How to design a maintainable MySQL table structure to implement the online hotel booking function?

In implementing the function of online hotel booking, it is very important to reasonably design the database table structure. A good table structure can improve the performance and maintainability of the system. This article will introduce how to design a maintainable MySQL table structure to implement the online hotel booking function, and provide specific code examples.

1. Hotel table (hotel)

The hotel table is used to store basic information of the hotel, such as hotel ID, hotel name, address, phone number, etc. Additionally, additional fields can be added as needed, such as hotel type, star rating, etc.

The SQL statement to create the hotel table is as follows:

CREATE TABLE hotel (
hotel_id INT AUTO_INCREMENT PRIMARY KEY,
name VARCHAR(255),
address VARCHAR(255),
phone VARCHAR(20),
-- 其他字段
);

2. Room type table (room_type)

The room type table is used to store information of different room types , such as single rooms, double rooms, suites, etc. Each room type will have a unique identifier (ID), along with information such as the room type's name, description, and price.

The SQL statement to create a room type table is as follows:

CREATE TABLE room_type (
room_type_id INT AUTO_INCREMENT PRIMARY KEY,
name VARCHAR(255),
description TEXT,
price DECIMAL(10,2),
-- 其他字段
);

3. Room table (room)

The room table is used to store specific room information, and Relationship between room and hotel. Each room has a unique room number, hotel ID, room type ID and other information.

The SQL statement to create the room table is as follows:

CREATE TABLE room (
room_id INT AUTO_INCREMENT PRIMARY KEY,
room_number INT,
hotel_id INT,
room_type_id INT,
-- 其他字段
FOREIGN KEY (hotel_id) REFERENCES hotel(hotel_id),
FOREIGN KEY (room_type_id) REFERENCES room_type(room_type_id)
);

4. Reservation table (reservation)

The reservation table is used to track the reservation status of hotel rooms. Each reservation will have a unique reservation ID, reservation date, check-out date, booker ID and other information.

The SQL statement to create the reservation table is as follows:

CREATE TABLE reservation (
reservation_id INT AUTO_INCREMENT PRIMARY KEY,
start_date DATE,
end_date DATE,
customer_id INT,
room_id INT,
-- 其他字段
FOREIGN KEY (customer_id) REFERENCES customer(customer_id),
FOREIGN KEY (room_id) REFERENCES room(room_id)
);

The above is a simple database table structure design example, used to implement the function of online hotel booking. Based on actual needs, this design can be expanded and other required tables and fields added.

To improve system performance, you can create indexes on appropriate fields and optimize query statements. For example, you can create indexes on the room_id and customer_id fields of the reservation table to speed up queries.

Methods to maintain this table structure include regularly backing up the database, regularly verifying and updating indexes, using appropriate data types and field lengths, and regularly optimizing query statements.

It should be noted that the above code is only an example and needs to be adjusted and modified according to specific needs in actual applications.
