A Pattern-based Model Transformation Approach to Enhance Design Quality

Recently, the impact of design patterns on software quality has attracted a gradual attention since design patterns encapsulate valuable knowledge to resolve design problems and improve design quality. As an attempt towards the investigation of applying goals and design patterns to realize the model transformation, we proposed, in this paper, a goal-driven model transformation by applying design patterns to transform an analysis model into its corresponding design model with an emphasis on the non-functional requirements. The use of goals makes it easier to transform the functional and non-functional requirements into the software models, and derives the candidate design patterns to help satisfy nonfunctional requirements for resolving the design problems and improving software quality.
