Research And Implementation Of Purchasing Management For Small And Medium Sized Manufactories System Based On SOA

In recent years, with the advance of the enterprise information construction, the needs of large enterprises have saturated, but the enterprise information construction needs of small and medium-sized enterprises has increased dramatically due to their characteristics. More and more small and medium-sized enterprises join into the enterprise information construction. The growing business requirements make the inter-department application appear more frequent. The existing system architecture cannot meet the demands of business collaboration. In the face of all these problems, service oriented architecture technology arises at the historic moment.Under the network environment, SOA is a software architecture of business integration. It has a broad application for the characteristics of good coupling, service reusability and platform-independent. The core essence of SOA is the service. It puts all the things as services and completes the business requirements by calling services. It realizes the reuse, assembly and integration of the original system. When necessary, these services can assemble the demand application by themselves-namely connected service providers and users set. They combine together to achieve specific business, so the business able to adapt the changing requirements.This paper brings forward the designing ideas of purchasing management system based on Services Oriented Architecture, which is an important part of supply chain systems. This thesis aimed to build a purchasing management system which is based on service oriented architecture, Web Services technology and.NET platform. It has some properties such as coarse granularity, low coupling, and reusability.This paper based on SOA technology studies how to apply the SOA to the actual project. Firstly the paper discusses the definition and characteristics of SOA and web services for the support of SOA, and studies SOA technology platform. Secondly this paper analyzes the needs of enterprises in Tengda project and the needs of the enterprises purchasing management, business process and business function in detail. Thirdly we design the purchasing management system architecture for Tengda project combined with the SOA idea and Web Services technology based on the.NET platform, and then we present the key technology for the core business-order processing.
