Enterprise Application Integration And Enterprise Portal Research

Enterprises scheme out business process according to their business requirements and develop the relevant information systems to assistant their extension. With the development of Information Technology, the problem about "the Island of Information" becomes more and more serious. Thus the concept of Enterprise Application Integration (EAI) came into being, which can, connect the various related isomerous information systems, applications and data sources in accordance with the requirements of business processes by using various technical means, thereby to make E-Commerce, ERP, CRM, SCM and OA, databases and other important systems share seamlessly and operate uniformly, and finally to realize the goal of business process integration.The different users of systems (customers, business partners, staff, etc.) can be provided unified and personalized interface by Enterprise Portal (EP) systems, which allowing customers, employees, partners or suppliers to link business processes directly, serving themselves without deeply understanding. Thus, it is not only saving tremendous resources for the enterprise but also extending the business market to the Internet.This paper demonstrates the research background, object and method, as the starting point and the basis for the whole paper. Focusing on the concept and the structure of EP technology, the logic structure and physical structure about the EAI are analyzed. In addition, IBM MQSeries products are taken as the examples to highlight the middleware technology which is used most commonly in the EAI. Subsequently, the integration project of Tianjin Cosco freight Co., Ltd is taken as the case. Finally, in the conclusion, the issues of the project are summarized, and the development of the EAI and EP in the future is prospected.
