QVT (Query/View/Transformation)

QVT, or Query/View/Transformation, is a standard used in model-driven engineering to manipulate data and models. It defines ways to query information, create views of data, and transform data from one model to another. Essentially, QVT allows developers to extract specific information from complex data structures, present it in a more understandable format, and change it to fit new needs or systems. This is particularly useful in software development, enabling better integration and reuse of models across different applications and frameworks.
