软件再工程助手

随着越来越多成功的软件系统成为遗留系统,软件再工程已日益显现其重要性。但对原系统理解的难度影响了软件工程师对原系统进行再工程的效率,特别是从源代码获取设计规约。在软件维护和软件再工程中大量的工作是围绕着源代码的变换,这种变换将程序代码文本或规约文本从一种形式转变成另一种形式,从而使其具有更好的可读性和可理解性。论文介绍了作者与英国DeMontfort大学的研究人员开发的一个非常方便的用于从程序抽取规约(也就是从源代码文本到规约文本的变换)的再工程助手(RA)工具,并使用RA进行一个实例研究。

Software Reengineering Assistant

The importance of software reengineering increases as more and more successful software systems become legacy systems.However,the difficulty of comprehension of the original system hinders software engineers from efficient reengineering of legacy systems ,especially,achieve the designing specification from source code.Much of the work in software maintaining and software reengineering has concentrated on source transformation,which changes the program source code text or specification source text from one form to another form so that these source text can become more readable and understandable.This paper introduces a convenient reengineering assistant (RA)tool which was developed by the author and other researchers in De Montfort University,UK,and can be used to abstract a specification from a pro-gram(i.e.from source code text to specification source text),and give a case study with RA.
