BAS: A Case Study for Modeling and Verification in Trustable Model Driven Development

Multi-view modeling and separation of concerns are widely used to decrease the design complexity of the large-scale software system. To ensure the correctness and consistency of multi-view requirement models, the formal verification technology should be applied to the model-driven development process. However, there still lacks unified theory foundation and tool supports for the rigorous modeling approach. To solve these problems, we implemented an integrated modeling and verification environment tMDA (Trustable MDA) based on the theory of UTP. In tMDA, developers model system requirements with UML static and dynamic models and verify the correctness and consistency of different models. A multidimensional model is proposed, which supports the consistency verification, liveness and safety property verification, OCL constraints and LTL formula verification. A Bank ATM System (BAS) is introduced to demonstrate how to utilize tMDA for design and verification.
