The Design And Implementation Of Workflow-based Credit Card Value-added Business System

Facing an ever fierce marketing competition, every commercial bank launches out various credit card value-added businesses. Hence it requires a flexible and systematic credit card value-added business system (CBS) process; in the mean time, it can increase system flexibility and boost development efficiency.Workflow technology can separate business flow from business rule; it also separate business data from flow-control data, which makes business management expediently and re-builds the business flow. By using this way, it enhances expansibility of information system, ameliorate and optimize business flow; plus it improves efficiency of business and achieves better business process control. In order to re-combine workflow smoothly, workflow management system harmonizes each activity within business processing through transferring and distributing related information and resources logically which is based on workflow technology.This article first discusses related information of workflow and main problems that credit card value-added business is facing at present. By analyzing from perspective of business changes and business workflow, I believe that CBS needs changes on supporting business workflow, separation of business data and workflow data and control of business workflow collaboratively. Meanwhile, I have further studied and analyzed the key features and core design of open sources workflow --- OSWorkflow.Based on this OSWorkflow, the article further describes the application design of CBS. I have expanded the data model of OSWorkflow, which includes the expansion of ACL data model, organization of data model, the supporting of sub-workflow and supporting of workflow procedure version control etc. I have also expanded the interface sockets of OSWorkflow according with CBS business. Later the article has researched and revolved the key features implementing OSWorkflow on CBS, which include application model of OSWorkflow on CBS, analysis of the relationship between OSWworkflow data and business data, refining the modeling method based on OSWorkflow and conclusion of application methods of OSWorkflow on information system.Based on theoretical research, the article combines the light weight workflow---OSWorkflow with credit card value-added business system (CBS) and coordinates the J2EE workstation and OSWorkflow plus with Spring, Struts, Hibernate and JSP etc to establish CBS. The whole CBS consists of several layouts, including data sustain layout, data access layout, business logic layout, workflow service layout, control layout and chart layout. By choosing typical CBS procedures like InBound process and OutBound process from workflow modeling to define and abstract business models, I have accomplished the key procedures. Meanwhile, this article also has introduced some core procedures about OSWorkflow on CBS realization, such as workflow implementing configuration, workflow initialization, and workflow inquiry.This article is an application research, combined with theoretical analysis, to finally design CBS. Currently the CBS has successfully implemented by one commercial bank credit card center, which has an average concurrent online users of 600. This CBS has supported over 40 businesses and a daily over 12000 calls. Finally through questionnaires from CBS developers, I have come to the conclusion that it is a well-structure system that has strong expansion capabilities and flexibility and can also increase working efficiency.
