| Question 4 |
A DFD that can be used to plan or record the specific makeup of a system is called:
| Level 0 DFD | |
| Level 1 DFD | |
| Level 2 DFD | |
| Level 3 DFD |
Question 4 Explanation:
→ A level 2 data flow diagram (DFD) offers a more detailed look at the processes that make up an information system than a level 1 DFD does It.
→ Higher level DFDs can be transformed into more specific lower level DFDs with deeper level of understanding unless the desired level of specification is achieved.
→ Higher level DFDs can be transformed into more specific lower level DFDs with deeper level of understanding unless the desired level of specification is achieved.
