Building Flexible Enterprise DMS In SOA

The goal of this paper is to building flexible DMS in SOA system architecture.DMS are applied in automotive industry at domestic and oversea area.This paper is based on a practical project example of implement a enterprise DMS with SOA. Focusing on each stage of a special SOA system lifecycle, including services identification,services specification definition, service implement with web-service standard,building application programme and system example to invoke service's method. This paper has done a lot of thorough researches, and put forward a series of mature methods and technics.At first,this paper analyze the background and disadvantage of DMS applying in domestic market and point out these shortages will be keystone of the paper.Then,Many thorough researches have been done foucsing on SOA architecture and implement technics and methods.SOA is the most suitable solution to current DMS shortages because SOA architecture and related technics has much preponderance.On the SOA detail, this paper firstly analyze the normally four stages in the lifecycle of SOA and mainly tasks in every stage.According above result,this paper practise and examines the whole progress of fulfilling DMS.On identifying service in this paper, business goal decomposition and domain decomposition are be used.After decomposeing DMS all business goal and domain,the repair service business process is choosed as example.All of service in repair business are find and which consist of structure specification and conduct specification and strategic specification of all services is defined.However,the quality and management of service are take into account yet.Two IT service are defined to meet above need.The list of services can be writed and the list of web-service components which implement service also can be writed. Meanwhile,the developing environment and running environment are defined.Web-service components and DMS business application example will be completed base on these environment.The progress of implement a typical service:repair order step by step using web-service component is demonstrated.The progress is emphasis of this paper.In the progress,every detail of the web-service component are deeply analyzed which contains component coding and XML message setting and data modeling.Many valued ideas are given in the progress.On implement service and web-serivce component,the DMS business apllcation example programme which invoke the service's operation according DMS business logic is developed.Finally we implement a DMS application example to meet flexible DMS demand in SOA using web-service and we also research how the new DMS to get over those shortages above. In this paper, not only indicate the solution to solve crrent DMS applying problems but also analyze and pratise mainly detail methods and progress of SOA successfully. All of these are commonly helpful to other enterprise application applying problems.
