UML Activity Diagram — represents workflows with sequential steps and conditional branching
An Activity diagram models the flow of activities in a process, including sequential execution, decision points (branching based on conditions), and parallel paths. It is essentially UML's version of a flowchart, making it ideal for business process modeling.
- •Correct answer: a) Activity diagram — directly represents workflows, execution sequences, and conditional branching using decision nodes, fork/join bars, and activity flows.
Why not the others:
- b) Class diagram — shows the static structure of classes, their attributes, methods, and relationships (inheritance, association). No workflow representation.
- c) Component diagram — depicts the organization and dependencies among software components. Focuses on system architecture, not process flow.
- d) Object diagram — a snapshot of object instances and their relationships at a specific point in time. Static, not behavioral.
Key rule: When a question mentions workflow, sequence of steps, or branching/conditions in UML context, the answer is Activity diagram.
