Improved Iterative Object-Oriented Reengineering Process based on Dynamic Coupling Measures

Reengineering from degenerated but in-use legacy systems to high-maintainable object-oriented (OO) software is becoming a hot research area in software engineering. The iterative reengineering process provide a gradually approach to replace the legacy system and satisfy the quality and functionally requirements. Meanwhile, based on the observed relationships between software coupling and external quality factors of OO system, a sophisticated and operable coupling measures framework is stated. This paper proposes an improved iterative reengineer process for achieving a low-coupling and high-maintainable OO system using dynamic software coupling measures. As an enhancement, a formal dynamic coupling evaluation process is discussed detailedly. Moreover, two possible methods are given for conducting software engineers to optimize reengineered system´s external quality.
