The first important step in Model Driven Architecture software development is qualitative analysis and specification of structure and behavior of business and its supporting information system as well as software requirements. We continue the research on achieving a qualitative software requirements model, Use Case Model (UCM), based on a formal business model, Topological Functioning Model (TFM), by using formal model transformations. This paper discusses the results of implementation of the transformation from TFM to UCM by using Query/View/Transformation Relations supported by mediniQvt.
