modelldriven

Modelldriven is a software engineering approach in which models are the primary artifacts in the development lifecycle. It covers model-driven engineering (MDE) and model-driven development (MDD), and relates to model-driven architecture (MDA). Practitioners use high-level models to analyze, validate, generate code, and deploy systems, seeking greater abstraction, consistency, and automation.

Core elements include modeling languages and meta-models (for example UML, SysML, and DSLs), model transformation engines (M2M and M2T), code generators, and model repositories. Transformations map models to other models or to executable artifacts, while some environments support executing models directly as simulations or runtime specifications.

Processes typically begin with domain modeling and requirements, followed by platform-independent modeling and platform-specific refinements. Tooling enables generation of boilerplate code, tests, and documentation, while traceability links models to requirements and artifacts. Validation and verification, including simulation and model checking, help detect issues early.

Benefits include higher abstraction, faster iterations, and consistency across artifacts, while allowing easier adaptation to new platforms. Challenges involve tool fragmentation, learning curves, potential divergence between models and handwritten code, maintenance burden for large models, and performance or integration limits for generated artifacts.

Applications span software-intensive systems, embedded and automotive engineering, aerospace, and business process management. Critics note that model-driven methods are not a universal cure and require mature toolchains and disciplined modeling practices to realize gains.
