Software is the raw material of the digital age. Only those who master the handling of this raw material will be able to develop marketable systems in the future. Topics such as IoT and Industry 4.0 are accelerating this trend. Model-Driven Software Engineering (MDSE) provides a crucial contribution to successfully addressing this challenge. The book describes the effective use of MDSE from requirements to architecture, design, code generation, and testing. For each phase, paradigms, methods, techniques, and tools are described, with a focus on practical application. The reader learns how a model-based approach can be beneficially applied in practice for the development of an embedded system. The approach is presented independently of modeling tools and in such a way that the reader can easily implement it in their environment.
