Verifiable architectural interface for supporting model-driven development with adequate abstraction level

It is not easy to design software architecture reflecting the intention of developers and implement the result of design as a program while preserving the architectural correctness and adequate abstraction level. Archface, an architectural interface mechanism, plays a role as an ADL at the design phase and as a programming interface at the implementation phase. Design and code can co-evolve with Archface at the center of the development process. This paper proposes a verifiable architectural interface that can check the traceability between design and code. For this checking, we use an SMT (Satisfiability Modulo Theories) solver, a tool for deciding the satisfiability of logical formulas. Adopting our approach, we can construct MDD tools supporting adequate abstraction level when they generate code, recover a design model from code, and check the traceability between a design model and its code.
