Hotel Management System in Python | Tkinter GUI & SQLite

 

Hotel Management System

 

 

 

The Hotel Management System is a Python-based application designed to handle various aspects of managing a hotel, such as guest registration, room booking, billing, check-in/check-out, and displaying customer information. The system is implemented using the Tkinter library for GUI design and SQLite for database management. 

 

 

 

Core Features

 

Guest Registration:

• Collects guest details: name, phone, ID proof, and address.
• Stores the data in the guests database table.
• Provides form validation to ensure all fields are filled before submission.

 

 

 

Room Booking:

• Allows booking rooms for registered guests.
• Supports different room types (Single, Double, Suite).
• Calculates the total price based on room type and duration of stay.
• Records booking information in the bookings database table.

 

 

 

 

 

Billing System:

• Fetches guest details and booking information for generating a bill.
• Displays guest name, phone number, room type, days of stay, and total price.

 

 

 

Check-In/Check-Out:

• Tracks whether a guest is currently checked in or out.
• Updates the checked_in status of a guest in the database.

 

 

 

Customer List and Editing:

• Displays all registered customers in a tabular format using Treeview.
• Enables editing of guest details (name, phone number).
• Updates the database with changes made to guest records.

 

 

 

 

Technologies Used

 

GUI Framework:

• Tkinter: Used for building the graphical user interface, including widgets such as buttons, labels, entry fields, and tables.

 

Database Management:

• SQLite: A lightweight relational database used for storing and retrieving application data. Two tables are used:
  • guests: Stores guest information (e.g., name, phone, ID proof, and address).
  • bookings: Stores booking details (e.g., guest ID, room type, duration, and price).

 

Python Libraries:

• sqlite3: Manages the connection between the application and the SQLite database.
• tkinter.ttk: Provides advanced widgets like Treeview and Combobox.
• messagebox: Displays alerts and confirmation messages.

How the Code Works

Initialization:

• The main window is created using Tkinter.
• Database connection is established, and tables are created if they don't exist.

 

Navigation and Frames:

• A side menu contains buttons for navigating between different modules (e.g., Guest Registration, Room Booking).
• A main_frame dynamically updates to display the content of the selected module.

 

Database Interactions:

• SQL queries are used to insert, update, and fetch data from the database.
• Foreign key relationships link guests and bookings tables.

 

Form Validation:

• User inputs are validated to ensure correctness (e.g., all fields are required, numerical checks for certain fields).

 

Dynamic UI Updates:

• Widgets in the main_frame are dynamically destroyed and recreated based on user actions.

 

Key Benefits

• Modular Design: Each functionality (e.g., registration, booking) is implemented as a separate method, making the code maintainable.
• Ease of Use: The GUI provides an intuitive interface for hotel staff.
• Scalability: Additional features (e.g., inventory management, advanced reports) can be integrated into the existing framework.

 

This Hotel Management System is a beginner-friendly yet robust solution for managing small to medium-sized hotels. It demonstrates effective use of Python, GUI development, and database management in a real-world application.
