Please complete two Data Flow Diagrams (DFD) using Figures 6-21 and 6-22 as examples from picture 1 below. I also attached another example below which is my friend's work from the same course for the same assignment. Maybe that one is going to be even more helpful. My figures obviously have to be different than my friend's although we chose the same retailer to do our project on so please keep that in mind. Read the objective below, look at the examples and get to making the DFD's. Thank you.

One DFD should reflect the before U-Scan it (self-scanning) equipment implementation in the retailer you chose (I chose burlington coat factory) and the second DFD should reflect the after U-Scan it (self-scanning) equipment implementation.
