Answer / guest
Answer: C
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.
