Research On The Financial Management System For ERP Instructional Simulation Environment Based On SOA

With the rapid development of enterprise informatization, ERP systems have been used more widely in enterprises. Then the situation of lack ERP application talents was appeared. To satisfy the enterprises demands, ERP teaching was born in universities. In the ERP instruction process, ERP teaching simulation plays an important role. As a core of ERP simulation system, the financial management system plays a vital role in ERP teaching. The existing financial system of the ERP instruction simulation has functional problems, such as lacks of financial budget and cost management function. In the software architecture, most teaching simulation software system's structure lacks flexible design, and causes the system inflexibility. SOA architecture is based on the service, which can enhance the system flexibility through flexible calls the services, and provides theoretical basis and implementation in order to solve the flexibility of the system. Therefore, according to the ideological of SOA to construct financial management system in ERP instructional simulation environment has important significance in theory and practice.Firstly, the dissertation has systematical study ERP simulation teaching, financial management system, and application status of SOA. On the basis, financial management system of ERP teaching simulation is analyzed and the system functions are determined. It makes the function of the system more comprehensive. SOMA-based service-oriented analysis and design ideas and Powerdesigner 12.5 modeling tools are used to construct the system business process models, which makes the system business process more flexible.With the analysis of the financial management system requirements, combining the thought of SOA, the dissertation designs the financial management system level and general framework based on SOA. Meanwhile, the system functions are encapsulated as the form of services. Through the services organic called, the system flexible become better and the system problem of rigidity was solved. And then it detailed designs the database. Finally, using Web Service + ASP.NET technology and the service invocation and composition, this dissertation realizes financial management system, and conducted empirical studies combining the Northeast University of Petroleum.
