ITPEC IP April 2026 — Question 94 of 100

The diagram with processes, labeled data flows, and a data store — option (b) is a Data Flow Diagram.

A DFD models how data enters processes, is transformed, moves between processes or external entities, and is read from or written to data stores. It emphasizes data movement rather than control sequence.

Answer (b)

Why not others: (a) is a state-transition diagram; (c) is an entity-relationship diagram; (d) is a flowchart with a decision branch.

Key rule: Circles/processes, arrows named as data, external entities, and parallel-line data stores identify a DFD.
