Abstract

This paper evaluates the suitability of dominance trees as a means of re-modularising legacy systems. It uses two factors to assess the suitability of the dominance tree approach as a restructuring mechanism. Firstly, it considers if dominance tree analysis identifies suitable reuse candidates and secondly, if the candidates generated represent an improvement to the structure of the code. Applications from two domains and software written in two development languages are used to evaluate the dominance tree's suitability factors. Sequential versions of the software are used to identify specific changes that are made to the software over time, to ensure that the reuse candidates identified are supportive of software change. The results show that overall the dominance trees are useful for software re-modularisation. Furthermore, the results of this study have revealed some interesting observations regarding the general characteristics of software and the process of software change.

评估C和COBOL的优势树的使用

本文评估了优势树作为一种重新模块化遗留系统的方法的适用性。它使用两个因素来评估优势树方法作为重组机制的适用性。首先，它考虑优势树分析是否确定了合适的重用候选，其次，生成的候选是否代表了代码结构的改进。使用来自两个领域的应用程序和用两种开发语言编写的软件来评估优势树的适宜性因素。软件的连续版本用于确定随着时间的推移对软件所做的特定更改，以确保确定的重用候选项支持软件更改。结果表明，总体而言，优势树对软件再模块化是有用的。此外，这项研究的结果揭示了一些关于软件的一般特征和软件变更过程的有趣观察。
