Research On The SOA-based ERP System Application

With the development of information technology, ERP management system has become the right-hand man of business management for its outstanding management thinking and advanced technology means, and save a lot of human and material resources for businesses. But there are many problems in the existing ERP system, such as different corporate or departmental information systems are isolated, can not effectively achieve information sharing; the enterprise’s existing ERP system is not flexible to adapt to changing business needs, it needs to change the system or do secondary development when business processes changed.In order to improve the problems of system rigid, information isolated, and not flexible enough in ERP system, we build a SOA-based dynamically reconfigurable ERP system. SOA put serve as the core element, and have loosely coupling characteristics between services. We just need to re-register new services to meet the changes of the enterprise business processes. To facilitate data transmission and sharing, the entire ERP system adopts B/S mode.Firstly, this paper researches the concept of ERP, current research status and the development process of ERP. Summarizes the characteristics of ERP and dynamic ERP, analyze the existing problems in the ERP. Secondly, research on the SOA architecture system for the problems in the ERP, analysis of the characteristics of SOA, and according to the above analysis, architecture a SOA-based dynamic ERP system structure, and elaborated on the specific technology in the architecture. Using some excellent designs patterns in the design, such as factory model, proxy pattern and singleton pattern. Then, research the dynamic combination of the service release layer in the five-story architecture, on the basis of summing up the results of previous, to improve the efficiency of the dynamic combination, proposed a dynamic combinatorial algorithm based on semantics. Finally, Apply the architecture and algorithm proposed in this article to Jilin Xinghua feed factory ERP system and verified.The result of the ERP system running time and performance can be shown that the algorithm and architecture proposed in this article can meet the dynamic needs of the enterprise, and has better scalability and maintainability.
