Towards Correct Modelling and Model Transformation in DPF
MetadataVis full innførsel
Model-driven engineering (MDE) is a model-centric software development methodology. It promotes models as first-class entities in software de- velopment. Models are used to represent software along software devel- opment process and to finally generate software automatically by model transformations. Thus, the quality of software is highly dependent on models and model transformations. This thesis devotes to construct cor- rect models and model transformations in Diagram Predicate Framework (DPF), which provides a formal diagrammatic approach to (meta)modelling and model transformation based on category theory. The thesis presents the DPF Model Editor, a graphical (meta)modelling editor for DPF which supports diagrammatic (meta)modelling. In addi- tion, we propose bounded verification approaches of models and model transformations respectively by using Alloy. Alloy consists of a model- ling language and the Alloy Analyzer to examine Alloy specifications. The verification approaches proposed in the thesis translate models and model transformations into Alloy specifications, which are passed to the Alloy Analyzer to verify whether the models and model transformations satisfy some desired properties. Because of the inherent limitation of Alloy, the verification approaches also encounter a scalability problem: it may take quite long time or be- come intractable to verify larger models or complex model transforma- tions. To tackle the problem, the thesis also presents several techniques to optimize the approaches. The first technique splits models into submod- els and reduces the verification of the models into the verification of some submodels. The other two techniques are proposed for the verification of model transformations: one technique uses a modelling approach to sim- plify model transformations; while the other one optimizes the translation of model transformation rules. Experim at these tech-niques alleviate the scalability problem.
