摘要
文章介绍了遗产软件开发的相关概念,给出了常用的遗产软件开发模型。分析了遗产软件开发中所要解决的主要问题,其中程序理解在开发流程中具有举足轻重的作用。通过一个实例详细解释了如何对程序进行理解,并介绍了在程序理解基础上如何对遗产软件进行重构。
In this paper, concepts on Legacy Software including forward engineering and reverse engineering are introduced and the development models of legacy software in common use are presented. Then the main problems in developing are discussed. This paper also interprets the method to understand programs by one case,which is important during the process. Finally, how to re-construct the software system is described.
