A Proposed Engine Implementation Mechanism to Execute the Code of Relations Query/View/Transformation Language

Depending on the authors' best knowledge and despite of the well documentation of the transformation language Query/View/Transformation QVT-Relation which is used as a tool in Model Driven Architecture (MDA) technique that provided by Object Management Group (OMG), there is still no specific description about the execution engine for the QVT-Relations (QVT-R) Transformation Language because the aim of MDA technique is to separate the system implementation from the system description. For the most of the computing industry, and a major standardize by the OMG, Model Driven Architecture becomes the preferred method to re-use program code. "MDA separates the fundamental logic behind a specification from the specifics of the particular middleware that implements it".
