The online sales system of a store works as follows: For a customer to make a purchase, they must be previously registered and browse the store website selecting products. Then in order to purchase, a form must be completed. This purchase form consists of three parts: Customer data, payment method and the list of selected products. When the purchase is made, the system saves the operation with an identifier (order ID), the customer and the list of products purchased. Develop a conceptual design for such a system, highlighting its key characteristics and essential high-level requirements. 1. Include a graphical model of the system considering all components, from DB to GUI, don’t forget about costumers information.
