In what ways can PHP developers normalize their database structure to improve efficiency when calculating player ranking data?

To improve efficiency when calculating player ranking data, PHP developers can normalize their database structure by breaking down data into smaller, related tables and establishing relationships between them. This can help reduce redundancy, improve data integrity, and make queries more efficient. 

// Example of normalizing database structure for player ranking data

// Players table
CREATE TABLE players (
    id INT PRIMARY KEY,
    name VARCHAR(50)
);

// Scores table
CREATE TABLE scores (
    id INT PRIMARY KEY,
    player_id INT,
    score INT,
    FOREIGN KEY (player_id) REFERENCES players(id)
);

// Query to get player's total score
SELECT players.name, SUM(scores.score) AS total_score
FROM players
JOIN scores ON players.id = scores.player_id
GROUP BY players.id;
