The Research And Implementation Of Purchase And Supply Management System Based On SOA

With the development of rear service socialization and information technology,digitallogistics has become the important component of information construction for college.Asthe core part of logistics management for college,logistic purchase and supply managementfaced with lots of problems,such as low efficiency,low data sharing, and complex businessprocesses.The establishment of digital logistic purchase and supply management system forcollege is one of the most pressing tasks of logistics management for college.Logistic purchase and supply management system for college,which is taken forpooling the scattered departments and the data together to form an organic whole,canrebuild business process quickly and easily with the change of business.In view of presentsituation and problems，this paper puts forward design thinking of the college’s purchase andsupply management system based on SOA.SOA is the kind of business-driven softwaredesign pattern as a new generation of software architecture, inaugurating a newservice-oriented era in IT business. With the feature of loose coupling and platformindependency, SOA has a great natural advantage in the field of system integration throughwhich we can break the information island and do the combinations, sharing of informationresources. Moreover, SOA has a better way in the service continuous innovation andimprovement. Now the research on the SOA has been an important subject in the ITbusiness.In this paper,research results are mainly embodied in the following areas:(1)It analyses the research status of the logistic purchase and supply management andsummarizes the deficiencies of the current management,which confirms the implementationof logistic purchase and supply management informationization is necessary.(2)It studies the concept and specific implementation technologies of SOA,theserelated implementation technologies include Web Services and Enterprise Service Bus,anddetailedly analysis the protocol stack of Web Services.(3)It designs the structure of logistic purchase and supply system for college based onSOA,and analysis and illustrates the function structure of system on basis of analyzing therequirement and business process of system.(4)It designs system services from requirement,and distributes service interfaces tosystem users.(5)With J2EE platform and open source products,it achieves the implementation ,deployment and call of Web service,and develops the application by service call.(6)Faced with lots of data which generated by system,it establishs the GM (1,1) modelbased on gray theory,and uses the model to forecasting the profit trend of cafeteriacenter.
