Data flow diagrams are used by IS auditors to:

A. order data hierarchically.

B. highlight high-level data definitions.

C. graphically summarize data paths and storage.

D. portray step-by-step details of data generation.

Explanation:

Data flow diagrams are used as aids to graph or chart data flow and storage. They trace the data from its origination to destination, highlighting the paths and storage of datA. They do not order data in any hierarchy. The flow of the data will not necessarily match any hierarchy or data generation order.
