This is my first ever DFD that I made after my fair share of learning but I have no way of verifying whether it is correct or not. Although I have taken utmost care to make sure it is right, I may be wrong.
Here is the scenario:
Bebop Records is a mail-order company that distributes CDs and tapes at discount prices to record club members. When an order processing clerk receives an order form, he or she verifies that the sender is a club member by checking the Member file. If the sender is not a member, the clerk returns the order along with a membership application form. If the customer is a member, the clerk verifies the order item data by checking the Item file. Then the clerk enters the order data and saves it to the Daily Order file. The clerk also prints an invoice and shipping list for each order, which are forwarded to Order Fulfillment.
and here is my diagram

Offtopic? Well, aren't you testing my diagram after all?

How this very specific question is going to help other testers apart from practicing DFD? How would you generalize your question to make it more useful for other testers? – dzieciou Aug 28 '12 at 19:16
I have no answer but there is no stack exchange site for software designing. SQA is the closest to the software development process so I posted here. – Dummy Derp Aug 28 '12 at 19:18
Quick search on programmers stack exchange found some eg programmers.stackexchange.com/questions/89454/…. What are you hoping for an answer ? – Phil Kirkham Aug 28 '12 at 20:24
OK, then I will see what I can find there :) – Dummy Derp Aug 29 '12 at 1:50
Since you've already made a new post on ProgrammersSE, I'll simply close this. (Typically I would have just moved it to over there.) – corsiKa♦ Aug 29 '12 at 14:23
