Software Engineering basics - Model-Driven Development (MDD)

Model-Driven Development is an approach where abstract models are the primary artifacts of the development process, and executable code is generated from these models. The emphasis is on raising the level of abstraction.

Models represent system structure, behavior, and constraints using standardized notations such as UML or domain-specific languages. These models are platform-independent and capture business logic more clearly than raw code.

Automated transformations convert models into platform-specific implementations. This improves consistency, reduces manual coding errors, and accelerates development, especially in large systems.

MDD enhances design conformity and traceability, ensuring that implementation aligns with architectural intent. Changes made at the model level propagate systematically across the system.

While MDD requires upfront investment in tools and skills, it is particularly beneficial for complex, long-lived, or safety-critical systems.
