Q1: Draw a sequence diagram to show the interaction perspective when a customer buys a camera over the online shopping website. Assume the following 6 objects in the system: - 1. Customer 2. Order System 3. Credit Card Company 4. Supplier 5. Warehouse 6. Courier Draw a diagram that models the following scenario. A customer places an order for a digital camera, and supplies credit card details and address etc. (You do not need to model the detail steps of making the order.) The System asks the Credit Card Company to authorise the transaction. (Assume it is successful.) The System checks if the camera is in stock in the warehouse (the System contains an inventory module).
