Design a Hotel Booking System

Functional Requirements:

• Users can search for hotels by location, dates, and number of guests.
• Users can view hotel details, including room types, prices, and amenities.
• Users can create an account and log in.
• Users can book available hotel rooms for specific dates.
• Users can view and manage their bookings (e.g., cancel a booking).
• The system must prevent double-booking of rooms.
• Users can securely pay for bookings using common payment methods (e.g., credit card).

Non-Functional Requirements:

• The system should be available 24/7 with minimal downtime.
• The system should handle moderate traffic (e.g., thousands of users searching and booking concurrently).
• Search and booking operations should respond within a few seconds.
• User and payment data must be securely stored and transmitted (e.g., encryption, PCI compliance).
• The system should be maintainable and allow for future feature additions.
• The user interface should be simple and intuitive.
