Can someone help me with this data flow diagram?
Here is the DFD: http://img97.imageshack.us/img97/6496/86249242.jpg
It looks like the customer first makes an enquiry to Marketing and then gets the catalogue, then t he customer makes the payment and gets the invoice, then gets sent the product from the ‘Manafacture’ data source, but why does the customer then send a product order to the ‘Ordering’ one?
Can someone explain this briefly?

don't need the data diagram. the flow is as follows;
inquiry to manufacturer
make selection and order the product
get sent an invoice
pay bill if all is wellSource(s): 30+ years in sales
