Research and Implementation of Design Pattern-Oriented Model Transformation

Abstract

Design pattern describes a repeatedly presenting issue during software designing, as well the solution to it. Applying design pattern enables developers to reuse it to solve a specified designing issue. Applying and maintaining design pattern in models is a duplicating work. In order to automatically apply design patterns in models, we propose a design pattern oriented model transformation approach. In this paper, we designed a set of atom mappings and pattern mappings, as well the combination of them, the model transformation code template. Such a template can generate XSLT based model transformation code, and enable automatically applying design pattern in software models. A case study is provided to demonstrate our approach.
