Description
Hi! I need help with a university project for my IT244 – Introduction to Database course. The project is about building a database for an E-Commerce Inventory and Order Management System.
Here’s what I need the tutor to do:
- Identify entity types, attributes, and keys
- Define relationships and cardinalities
- Draw the ER diagram
- Write schemas (before and after normalization)
- Create the normalized tables using SQL
- Insert at least 5 sample rows in each table
- Write and execute 6 SQL queries as described in the project file
Please use standard SQL (e.g., MySQL or Oracle syntax). Make sure the work follows the instructions in the file carefully and is well-presented.
Let me know if anything is unclear. Thanks!

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.
• The work should be your own, copying from students or other resources 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.

e) Schemas after the normalization
f) Create the normalized tables, write the necessary SQL statements to create the
tables.
g) Insert at least five rows into each table.
h) Write SQL queries to find the following:
1. List all products currently out of stock to check for products that need
restocking, helping manage inventory efficiently.
2. Find total sales per product to help analyze which products are generating
the most revenue, aiding in strategic business decisions.
3. Identify orders that are delayed to proactively address delays and
communicate with affected customers.
4. List Customers who have placed more than three orders to identify top
customers, which can be targeted for special offers or loyalty programs.
5. Calculate Inventory Value to provide the total value of all items currently
in stock, this is crucial for financial reporting and inventory management.
6. Show Detailed Information for all orders placed today to provide a
snapshot of the day’s business activities.
