Transformations' Study Between Requirements Models and Business Process Models in MDA Approach

Abstract Models transformation has become in the last decade, the primary key in the Model Driven Architecture (MDA) approach. Most of these models’ transformation are made between one or many abstraction levels (higher level, average level, or lower level). For that, the Object Management Group (OMG) offers for the MDA approach three abstraction levels, which are “Computation Independent Model” (CIM: the higher abstraction level), “Platform Independent Model” (PIM: average abstraction level) and “Platform Specific Model” (PSM: lower abstraction level). Hitherto, most researchers focused on the transformation between average abstraction level and lower abstraction level because those levels have multiple common points. However, the transformation between higher abstraction level and average abstraction level is rarely discussed because they are two distinct levels that can contain higher abstraction model nature, such as Requirements models and Business Process models. Therefore, our contribution in this paper is to study different transformations approaches between Requirements and Business Process models in the higher and average MDA abstraction levels. To do so, we study the selected approaches, analyze the results descriptively, then discuss them, plus propose new taxonomies based on the deduced evaluation criteria.
