Abstract:
The quality of software systems depends heavily on the quality of their structure, which affects maintainability and readability. To improve the quality of structure, a system can be restructured. This paper describes a restructuring process, which uses a combination of strongly connected component analysis, dominance analysis, and intra-modular similarity clustering to identify and preserve structures that have been thoughtfully placed together, but would be separated by pure metric-based or similarity-based techniques. The use of the proposed method allows a significant reduction of the number of components that should be moved. Therefore, the number of false movements is alleviated. The proposed approach was implemented in a prototype and illustrated by statistics and examples from 18 open source Java projects. A coherence metric is introduced to further improve restructuring results.
