The Impact of Design-level Class Decomposition on the Software Maintainability

The quality of the software's internal structure tends to decay due adaptation environmental changes. Therefore, it is beneficial maintain software benefit future phases life cycle. A common correlation exists between decaying structures and problems like smell maintenance costs. Refactoring a process artifacts based on smell. Decomposition classes one most refactoring actions Blob performed at source code level. Moving class decomposition design artifact seems affect maintainability positively. studying impact design-level essential ascertain benefits implementing decomposition. metrics-based evaluation shows that positively impacts with rank biserial value 0.69.
