Develop a Use case diagram for Grubhub
In addition to the normal stuff you do on Grubhub, the following assumptions apply:
1. Grubhub’s system connects to the online ordering system at each restaurant that you see
2. All payments to Grubhub are actually processed by PayPal; which does things like verify
the credit card, collect the payment data, and pay the restaurant and the delivery service
3. Grubhub’s system connects to Uber to arrange for and expedite deliveries
Use includes and extends in your diagram as needed to explicate how Grubhub works.
