Airline/GetSetFly is a backend project developed for managing flight bookings and notifications using a microservices architecture. It consists of several services built with Node.js, Express.js, and MySQL's Sequelize ORM. The project follows best practices for backend development, including role-based authorization, rate-limiting, and message queuing for efficient communication between services.

• Entry point for accessing all other services
• Implements authentication and role-based authorization
• Uses Proxy for redirecting requests/API calls to the appropriate service
• Implements rate-limiting to prevent server overload

• Provides information about flights, airplanes, cities, and airports
• Supports CRUD operations for flights
• Implements associations for tables related to flights, airplanes, cities, and airports
• Allows users to filter flights based on various criteria including price, available seats, departure and arrival airports.
• Leverages the power of SQL queries to efficiently filter flight data based on the provided criteria. It utilizes Sequelize ORM's query-building capabilities to construct dynamic queries and retrieve relevant flight information from the database.

• Allows authenticated users, admins, and flight companies to book tickets
• Publishes events to the Message Queue after successful booking
• Prevents multiple payments from the same user using transactional queries and RabbitMQ's Pub/Sub architecture

• Sends email notifications to customers after successful ticket bookings
• Acts as a Subscriber to the events published by the Booking Service via message queues

• Microservices Architecture: Scalable and maintainable architecture with separate services for different functionalities.
• Authentication and Authorization: Role-based access control for securing resources.
• Rate Limiting: Prevents server overload by restricting the number of requests per IP address.
• Message Queues: Efficient communication between services using RabbitMQ's Pub/Sub architecture.
• Transactional Queries: Prevents concurrency issues during ticket booking by using transactional queries provided by MySQL.
• Association: Utilizes associations in the database schema to represent relationships between entities.
