逆向工程和再工程在软件预防性维护中的应用

Reverse Engineering and Re-engineering Technologies in Preventive Maintenance

过去在进行软件开发的时候,没有采用科学合理的方法,尤其没有重视原始文档的保存与整理,从而导致了软件危机的产生。为了更好地维护现行软件,有必要理解其内部的逻辑结构,进而根据新的要求,做出相应的维护。这就是软件维护的逆向工程和再工程,本文对此进行了讨论。

In the past time, we developed software without adopting scientific and reasonable methods,and paid no attention to the original documents, and it led to software crisis.To maintain the active software more easily,it is necessary to master the inside logical structure,and we can maintain according to the new requirements. This is called reverse engineering and re-engineering, this paper discusses it in some details.
