Task 3: Association Classes in UML Class Diagrams Consider the following modelling alternatives of three classes "Professor," "Student," and Lecture and the respective associations between them. Let the following be a textual description of some relationships on an instance level, i.e. between concrete professors, concrete lectures and concrete students. Diagram 1 teaches 0.. Professor attends Professor Professor 0.. 1 Diagram 2 teaches 0.. 0.. Professor Professor Professor 1 2 3 Complete Textual Description Professor Jones teaches the Requirements Management" lecture. Student Tom Janeway attends the "Requirements Management" lecture. Student Kate Torres attends the "Requirements Management" lecture. Professor Jones teaches Student Kate Torres and Student Tom Janeway in his Requirements Management" lecture. 4 5 6 Task 3A: Evaluate and Explain the Meaning of the Association Class. For each of the above statements in the textual description, decide which diagram contains the respective statement. Assume that further information is known about the involved instances. Also, answer the following question: Which diagram allows the inference that Tim Janeway and Kate Torres attend the same lecture? Tick your answer in the following templates below and explain your reasoning. Consider the special meaning of association classes in your reasoning, where appropriate. Which diagram depicts the following relationship on the instance level? "Professor Jones teaches the Requirements Management" lecture." o Diagram 1 o Diagram 2 o Both diagrams None of the two diagrams Rationale Which diagram depicts the following relationship on the instance level?
