A pharmaceutical company receives orders from pharmacies at its sales department. The sales department prepares an internal order form sent to the warehouse and acknowledges the pharmacy. The internal order form data is stored in a database. The warehouse verifies item availability against stock data. For in-stock items, the order is prepared and shipping instructions are sent to the shipping department, which notifies the sales department and accounting department. The accounting department sends an invoice to the customer. Out-of-stock items are placed on backorder to be processed later by shipping.

Draw a Level-0 data flow diagram (DFD) showing the flow of information between the pharmacy, the pharmaceutical company, and various departments within the company.

The mark scheme is shown once you've answered.
