This webinar demonstrates the practical realization of standards-based executable modeling in UML, showing its importance for moving forward in a number of, perhaps, unexpected areas, including agile development methods, multi-core programming and model-based system engineering. Today’s Executable UML is based on the OMG’s Foundational UML (fUML) standard, for executable object-oriented and activity modeling, and the Action Language for fUML (Alf) standard, which defines a corresponding textual representation. But this is only the beginning. Additional Executable UML standards are being built on this foundation, including recent ones for composite structure and state machines.
