Database Design for Spotify Premium System Design
Creating a database model for a Spotify-like platform, covering important features like user management, playlist creation, artist following, track liking, premium features, and payment systems.
6.1. User Information
Here we store important details like user names, emails, passwords, birth dates, and profile pictures. We’ll also include a feature to identify whether users are regular or premium members.
CREATE TABLE Users (
User_ID INT AUTO_INCREMENT PRIMARY KEY,
Name VARCHAR(50) NOT NULL,
Email VARCHAR(50) NOT NULL UNIQUE,
Password VARCHAR(100) NOT NULL,
Date_of_Birth DATE,
Profile_Image Blob,
User_Type VARCHAR(10) NOT NULL DEFAULT 'regular'
);
6.2. Premium User Features
There are special features for premium users, like ad-free listening. These features will be stored in a table, and we’ll use another table to connect users with their chosen premium features.
CREATE TABLE Premium_Feature (
Premium_Feature_ID INT PRIMARY KEY AUTO_INCREMENT,
Name VARCHAR(50) NOT NULL
);
CREATE TABLE User_Premium_Feature (
User_ID INT,
Premium_Feature_ID INT,
PRIMARY KEY (User_ID, Premium_Feature_ID),
FOREIGN KEY (User_ID) REFERENCES Users(User_ID),
FOREIGN KEY (Premium_Feature_ID) REFERENCES Premium_Feature(Premium_Feature_ID)
);
6.3. Payment Integration
To handle payments, we’ll set up tables to store payment details and subscription plans. Another table will link users with their chosen subscription plans.
CREATE TABLE Payment (
Payment_ID INT PRIMARY KEY AUTO_INCREMENT,
User_ID INT NOT NULL,
Payment_Method VARCHAR(50) NOT NULL,
Payment_Date DATE NOT NULL,
Amount DECIMAL(10, 2) NOT NULL,
FOREIGN KEY (User_ID) REFERENCES Users(User_ID)
);
CREATE TABLE Subscription_Plan (
Subscription_Plan_ID INT PRIMARY KEY AUTO_INCREMENT,
Name VARCHAR(50) NOT NULL,
Price DECIMAL(10, 2) NOT NULL,
Description VARCHAR(500) NOT NULL
);
CREATE TABLE User_Subscription_Plan (
User_ID INT,
Subscription_Plan_ID INT,
Start_Date DATE NOT NULL,
End_Date DATE NOT NULL,
PRIMARY KEY (User_ID, Subscription_Plan_ID),
FOREIGN KEY (User_ID) REFERENCES Users(User_ID),
FOREIGN KEY (Subscription_Plan_ID) REFERENCES Subscription_Plan(Subscription_Plan_ID)
);
6.4. Artists Table
This table keeps track of artists’ basic details like their names, genres, and images. It helps organize and display information about various artists on the platform.
CREATE TABLE Artists (
Artist_ID INT AUTO_INCREMENT PRIMARY KEY,
Name VARCHAR(50) NOT NULL,
Genre VARCHAR(50),
Image_URL VARCHAR(255)
);
6.5. Albums Table
In this table, we store information about albums, such as their names, release dates, and cover images. It helps users find and explore different albums easily.
CREATE TABLE Albums (
Album_ID INT AUTO_INCREMENT PRIMARY KEY,
Artist_ID INT,
Name VARCHAR(50) NOT NULL,
Release_Date DATE,
Image VARCHAR(255),
FOREIGN KEY (Artist_ID) REFERENCES Artists(Artist_ID)
);
6.6. Tracks Table
Tracks Table stores details about individual songs, including their names, durations, and file locations. It’s essential for playing music and organizing songs within albums.
CREATE TABLE Tracks (
Track_ID INT AUTO_INCREMENT PRIMARY KEY,
Album_ID INT,
Name VARCHAR(50) NOT NULL,
Duration INT NOT NULL,
Path VARCHAR(255),
FOREIGN KEY (Album_ID) REFERENCES Albums(Album_ID)
);
6.7. Playlists Table
This table helps users create and manage playlists by storing their names and associated user IDs. It’s where users organize their favorite songs into custom collections.
CREATE TABLE Playlists (
Playlist_ID INT AUTO_INCREMENT PRIMARY KEY,
User_ID INT,
Name VARCHAR(50) NOT NULL,
Image Blob,
FOREIGN KEY (User_ID) REFERENCES Users(User_ID)
);
6.8. Playlist_Tracks Table
Playlist_Tracks Table connects playlists with tracks, allowing users to add songs to their playlists. It keeps track of the order of songs within each playlist.
CREATE TABLE Playlist_Tracks (
Playlist_ID INT,
Track_ID INT,
`Order` INT,
PRIMARY KEY (Playlist_ID, Track_ID),
FOREIGN KEY (Playlist_ID) REFERENCES Playlists(Playlist_ID),
FOREIGN KEY (Track_ID) REFERENCES Tracks(Track_ID)
);
6.9. Followers Table
This table manages the relationship between users and artists, showing which artists a user follows. It helps users stay updated with their favorite artists’ latest releases.
CREATE TABLE Followers (
User_ID INT,
Artist_ID INT,
PRIMARY KEY (User_ID, Artist_ID),
FOREIGN KEY (User_ID) REFERENCES Users(User_ID),
FOREIGN KEY (Artist_ID) REFERENCES Artists(Artist_ID)
);
6.10. Likes Table
Likes Table keeps track of which songs users have liked, helping personalize their music recommendations. It’s useful for understanding user preferences and improving recommendations.
CREATE TABLE Likes (
User_ID INT,
Track_ID INT,
Like_Date_Time DATETIME,
PRIMARY KEY (User_ID, Track_ID),
FOREIGN KEY (User_ID) REFERENCES Users(User_ID),
FOREIGN KEY (Track_ID) REFERENCES Tracks(Track_ID)
);
