I am very new to UML and UML activity diagrams. my question is suppose in a student course registration system after student successfully login to the system there are 3 options add course, delete course or review courses then how we can implement this in UML activity diagram.
can I use fork here ? but I know fork is used when there is simultaneous actions. this is not simultaneous action. student can either add course delete course or review course. can anyone help me? any help is appreciated.
