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

With the development of modern transportation networks, people are increasingly relying on online ticket booking services. In order to ensure the normal operation of the online ticket booking function, we need to design a maintainable MySQL table structure.

Before designing the database table structure, we need to clarify the requirements and business processes for the online ticket booking function. Depending on the needs, we can divide the main information of the ticket booking function into the following parts: flight information, passenger information and order information.

First, we can create a table named "flights" to store flight information. The table can contain the following fields:

• flight_id: flight ID, primary key
• airline: affiliated airline
• departure_city: departure city
• arrival_city : Arrival city
• departure_time: Departure time
• arrival_time: Arrival time
• price: Price
• seat_number: Number of seats
• create_time: Creation time
• update_time: Update time

Next, we can create a table named "passengers" to store passenger information. The table can contain the following fields:

• passenger_id: Passenger ID, primary key
• name: Name
• email: Email
• phone_number: Phone Number
• create_time: Creation time
• update_time: Update time

Finally, we can create a table named "orders" to store order information. The table can contain the following fields:

• order_id: order ID, primary key
• flight_id: flight ID, foreign key related to the "flights" table
• passenger_id: passenger ID, foreign key associated with the "passengers" table
• order_date: order date
• status: order status (for example: pending payment, paid, canceled, etc.)
• create_time: creation time
• update_time: update time

The above is a basic table structure design. According to actual needs, some other fields can also be added to meet specific business needs, such as baggage quantity, cabin type, etc.

The following is the SQL code of a table structure example:

CREATE TABLE flights (
  flight_id INT PRIMARY KEY AUTO_INCREMENT,
  airline VARCHAR(255),
  departure_city VARCHAR(255),
  arrival_city VARCHAR(255),
  departure_time DATETIME,
  arrival_time DATETIME,
  price DECIMAL(10, 2),
  seat_number INT,
  create_time DATETIME DEFAULT CURRENT_TIMESTAMP,
  update_time DATETIME DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP
);

CREATE TABLE passengers (
  passenger_id INT PRIMARY KEY AUTO_INCREMENT,
  name VARCHAR(255),
  email VARCHAR(255),
  phone_number VARCHAR(20),
  create_time DATETIME DEFAULT CURRENT_TIMESTAMP,
  update_time DATETIME DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP
);

CREATE TABLE orders (
  order_id INT PRIMARY KEY AUTO_INCREMENT,
  flight_id INT,
  passenger_id INT,
  order_date DATETIME,
  status VARCHAR(20),
  create_time DATETIME DEFAULT CURRENT_TIMESTAMP,
  update_time DATETIME DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
  FOREIGN KEY (flight_id) REFERENCES flights(flight_id),
  FOREIGN KEY (passenger_id) REFERENCES passengers(passenger_id)
);

Through the above table structure design, we can establish a maintainable MySQL database to realize the online ticket booking function. According to business needs, we can add, delete and modify tables to meet different functional requirements.

Of course, this is just a basic table structure design. Actual projects may need to consider more factors, such as data indexing, performance optimization, etc. In the actual development process, we also need to make appropriate adjustments and optimizations based on specific business needs.
