For the Flight Booking System backend, I've created several microservices: Authentication: Manages user login and access Flight Search: Finds available flights based on user input. Booking: Handles reservations, modifications, and cancellations. Payment: Processes secure transactions. Inventory: Manages flight availability, seats, and pricing. Notifications: Sends booking updates via email, SMS, etc. Customer Profiles: Stores and manages user information. Feedback & Ratings: Allows customers to give post-flight feedback. Analytics & Reporting: Gathers data for business insights. Integration: Connects with external systems (e.g., third-party APIs). This setup provides a scalable, modular backbone for your Flight Booking System. After the backend, I'll integrate it with a React front-end for a complete user experience.
