| Question 296 |
A black hole in a DFD is a :
| A data store with no inbound flows | |
| A data store with only in bound flows | |
| A data store with more than one in bound flow | |
| None of these. |
Question 296 Explanation:
Black Hole: A processing step may have input flows but no output flows.
Miracle: A processing step may have output flows but now input flows.
Grey Hole: A processing step may have outputs that are greater than the sum of its inputs – e.g., its inputs could not produce the output shown.
