Figure TB-4.3 shows a context diagram of a cash sales system.The diagram intentionally violates several of the guidelines and other techniques presented in the text for drawing data flow diagrams.
Required:
Identify as many of the errors in data flow diagram construction as you can.In the diagram,place consecutive numbers (each in a circle)next to the points at which the errors exist.On your solution sheet,list the numbers and write a one- to two-sentence description of each error and what the correct procedure should be.Error 1 is provided as an example of how to construct the solution (but you must place the circled number 1 on your solution diagram).
