| This thesis analyzes the development course and general state of EAI, including the general situation and specialty about related technology and products. This dissertation studies the issues on the Model of Enterprise Integration, the critical theory and technology used on EAI, message service, the distributed transaction based on MOM and TP context. In particular, it focuses on the problem of an EAI architecture based Message Bus, etc. The author also gives an example to explain how to design and implement the Enterprise Application Integration Platform and to prove this scheme's validity. The results show the effectiveness of those approaches proposed. The fruits of this dissertation can be used in the research and development of products on EAI. It is very helpful to guide the project on implementation of EAI. The contributions of this dissertation can be summarized as following:1) This paper analyzes layer-based software architecture and summarizes five architecture patterns for EAI. The patterns allow for integration of commercial off-the-shelf applications into a unified enterprise framework facilitating true application portfolio interoperability. The concepts of architecture patterns and design patterns can be used in a structured and disciplined manner to establish a generic framework.2) In this paper, it presents the notion of Messaging Bus based message service. After analyzing the functions of Message Bus and Adaptor, this paper will provide detailed designs of these parts.3) This paper discusses one case about the designing and implementation on a EAI project ( Cross-bank Bankcard's Payment System based on Message Bus ) . The solution integrates standard distributed object transactions and conditional, intelligent asynchronous messages in one single unit-of-work. By this project; the author verifies the feasibility of the systematic framework and realization tactics presented before. This project has been implemented successfully and gained good effect. |
