Research Of Enterprise Application Integration Architecture Based On SOA

Now Many enterprises lack of a comprehensive planning process in the process of informatization construction, which lead to the emergence of a large number of enterprise information and business processes island, making it impossible for enterprises to effectively share information, achieved more collaboration and business process automation. Therefore enterprise application integration (EAI) emerges. The development of dynamic e-commerce brings forward higher requirements for EAI, Enterprises need integrated with the internal or external application systems to support current operations and also need for a more flexible, easy to expand and change integrated system to support the ever-changing business logic. So EAI extended to a wider context.Under such circumstances, the traditional model of EAI will not be able to meet the needs of enterprise application changes because of the complex peer to peer's interface way, especially for those faced with frequent changes in the demand for business process management system, even more so. So more effective and flexible model to meet the dynamic e-business development and integration requirements is necessary. The emergence of SOA fill the vacancy, Loosely coupled with the characteristics of SOA, message-oriented communications and characteristics of the process concerned, which meet the needs of enterprises to rapidly build flexible integrated application.This paper outlines EAI and SOA-related theory, discusses the relationship between SOA and EAI and analyses the current fashion for the products based on SOA, then proposes a framework for enterprise application integration based on SOA focusing on the structure of the relevant technology. Finally, a demonstration project to test the feasibility of application integration framework is put forward.
