How can PHP beginners ensure proper data normalization in their database design?

Proper data normalization in a database design involves organizing data into separate tables to reduce redundancy and improve data integrity. PHP beginners can ensure proper data normalization by following normalization rules such as eliminating repeating groups, ensuring each table serves a single purpose, and establishing relationships between tables using primary and foreign keys. 

// Example PHP code snippet for creating normalized tables in a database
CREATE TABLE users (
    id INT PRIMARY KEY,
    username VARCHAR(50) NOT NULL,
    email VARCHAR(100) NOT NULL
);

CREATE TABLE user_roles (
    id INT PRIMARY KEY,
    user_id INT,
    role VARCHAR(50) NOT NULL,
    FOREIGN KEY (user_id) REFERENCES users(id)
);
