How to design an efficient MySQL table structure to implement the music playback function?

When designing a database table structure that can efficiently implement the music playback function, we need to consider the following important factors: data consistency, query speed and scalability. The following will introduce in detail how to design this table structure and give some specific code examples.

First, we need to create two main tables: the song table and the user table. The song table will store song-related information, while the user table is used to store user information, such as username, password, etc.

The following is an example of a simple song table:

CREATE TABLE songs (
  id INT PRIMARY KEY AUTO_INCREMENT,
  title VARCHAR(100) NOT NULL,
  artist VARCHAR(100) NOT NULL,
  album VARCHAR(100) NOT NULL,
  duration INT NOT NULL,
  file_path VARCHAR(255) NOT NULL,
  created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
  updated_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP
);

In this table, we use the auto-incremented id field as the primary key to ensure that each song has a unique identifier . Secondly, we store important information such as the song's title, artist, album, duration, and file path. At the same time, we also added created_at and updated_at fields to record the creation and update time of data.

Next, we can create a user table to store user-related information, as shown below:

CREATE TABLE users (
  id INT PRIMARY KEY AUTO_INCREMENT,
  username VARCHAR(100) NOT NULL,
  password VARCHAR(100) NOT NULL,
  created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
  updated_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP
);

In this table, we also use the auto-incremented id field as The primary key also stores user information such as user name and password.

In order to implement the music playback function, we also need an association table to store the relationship between users and songs. This association table can record the user's favorite songs, playback history and other information.

The following is a simple example of a related table of songs that users like:

CREATE TABLE user_songs (
  id INT PRIMARY KEY AUTO_INCREMENT,
  user_id INT,
  song_id INT,
  created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
  FOREIGN KEY (user_id) REFERENCES users(id),
  FOREIGN KEY (song_id) REFERENCES songs(id)
);

In this related table, we use the auto-incremented id field as the primary key, and add user_id and song_id Fields to associate the user table and song table respectively. At the same time, we also added the created_at field to record the time when the song was liked.

Through the above table structure design, we can implement some basic functions, such as adding songs, creating users, recording users' favorite songs, etc. Here are some specific code examples:

1. Insert a new song:

   INSERT INTO songs (title, artist, album, duration, file_path)
   VALUES ('My Song', 'John Doe', 'My Album', 180, '/path/to/my_song.mp3');

   Copy after login

2. Create a new user:

   INSERT INTO users (username, password)
   VALUES ('admin', 'password123');

   Copy after login

3. The user likes a song:

   INSERT INTO user_songs (user_id, song_id)
   VALUES (1, 1);

   Copy after login

   The above is a simple and basic database table structure design, which can realize the function of music playback. You can further expand and optimize this table structure according to actual needs, such as adding user comment tables, creating playlists, etc. In short, reasonable database table structure design can improve query efficiency and data consistency, and provide a good foundation for realizing the music playback function.
