Research And Application Of Mid And Small Enterprise ERP Architecture Based On SOA

Service-Oriented Architecture (SOA) is a new generation of architecture ideologyapplying for distributed software development. SOA has solved the problems ofapplications for flexibility and interconnectivity wonderfully because of its features ofloose coupling, independent of platform etc. SOA will be applied widely as an efficientsolution to Enterprise Application architecture. SOA has not appeared for a long time, andhas not consummated its application, therefore it has been the hot topic at present. It willbe the dominator of software architecture.This paper systematically analyses some problems in the construction of enterpriseapplication system, and points out the restriction of the existing enterprise informationalsystem architecture. For instance, extra professionals and money involved in the existingcomplex and chaotic enterprise systems; The application that is very difficult to integrateor the defective effect,which cannot provide satisfying support for the development ofthe enterprise service and so on.This paper analyses the basis theory and model of SOA, the duty and function ofevery roles in SOA, the related factors of quality of service, and discusses the traits anddevelopment future of SOA.This paper has lucubrates implementation technology of SOA under Internet WebService, mainly including the basis knowledge and protocols and criterions of WebService: XML, SOAP, WSDL and UDDI. Moreover it compares with traditionaldistributed computing technologies, and illustrates the traits of Web Service, such asplatform independently, extendible and integration easily.Following these theories, the paper propose a model for enterprise applicationdevelopment based on SOA combining with classical object-oriented analysis and designmethod (OOAD) and traditional software architecture upon practice. This model includesfour layers: user interface layer, business logic layer, data access layer and data layer. Allthe functions of every layer are divided into different services, and all the services arecomposed to service warehouse managed by private UDDI, and then they are composedto the whole functions and business logic through call and combination.This paper unifies the characteristic of the processed foods profession enterprise information, to propose the improvement architecture of the processed foods professionERP system based on SOA, and has carried on the partial realizations and confirmed theapplication based on the SOA method. As a result of the limit of cost and resources, midand small enterprise is unable to invest the massive funds to carry on the rebuilding of theSOA comprehensively. This paper applies the theory of SOA to the system, which has theinstruction significance to the information of the home mid and small enterprise that canbe further consummated.
