Introduction

The project is about the analysis of the students’ understanding in analyzing a given scenario and practical skills to apply concepts and build diagrams studied in IT242 (Software Engineering). The project consists of five parts. Students are required to answer all of these parts based on the below scenario.

“Choco Shop”, a shop that sells chocolates, is in the process of expanding its business. In order to achieve this plan, the “Choco Shop” management would like to start developing a WebApp with the following scenario:

The “Choco Shop” management wishes to have a WebApp that handles up to 100 users simultaneously, and uses lots of animation. Users should be able to view the available chocolate items and if they would like to be customers they have to register in the system. When a customer creates an account, the customer login credentials (username and password) must be chosen. After logging to the system, customers can search for available items, order items, pay online after providing the credit card information, and they are able to write their feedback. The WebApp should verify the login credentials such as the user name and password. The system verifies the credit card information and, if approved, the order is finalized, and the system sends a confirmation message to the customer.

The “Choco Shop” employee is responsible for managing the customer orders, adding items, deleting items, and updating the customer information. The employees will be able to do the activities only after logged into the system. The “Choco Shop” administrator can check the status of the online orders, check inventory, send a request to a supplier, update the inventory, and update suppliers’ information in the database. The administrator will be able to do the activities only after logged into the system. The supplier can add new chocolate items and add details of special discount offers. The supplier will be able to do the activities only after logged into the system. The “Choco Shop” management would like to have a system that allows the customers to pay in different currencies.
