摘要：The main concerns of Enterprise Application Integration (EAI) are making applications work together and reducing their complexity. Service Oriented Architecture (SOA) has been presented as an architectural design style and principles which can better align IT initiatives with business requirements. An SOA based Enterprise Application Integration approach is proposed in this paper. Using SOA methods and design styles, we model the business process of the enterprise and identify process blocks that can be group as services. The existing legacy applications are analyzed to look for functionalities that can be mapped to the identified services. In situations where a service in the business process cannot be mapped to any existing legacy implementation or composed from existing services, the service has to be developed as a new service which is loosely couple, re-useable, extensible as well as interoperable and maintainable. It is verified that this approach ease the composition of existing services and orchestration new business processes. ? 2010 IEEE.
