Moreover, it will present a formal semantics of the diagram. The lecture will present these different diagrams and their interplay. UML diagrams range from class diagrams that can be used both for conceptual modeling as well as planning the structure of an implementation, over state machines modeling the behaviour, (composite) structure diagrams describing the interaction of components, to interaction diagrams modeling typical interactions of the user with the software system. The Unified Modeling Language (UML) is an international standard graphical notation for software engineering. Introduction to Theoretical Computer Science Written exam will take place on July 26th, 11-13h This review is for the exam written on 26th of July this year only. Held at Friday 21th of October at 1pm in room G29-E20. A join will only send outgoing token(s depending on the number of outgoing flows) once it has received a single token on each incoming flow.Modelling with UML, with Semantics Modelling with UML, with Semantics The review of the exam on 'Modelling with UML, with semantics' will be A fork will fire as many tokens as it has outgoing flows on receipt of an ingoing token. You need to imagine a virtual token traveling along the control flows. The fork following Form submit actually does, what you are asking for.Īctivity diagrams are derived from Petri nets. I guess the other named flows should also rather be guards. The Yes/ No should be written in brackets (like ) to make them guards, which the actually are.The Form not filled and No form on page flows are also pointless without connected actions (which should likely be some error actions).That's pointless and you should just remove the flow. The second has an unguarded, unconditional flow top from a fork to a join.I guess you just miss a path down to bypass Log Tracking The first has a ConditionalNode with no alternatives.Like I have trouble understanding the details of your question. ![]() Basically you are right: you use a fork to create a "forked off" flow.
