Case Study: Movie Booking System

🎯 Problem Statement

Managing theater seat reservations requires handling concurrent requests and ensuring strong transactional integrity to prevent double-booking. The goal was to build a full-stack booking system with complex relationships and robust administrative controls.

🏗️ Architecture Overview

The system follows an MVC architecture built on Laravel, utilizing Eloquent ORM for complex database relationships.

• Frontend: Blade templates with Bootstrap.
• Backend: Laravel handling routing, session management, and business logic.
• Database: MySQL with relational integrity enforced via foreign keys.

🛠️ Tech Stack

• Language: PHP 8
• Framework: Laravel 10
• Database: MySQL
• Auth: Laravel Breeze (Customized)

🔒 Security Considerations

• Concurrency Control: Utilized database transactions and pessimistic locking (lockForUpdate) during seat reservation logic.
• Access Control: Implemented Role-Based Access Control (RBAC) via custom Middleware to separate Admin dashboard from User views.
• Data Protection: CSRF tokens enforced on all state-changing requests, and mass assignment protections configured on Eloquent models.

🧩 Challenges Solved

1. Double Booking: Addressed race conditions in seat reservations by enforcing strict database locks during the booking transaction.
2. Dynamic UI Updates: Handled complex state management in the Blade views for seat selection.

📈 Lessons Learned

This project highlighted the importance of ACID properties in relational databases and how framework-level tools like Laravel’s Eloquent simplify complex data relationships while maintaining security.
