A Review of Detection of Model Smells in UML Model

An increasing trend of MDE and need of high quality software has made the quality of model of great importance to the software development industry. Model smells i.e. bad smells in models are the structures in models that indicate the poor quality of design and an opportunity of improvement. Model Smells are the results of poor design decisions and make the design fragile, difficult and costly to maintain, evolve and reuse. To develop high quality software in MDE paradigm, detection of model smells is a crucial activity for developers. This paper explains the model smells, approaches and tools available for their detection.
