+# Grocery Store Database Setup
+
+## Overview
+
+These are instructions for setting up the grocery_store database along with sample data using SQL scripts.
+
+## Setup Instructions
+
+1. Create the `grocery_store` database:
+
+```sql
+CREATE DATABASE IF NOT EXISTS grocery_store;
+```
+
+2. Switch to the `grocery_store` database:
+
+```sql
+USE grocery_store;
+```
+
+3. Create the `uom` (unit of measure) table:
+
+```sql
+CREATE TABLE IF NOT EXISTS uom (
+    uom_id INT AUTO_INCREMENT PRIMARY KEY,
+    uom_name VARCHAR(50)
+);
+```
+
+4. Insert demo data into the `uom` table:
+
+```sql
+INSERT INTO uom (uom_name) VALUES
+('Piece'),
+('Kilogram'),
+('Liter');
+```
+
+5. Create the `products` table:
+
+```sql
+CREATE TABLE IF NOT EXISTS products (
+    product_id INT AUTO_INCREMENT PRIMARY KEY,
+    name VARCHAR(255),
+    uom_id INT,
+    price_per_unit DECIMAL(10, 2),
+    FOREIGN KEY (uom_id) REFERENCES uom(uom_id)
+);
+```
+
+6. Insert demo data into the `products` table:
+
+```sql
+INSERT INTO products (name, uom_id, price_per_unit) VALUES
+('Apples', 1, 1.99),
+('Milk', 3, 2.49),
+('Bread', 1, 3.99);
+```
+
+7. Create the `orders` table:
+
+```sql
+CREATE TABLE IF NOT EXISTS orders (
+    order_id INT AUTO_INCREMENT PRIMARY KEY,
+    customer_name VARCHAR(255),
+    total DECIMAL(10, 2),
+    datetime DATETIME
+);
+```
+
+8. Insert demo data into the `orders` table:
+
+```sql
+INSERT INTO orders (customer_name, total, datetime) VALUES
+('Rudraprasad Mohapatra', 15.97, NOW()),
+('Rajarudra Mohapatra', 8.98, NOW());
+```
+
+9. Create the `order_details` table with `ON DELETE CASCADE`:
+
+```sql
+CREATE TABLE IF NOT EXISTS order_details (
+    order_detail_id INT AUTO_INCREMENT PRIMARY KEY,
+    order_id INT,
+    product_id INT,
+    quantity INT,
+    total_price DECIMAL(10, 2),
+    FOREIGN KEY (order_id) REFERENCES orders(order_id),
+    FOREIGN KEY (product_id) REFERENCES products(product_id) ON DELETE CASCADE
+);
+```
+
+10. Insert demo data into the `order_details` table:
+
+```sql
+INSERT INTO order_details (order_id, product_id, quantity, total_price) VALUES
+(1, 1, 2, 3.98),
+(1, 2, 1, 2.49),
+(2, 3, 1, 3.99);
+```
+
+That's it! You have successfully set up the `grocery_store` database with sample data.
+
 ### Exercise 
 
 The grocery management system that we built is functional but after we give it to users for use, we got following feedback. The exercise for you to address this feedback and implement these features in the application,
