SOA-based Purchase And Inventory Management System Design And Implementation

Web Services is the core technology of SOA, solved many problems of traditionaltechnologies, different systems can share data, thereby achieved a high degree of resourceintegration. ESB is the middleware technology of SOA, message and service can be sharedand interactive in the heterogeneous environment, achieved a high degree of integration withother systems, improve efficiency of work greatly.With the development of society and information industry, manufacturing capacity ofcompany continues increase, annual production growth rapidly, the pressure of materialprocurement and distribution of material increases also, while the requirement are more andmore higher to the control of procurement process、the control of warehouse and informationsystems. To solve above problems, the article researched and realized ERP procurement andinventory management system based on SOA. The main works are as follows:1.In this paper, the structure and framework of SOA were analyzed, studied the relevanttechnology of SOA architecture, that is Web Services, ESB, J2EE and database technology,analyze the relationship between procurement and inventory management system based SOAwith other modules of ERP, explained the concept and function of ERP procurement andinventory management.2. The article analyzed the need of system, designed the function module of ERPprocurement and inventory management system based on SOA, meanwhile specific functionalmodules were divided of granularity according to detailed business division, draw flow chartsand use case diagram of system.3. The article designed the database, from E-R diagram, data logic structure, to design ofview, the design of the store procedure, finally achieved database system.4.Through analysis and design above, with the development environment of J2EE andthe backstage database of ORACLE, by using of the technology of JavaScript, Java, CSS+ DIV, XML, AJAX, jQuery completed ERP procurement and inventory management systembased on SOA. The system can easily add and remove services according to the actual need ofthe company, provides an interface to other application systems, enterprise-level integratedeasily.5. By testing in various conditions, the SOA-based purchase and inventory managementsystem has achieving the expected results, whose system error prompt is friendly and userpasswords are highly safe. Meanwhile, its system function is relatively complete andperformance is reliable.
