Question 107
|
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 107 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.
