An Analytical Study of Code Smells

Software development process involves developing, building and enhancing high-quality software for specific tasks as a consequence generates considerable amount of data. This data can be managed in systematic manner creating knowledge repositories that used to competitive advantage. Lesson's learned part the also bank advantage subsequent projects by developers practitioners. Code smells are group symptoms which reveal code is not good enough requires some actions have cleansed code. metrics help detect while refactoring methods removing them. Furthermore, various tools applicable detecting smells. A smell repository organizes all available literature about related concepts. An analytical study presented this paper extracts useful, actionable indicative knowledge.
