Relationships between UML Sequence Diagrams and the Topological Functioning Model for Backward Transformation

The software system needs to be analyzed and designed before the program code is written. A Computation Independent Model (CIM) and a Platform Independent Model/ Platform Specific Model (PIM/PSM) from Model-Driven Architecture (MDA) will be partially considered in this paper. A Topological Functioning Model (TFM) will be considered as a formal CIM, and UML sequence diagrams - as a behavioral PIM/PSM of the software system. The paper presents a short overview of the TFM and sequence diagrams with their constructs, as well as the example of transformation from the sequence diagrams to the TFM.
