Stepwise refinement is a development methodology in which software components progressively evolve under strict adherence of proven properties. This requires means to check whether a new version of a component – with potentially different interface and behavior implementation – refines the behavior of its predecessor. Where architecture description languages (ADLs) support refinement checking, the...
Due to the increased complexity of software development projects more and more systems are described by models. The sheer size makes it impractical to describe these systems by a single model. Instead many models are developed that provide several complementary views on the system to be developed. This however leads to a need for compositional models. This paper describes a foundational theory of...
A code generator systematically transforms compact models to detailed code. Today, code generation is regarded as an integral part of model-driven development (MDD). Despite its relevance, the development of code generators is an inherently complex task and common methodologies and architectures are lacking. Additionally, reuse and extension of existing code generators only exist on individual parts...
