Figure TB-4

Question 114

Essay

Figure TB-4.1 is a "generic" level 0 data flow diagram (DFD),taken from Figure 4.5 in the text.
Required:
Using good data flow diagram construction techniques draw a diagram to explode bubble 3.0 to its next lower level.Diagram 3.0 should contain three processes,appropriately numbered,and should contain the following data flows in addition to those in the level 0 diagram (see NOTE):
a.
Flow H runs from the first process to the second.
b.
Flow I runs from the first process to the third.
c.
Flows J and K run from the second process to the third.
NOTE: Assume that the flows shown in the level 0 diagram affect diagram 3.0 as follows:
