Answer 1

The task is to draw a use case diagram for Noon KSA, identifying interactions between customers, suppliers, and the system, highlighting the creation of profiles, ordering and uploading products, payment management, and viewing statistics.

Step-by-step explanation:

The student's task is to draw a use case diagram for the Noon KSA service platform, which involves various interactions between customers, suppliers, and the system itself. In this scenario, the customers and suppliers are stakeholders, as their requirements and activities need to be captured by the use case diagram.

Both customer and supplier must create profiles and go through an authentication process before engaging with the service. Suppliers are responsible for uploading products with all necessary details, as well as managing sales and reviewing statistics.

On the other hand, customers can order products, choose a payment method, and manage their orders. The third party in this use case diagram would be the Bank's Online-Payment system which handles the payment transactions.

Key Actors in the Use Case Diagram

• Supplier
• Online Payment System (Bank)

Customers are represented in the use case diagram as they can create a profile, order products, choose payment methods, cancel orders, and edit order lists. Suppliers are also represented as they upload products, specify sales, manage orders, and view product statistics. The Online Payment System actor is included to represent the payment management aspect.
