Corresponding to Problem and Exercise 5 on page 214. Refer to the attached Adobe PDF document, NOT the textbooks Figure 7-23 on page 215 (I dont like their figures). My version of the figures is clearer than theirs. The context and level-0 DFD depict a university class registration system. Identify and explain potential violations of rules and guidelines on these diagrams. There are 5 errors, each worth 4%. The problem is worth 20% of the assignment.

Here are some exceptions in the diagram that are NOT errors (if you list them, they will NOT count as an error):

While the Context DFD is always numbered zero (as my diagram is), the text shows Level-0 DFDs with processes numbered as 1.0, 2.0, etc. (i.e., a decimal number with a .0). That my diagram has processes numbered without a X.0 format is NOT an error.

The text shows Gane and Sarson process symbols with a line drawn about 20% from the top, with that section shaded in. That my diagram doesnt is NOT an error (indeed, MS Visio doesnt draw them that way).

The text shows Gane and Sarson data store symbols also with a line drawn about 25% from the left of the symbol, with that section shaded in. That my diagram doesnt is NOT an error (same thing for how Visio draws them).
