Best Practices

Security

-- Use parameterized queries
PREPARE stmt FROM 'SELECT * FROM users WHERE id = ?';
EXECUTE stmt USING @user_id;

-- Limit user permissions
CREATE USER 'app_user'@'localhost' IDENTIFIED BY 'password';
GRANT SELECT, INSERT, UPDATE ON myapp.* TO 'app_user'@'localhost';

Performance

-- Use indexes effectively
CREATE INDEX idx_user_email ON users(email);
CREATE INDEX idx_order_date ON orders(created_at);

-- Analyze query performance
EXPLAIN SELECT * FROM users WHERE email = 'user@example.com';

Development Workflow

# Database development workflow
# 1. Design schema
# 2. Create migrations
# 3. Test with sample data
# 4. Deploy to staging
# 5. Deploy to production

# Use environment-specific configurations
# development: local database
# staging: staging database
# production: production database

Conclusion
