Hi! Today, I’ll share some thoughts on the simple ER diagram for the hotel management system.

This small database will also provide you with a thorough overview of the tables in the Hotel management system database project.

This course will teach you how to administer a hotel database and how to construct a database for a hotel management system.

You will get the ER diagram for the hotel management system with an explanation pdf and PPT files at the end of the talk, which will be useful for your DBMS studies.

To start with, I outlined below the topics to be covered in this article.

Hotel Management System ER Diagram Description

This ER Diagram of a hotel system was created using a hotel database design. The system’s job is to store and encode consumer data and transactions.

In addition, for reports and inventory purposes, the hotel administrator must have access to customer information.

Features of Hotel Management System ER Diagram

Time needed: 5 minutes

Here are the hotel management system features which were the basis for creating the database tables and ER Diagram design for project development.

Hotel Management
The core aspect of the system is Hotel Management, which manages the hotel’s basic information, including its basic data, accommodations, personnel, and services offered. This is the information that will be kept in the ER Diagram.
User Management
This feature is in charge of adding, updating, and deleting information for the user. The administrator or the owner, service crews or employees, and the client are examples of users. Each of them will have their basic information entered in the ER Diagram of the Hotel Management System.
Managing Reports
The hotel administrator is the only person who has access to all of the system’s transactions. Customers’ queries, reservations, services given, and many more transactions were part of these transactions.
Customer Reservation
Customer reservations require the customer’s basic information, such as name, address, and phone number, in order for hotel administrators to track their transactions anytime they use the hotel’s services.
Transaction and Reports Management
This feature will save customer transactions, including their details, as well as summaries of all transactions done by hotel staff and customers.
