Consider this scenario: Quality Tools is a company that sells a
line of high-quality tools through an online store. When customers
place orders on the company’s website, the system checks to see if
the items are in stock, issues a status message to the customer,
and generates a shipping order to the warehouse, which fills the
order. The system automatically bills the customer when the order
ships. The system also produces various reports.

I need help with the following activities for the above
scenario:

(1) Draw a context diagram for the order system.

(2) Draw a Level 0 DFD for the order system.

(3) Justify the choices you made in your context diagram and
DFD.

Thank you.
