2. Realization levels of transformations in the framework of MDA in some advanced solutions Solutions that are focused on CIM -> PIM transformation [6, 7, 8] can’t insure that a PIM contains all the necessary information, and that the presentation of the PIM is formal enough to be able to transform it into the correct PSM [4].
