摘　　要：随着技术的快速发展和需求的不断变更,遗留系统越来越不能满足使用和维护的要求,需要进行再工程.因此,本文描述了一种基于MVC(Model-View-Controller,模型-视图-控制器)的分层增量式再工程,将遗留系统划分为运行环境、核心系统、主要子系统和次要子系统四层,首先将核心系统基于MVC模式进行逆向分析、重构并部署,然后将其它子系统并行再造,逐个部署到新的核心系统上.该方法在一个遗留系统再造过程中的成功应用证明了它的实用性和有效性.With the rapid development of new technologies and appearing of new requirements ,many legacy systems can not satisfy the changed environment and become very difficult to maintain. For these systems,it is necessary to reengineer them to meet the new conditions. This paper presents a MVC-based layered incremental reengineering approach,which divides the legacy system into four layers：running environment,core sub-systems,main sub-systems and minor sub-systems. Core sub-systems are reengineered and deployed first and then others based on MVC pattern. By the successful reengineering process of a legacy system,the model is proved to be practicable and effective.
