Quizplus · Accepted Answer

When data flows between two symbols on a DFD and have more than one data item, more than one arrow is needed if the data elements flow at different times. This is because multiple arrows indicate the sequential order of the data flow. If the data elements always flow together, a single arrow can be used. If the data elements flow to different locations, multiple arrows with different destinations should be used. There is no guideline for the use of single or multiple arrows, so it is up to the analyst to determine the most appropriate method based on the specific context of the DFD.
