基于SOA的遗留系统再工程的研究与应用

Research and Application on Re-engineering of Legacy System based on SOA

遗留系统的再工程是企业信息化建设必须解决的问题,在基于SOA的企业遗留系统复用框架的基础上,给出了通过Web Services技术将遗留系统从数据层、业务层、应用层进行封装的模型,并结合B/S结构的Web应用程序开发现状,实现了SSH框架下的遗留系统再工程过程。

The re-engineering of enterprise legacy system is a problem that must be solved in the phase of enterprise informationization. On the base of a enterprise reuse framework; this paper proposes a model which encapsulate legacy system on data layer, business layer, application layer by Web Services, and combined with the status of the Web application development using B/S structure, realized the re-engineering process of legacy system under SSH framework.
