Sample Queries

Find All Bookings for a Specific Tourist

SELECT b.booking_id, t.first_name, p.package_name, b.booking_date
FROM Bookings b
JOIN Tourists t ON b.tourist_id = t.tourist_id
JOIN TourPackages p ON b.package_id = p.package_id
WHERE t.email = 'tourist@example.com';

Top 5 Most Booked Destinations

SELECT d.name, COUNT(b.booking_id) AS booking_count
FROM Destinations d
JOIN TourPackages p ON d.destination_id = p.destination_id
JOIN Bookings b ON p.package_id = b.package_id
GROUP BY d.destination_id
ORDER BY booking_count DESC
LIMIT 5;

Calculate Total Revenue by Hotel

SELECT h.hotel_name, SUM(b.total_amount) AS total_revenue
FROM Hotels h
JOIN Bookings b ON h.hotel_id = b.hotel_id
WHERE b.payment_status = 'Completed'
GROUP BY h.hotel_id
ORDER BY total_revenue DESC;

---

Normalization Approach

The database design follows Third Normal Form (3NF) principles:

First Normal Form (1NF)

• All columns contain atomic values
• No repeating groups
• Each row uniquely identifiable

Second Normal Form (2NF)

• Meets 1NF requirements
• All non-key attributes fully dependent on primary key
• No partial dependencies

Third Normal Form (3NF)

• Meets 2NF requirements
• No transitive dependencies
• All attributes depend only on primary key

This normalization eliminates data redundancy and ensures data integrity throughout the system.

• Basic understanding of SQL

Setup Steps

1. Clone the repository:

git clone https://github.com/MuhammadYasir85a/Tourism-Management-System-Database-Design-.git
cd Tourism-Management-System-Database-Design-

2. Open MySQL Workbench (or your preferred client)

3. Create a new database:

CREATE DATABASE tourism_management;
USE tourism_management;

4. Run the schema scripts in order:

mysql -u root -p tourism_management < schema/create_tables.sql
mysql -u root -p tourism_management < schema/constraints.sql
mysql -u root -p tourism_management < schema/insert_sample_data.sql

5. Test with sample queries:

mysql -u root -p tourism_management < queries/basic_queries.sql
