The business process starts with the user placing an order via the internet. The
system receives the order and checks the food storage for the availability of the
ingredients that are required for order preparation. The order is rejected, and the
user is informed about it in case ingredients are not available. Otherwise, the
system notifies the chef, and he starts the preparation of the order. Simultaneously
the payment is verified, and if the payment is successful, the system updates the
food storage database and then stores the bill in the system, which is then printed
for the customer. If not, the order is rejected. When the order is prepared, the
delivery staff packs the food along with the printed bill. Finally, the order is sent to
the customer.
