Complete a decomposed lower level data flow diagram (DFD) for the following requirements for a customer posting payment to a store charge account. This is done by scratch using Microsoft Visio and based on the Gane and Sarson shapes as explained in the lesson and textbook (Chapter 6).

• The customer will send payment by mail and the payment will be posted through the system that updates the customer charge account.


• The payments have to be deposited systematically to the bank, recorded in the general ledger by the system, and the system should automatically send the customer a receipt.


• Your DFD should have two external entities, two data stores, and three processes.


• You should utilize Microsoft Visio to create this DFD.
