Research On Soa-Based Cloud Computing Enterprise Resource Planning Model

With the innovative development of enterprise management ideas and information technology, ERP (Enterprise Resource Planning) system generates. ERP system is helpful to assist enterprise operations, management and decision-making processes. It can help enterprises save a lot of operating costs. However, the existing ERP system has many shortcomings, such as information systems of different departments don’t effectively share information called "islands of information".When the business processes change, you need to change the system or re-develop the system to adapt well to changing business processes.This master dissertation builds a cloud computing ERP model based on SOA (Services-oriented Architecture) to improve existing ERP system. SOA takes services as the core elements with loose coupling between services and services. When the business processes change, you only need to re-register, publish, call the new services to meet the changing business processes. Deploying ERP systems on the cloud, the enterprises can acquire not only super computing capabilities, but also need not to purchase hardware, network equipment to save a lot of IT costs.Firstly, the master dissertation overviews the concept of ERP, research status, development review, the characteristics of ERP and analyses the current problems of ERP systems. Secondly, the master dissertation introduces the architecture of SOA and cloud computing, analyses the key implementation technologies and characteristics. Based on the above research, this master dissertation builds a SOA-based cloud computing ERP model. The main idea is deploying ERP systems based on SOA on the cloud to solve the problems in existing ERP systems. Besides, this master dissertation builds security architecture to the model. Finally, the master dissertation implementation some parts of the model.
