This sequence diagram outlines the interactions in a car rental system. A customer initiates by searching for cars on the rental website, which fetches available cars from the car database. The rental website then displays these cars to the customer. Once the customer selects a car and provides details, the rental website verifies these via a verification system. Upon confirmation, the booking system confirms the booking, and the rental website sends a confirmation to the customer. Notes highlight the need for valid customer details and the necessity for the rental website to confirm the booking process.
