Instructions:
• You must submit two separate copies (one Word file and one PDF file) using the
Assignment Template on Blackboard via the allocated folder. These files must not be in
compressed format.
• It is your responsibility to check and make sure that you have uploaded both the correct files.

between words, hide characters, use different character sets, convert text into image or languages
other than English or any kind of manipulation).
• Email submission will not be accepted.
• You are advised to make your work clear and well-presented. This includes filling your information
on the cover page.
• You must use this template, failing which will result in zero mark.
• You MUST show all your work, and text must not be converted into an image, unless specified
otherwise by the question.
• Late submission will result in ZERO mark.

E-Commerce Inventory and Order Management System
Background: An emerging online retail company specializing in artisanal products
wants to develop a database system to manage its inventory, customer orders, and
shipping operations. The system should facilitate real-time inventory updates, order
processing, and customer management to enhance operational efficiency and customer
satisfaction.
Project Objective: Design and implement a database system for the e-commerce
platform that supports inventory tracking, order processing, and customer relationship
management. The system should be scalable, reliable, and secure, ensuring smooth
operations as the business grows.
Requirements:
1. Data Storage:
o Product information: Includes product ID, name, description, price, and
stock level.
o Customer information: Includes customer ID, name, contact details, and
order history.
o Orders: Details about customer orders, including order ID, product(s)
ordered, quantities, prices, and status.
o Shipping: Information on shipping logistics, such as tracking numbers,
shipping status, and delivery dates.
2. Project Deliverables:
o An Entity-Relationship (ER) diagram representing the database structure.
o A fully normalized database schema.
o Implementation of the database in a suitable DBMS.
By implementing a robust database system for the E-Commerce Inventory and Order,
the management can efficiently handle the operations from managing product inventory
to processing customer orders and handling shipping logistics.
