Model-Driven Software Refactoring

Abstract

In this chapter, we explore the emerging research domain of model-driven software refactoring. Program refactoring is a proven technique that aims at improving the quality of source code. Applying refactoring in a model-driven software engineering context raises many new challenges such as how to define, detect and improve model quality, how to preserve model behavior, and so on. Based on a concrete case study with a state-ofthe- art model-driven software development tool, AndroMDA, we explore some of these challenges in more detail. We propose to resolve some of the encountered problems by relying on wellunderstood techniques of meta-modeling, model transformation and graph transformation.
