Question

Draw 1) a context data flow diagram (level-0) and 2) a level-1 diagram that shows the appropriate details for the system described below:

The Memphis Logistics Company is in the process of developing a new inventory management (IM) system.  The IM system is capable of handling data concerning shipments from suppliers and managing inventory management data.  When shipments are sent and received, the supplier enters shipment data into the IM system, and the IM system receives and records the formatted shipment data into a file called “inventory on hand”.  The warehouse manager is able to generate daily inventory reports using the data stored in “inventory on hand”.   Suppliers also send an invoice using the IM system, and the invoice is saved into a file called “invoice file”. The warehouse managers can view the invoices stored in “invoice file”. The inventory manager also makes payments to suppliers using the IM system.  Specifically, the inventory manager generates a payment using the IM system, and the IM system connects to an external banking site to verify the payment.  Once the verification is received by the IM system, and the IM system sends the verified payment to suppliers.  Lastly, when a new sale is made (data related to sales is handled by another system and is outside the scope of the IM system), the sales manager uses the IM system to update the record stored in “inventory on hand”.
