MDA, or Model Driven Architecture, is a software design approach that focuses on creating models to represent the structure and behavior of a system. It emphasizes the use of high-level abstractions to define system components, which can then be transformed into executable code. This method helps streamline the development process and improves communication among stakeholders by providing a clear visual representation of the system. The MDA framework is based on the Object Management Group (OMG) standards, which promote the use of Unified Modeling Language (UML) for modeling. By separating the specification of system functionality from its implementation, MDA allows for greater flexibility and adaptability in software development, making it easier to update or modify systems as requirements change.
