This sequence diagram outlines the process flow of an online food ordering system. It begins with the customer selecting a restaurant, triggering the Online Food Ordering System to fetch the menu from the Restaurant Database. Once retrieved, the system displays the menu to the customer. The customer then places an order, which is sent to the restaurant. After confirmation, the customer makes a payment, verified by the Payment Gateway. Upon successful verification, the system confirms the payment, and the customer receives a payment confirmation. Finally, the customer receives the order through a delivery person.

About sequence diagrams
