Automatic Pattern Proposition in Transformation Life Cycle

Transformation patterns optimize transformations and improve their internal structure. This paper presents an automatic method for pattern proposition in transformation life cycles. Our approach combines the transformation engineering by the idea of transformation patterns and proposes appropriate patterns in the design and implementation phases of transformation life cycle. We evaluate the impact of proposed patterns on generated transformations based on several metrics, automatically. The proposed patterns in the design phase are based on the structure of transformation, and implementation patterns are proposed according to the result of the evaluation. Our method is presented as a semi-automatic process for using the transformation patterns in transformation life cycles. The results of applying suggested patterns include decreasing the complexity, memory usage, execution time, as well as increasing the quality, efficiency, and modularity.
