Figure TB-4.1 is a "generic" level 0 data flow diagram (DFD), taken from Figure 4.5 in the text. Reguired 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) Flow H runs from the first process to the second. a. 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 O diagram affecet diagram 3.0 as follows: 1. Flow D runs to the first process in diagram 3.0. 2. Flow B runs from the third process in diagram 3.0. 3. The data flow running from the data store runs to the second process in diagram 3.0 2.0 Source Data Store 1.0 3.0 8 Figure TB-4.1 Generic level O flow diagram LEM 2 3-4.5 shows a level 0 logical data flow diagram for a billing system.
