ITPEC FE Subject A April 2025 Question 47
ITPEC FE Subject A April 2025 — Question 47 of 60
UML uses multiple viewpoints with standardized object-modeling notation — each diagram type (use case, activity, sequence, class) shows a different aspect of the system.
Why not others:
- (a) — describes an ER diagram (entities, attributes, relationships) — a data-modeling technique, not UML
- (b) — describes a DFD (data flows, sources/sinks, data stores) — a separate methodology
- (d) — describes a decision table/tree (conditional branches for a single request) — not UML
Key rule: UML = multiple viewpoints + standardized notation for object modeling.
