一个面向服务的应用案例研究

A Case Study of SOA Application

本文从一个现有的信息系统出发,通过分析因为业务增长和环境变化而带来的问题,提出需要进行面向服务的改造。根据面向服务系统的基本原则,从请求之间的状态、请求方式、接口的多样性和体系结构等方面阐述了该系统的改造。本文所描述的SOA改造的方法和体系结构设计以及面向服务改造后带来的优点具有普遍的意义。

Starting from an existent information system and analyzing problems that the system are confronted due to the growing business and the changing environments, this paper points out that information system should be reconstructed from the perspective of the service-oriented architecture. According to the basic rules of constructing SOA system, the paper describes the reconstructions of a representative case of information system from the aspects of the request states, the diversities of request means and interfaces, and software architectures. The methods of SOA reconstruction and software architecture design proposed in this paper and the advantages brought by SOA reconstructions have universal significance.
