Compare and contrast the use case diagram and an activity diagram
What will be an ideal response?
A use case diagram is a visual meta-model: it does not model the use case itself, but the associations between actors, use cases, and the system. It also depicts "extend" and "include" relationships between use cases and provides us with a visual table of contents. An activity diagram is a general-purpose diagram for visualizing and verifying a logical flow. For a use case with a complicated alternate flow, an activity diagram is a very helpful tool. Its simplicity facilitates communication between development stakeholders.
