Prepare a four-column table that summarizes the purchasing processes, inputs, and outputs. In the first column, list the three processes shown in the level 0 diagram (Figure). In the second column, list the subsidiary functions shown in the three lower-level diagrams (Figures). 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). The following table has been started for you to indicate the format for your solution.
