a. Figure 1(the DFD depicting the receipt of goods and services) shows an update to the vendor master data from bubble 2.1 and another update to that same data from bubble 2.3.
Discuss the difference(s) between these two updates. Be specific as to the nature of the data being updated in each case.
How would your answer to this question be affected by your assumption about whether the purchase order receiving notification entering bubble 2.1 was "blind" as to quantities? Explain
Figure 2 shows still a third update to the vendor master data from bubble 3.1. Speculate as to the nature of this update. Be specific.
