How can PHP developers simplify their database schema while still maintaining data integrity for a music website project?

To simplify the database schema for a music website project while maintaining data integrity, PHP developers can utilize foreign key constraints and normalization techniques. By properly structuring the database tables and relationships, developers can reduce redundancy and improve overall efficiency.

CREATE TABLE artists (
    artist_id INT PRIMARY KEY,
    artist_name VARCHAR(50) NOT NULL
);

CREATE TABLE albums (
    album_id INT PRIMARY KEY,
    album_name VARCHAR(50) NOT NULL,
    artist_id INT,
    FOREIGN KEY (artist_id) REFERENCES artists(artist_id)
);

CREATE TABLE songs (
    song_id INT PRIMARY KEY,
    song_title VARCHAR(50) NOT NULL,
    album_id INT,
    FOREIGN KEY (album_id) REFERENCES albums(album_id)
);
