Modellvezérelt

Modellvezérelt, also known as model-driven development (MDD), is a software development paradigm that focuses on creating and manipulating models as the primary artifacts. Instead of directly writing code in a traditional programming language, developers work with higher-level models that represent different aspects of the software system. These models can describe the system's structure, behavior, data, and user interface.

The core idea behind modellvezérelt development is to automate the generation of executable code from these models. This is typically achieved through specialized tools called model transformations or code generators. These tools translate the abstract model into concrete code in a target programming language, such as Java, C++, or C#. This automation aims to reduce manual coding effort, improve consistency, and facilitate faster development cycles.

Modellvezérelt development often involves using domain-specific languages (DSLs) or general-purpose modeling languages like the Unified Modeling Language (UML). By abstracting away low-level implementation details, developers can concentrate on the system's business logic and architecture. This approach can lead to improved maintainability and reusability of software components, as changes can often be made at the model level and then propagated to the generated code.

Key benefits of modellvezérelt development include increased productivity, enhanced quality through reduced errors, and better communication among stakeholders due to the visual nature of models. However, it also requires investment in modeling tools and a shift in the development team's skillset.
