软件再生工程理论及其新的实现方法

Software reengineering theory and novel approach for its implementation

在软件再生工程中为了有效利用遗产系统提供现实可行途径 ,对原系统理解是关键。在利用传统途径理解系统无效的前提下 ,需探讨新的系统理解方法。在对一个典型遗产系统 (电子成型机现场数据采集及管理系统 )进行再生过程中 ,尝试了一些非传统的系统理解方法 ,如使用跨平台的反汇编反编译工具 ,监听分析目标系统运行特征等。本文论证这些方法的有效性 ;

Reengineering offers a practical and feasible approach to use legacy system. Understanding the old system is of vital importance for its implementation. On condition that traditional method is invalid, new method is in need of. We try to use various kinds of non traditional method in the reengineering process of a typical legacy system, for example: using across platform reverse compiling and reverse assembling tools, monitoring and analysing operational characteristics of the objective system. This paper demonstrates their effectiveness and feasibility. It may provide a novel attacking approach for software reengineering.
