Creating an advanced-level Hotel Management System (HMS) with Flask and Bootstrap 5 involves designing a robust database structure, implementing backend logic, and creating responsive frontend pages. Below is a detailed implementation:
Database Structure
The database will be designed using SQLAlchemy (ORM for Flask). Here's the schema:
Tables
- Users: Stores user information (guests, staff, and admins).
- Guests: Stores guest information.
- Staff: Stores staff information.
- Rooms: Stores room details.
- Bookings: Stores booking details.
- Payments: Stores payment details.
- Services: Stores hotel services (e.g., spa, restaurant).
