Textbook Problem

Use the DFDs in Figures 13.3 (pg. 502), 13.4 (pg. 502), and 13.6 (pg. 504) to solve this problem.

Prepare a four-column table that summarizes the AP/CD processes, inputs, and outputs. In the first column, list the two processes shown in the level 0 diagram (Figure 13.3). In the second column, list the subsidiary functions shown in the four lower-level diagrams (Figures 13.4 and 13.6). For each subsidiary process listed in column 2, list the data flow names or the data stores that are inputs to that process (column 3) or outputs of that process (column 4). (See Note.) The following table has been started for you to indicate the format for your solution.

Note: To simplify the solution, do not show any reject stubs in column 4.
