guidance and reference onframework based software development using MVC architecture.
