The Research of QVT Model Transformation Approaches

Model transformation is one of the most important part of MDA,the performance of the quality have a direct influence on the software development work.This paper introduces the theory knowledge of model,computation independent model,platform independent model,platform specific model,model transformation and transformation rules.Then through the research of the relatively popular model transformation approaches,such as direct transformation approaches,the transformation approaches based on the relational algebra and the transformation approaches based on the mappings between the metamodel etc,the paper also analyzes their existing deficiency and puts forward the QVT model transformation approaches.The results of the study show that the approaches of this paper have a great advantage of performance.
