Design And Implementation Of Rent Credit System Based On SOA

In recent years, the service-oriented architecture (SOA) has been developed fast. It is one kind of loose coupling software architecture which can reduce the coupling degree between service providers and requesters. The service requesters will not be influenced when functional modules are used in this structural design system as long as the module service interface does not change even if the detailed implementation of the module changes. Therefore, the Rent Credit service System (i.e. RCS) based on SOA is designed and implemented in this paper.First, the background of RCS and development of SOA is studied and analyzed, and the feasibility of constructing the RCS based on SOA is illuminated.Second, the basic knowledge and related technology of SOA and Web service are analyzed, SOA is implemented by Web service and Web service of RCS is implemented by .NET. In this foundation, the overall framework of RCS based on SOA is proposed, functional and database modules are designed, and the main function structure charts and tables of RCS are provided.Third, a service framework based on SOA is presented and the services involved in the whole system are divided into three modules: renting entity management services module, renting business management services module, renting external interface services module.The services in each module is defined and services in the RCS are developed by .NET technology,the implenmentation of services in detail is illuminated and some key codes are provided.Finally,the performance of RCS which takes renting net as the example is analyzed. Results show the RCS based on SOA can totally achieve the demand of renting business. Now this system has been operated in KaiHui information service company and performs well.
