Research On EAI Focus On Business Process Integration

Enterprise Application Integration(EAI) is a new technology recently. To link the existed application systems, implement the cooperation among the application software systems , share the information by using the resources of enterprises and avoid the "island" for the enterprise are the destination of the EAI.With the development of the enterprises, the IT innovations bring up a lot of applications that are compositive, distributed and variational .The traditional enterprises have many applications and the manner of point to point among them. The approach is very complex, and the applications are hard to share information and resources. Furthermore, the cooperation among the applications is more frequently. So an application system that can integration the existed and new applications is necessary. Wherefore the integration approach of integration platform becomes a new research problem for discussion.With the deeper development of enterprise and the growing of e-business,The opening and cooperation among enterprises is more and more important. Not only to open inner business processes of enterprise favors the employee to use the information and achieve operation, but also to provide some processes to clients and other enterprises by Web. Here, the EAI realizes the communication and cooperation among the enterprises and bring the more merits to the enterprises.In a large-scale hospital system, the application systems are heterogeneous systems which distributed on different platforms, based on diverse data formats and solutions. When the processes are integrated, the processes' interaction and services shared among them are difficult to complete. The background of this paper is based on hospital ,This paper provides a expandable framework of business processes integration, which implements seamless integration among several systems and makes them share information and seems to be a whole. Through defining transfer interfacemodule and adapter, business processes are improved and systems increase their flexibility, maintainability, which is suitable to the change of business. At the last of this paper, we designed the flow of hospital.
