Activity diagrams and use case diagrams.
What is an example of an interaction diagram in UML?
Sequence diagrams.
What is the purpose of the component diagram?
To verify that a system’s required functionality is acceptable and to show the structure of the system.
What does an activity diagram represent?
A series of actions or flow of control in a system, showing both sequential and concurrent activities.
What does a use case diagram represent?
The interaction between a user and the system, showing the relationship between the user and different use cases.
