Correlation between Object-Oriented Metrics and Refactoring

Repeated code modification lowers code quality and impacts object-oriented system design. Object-oriented metrics have proven as indicators of problems in system design. They have been grouped in minimal sets, known as quality models, to assess object-oriented system quality. Improvement can be gained by establishing relationships between quality characteristics and metrics computed from object-oriented diagrams. Quality models include metrics that can produce better code in object-oriented systems. Code quality can also be gained with refactoring. Refactoring is used to reduce complexity and eliminate redundant code. It is important to identify when and where to use refactoring. There are many different approaches. This work presents early stage analysis and focuses on exploring whether object-oriented metrics can be used as indicators where in the code refactoring can be used. Through multiple itera tions of successive measurement and refactoring, relation between metric values and need of refactoring can be concluded.
