Best Practices

Create a dedicated MySQL user with SELECT-only permissions to prevent accidental data modification.
    CREATE USER 'julius_readonly'@'%' IDENTIFIED BY 'secure_password';
    GRANT SELECT ON your_database.* TO 'julius_readonly'@'%';
Verify your connection works correctly using a development or staging database before connecting to production.
Work with your database administrator to ensure proper security policies and performance guidelines are followed.
Keep an eye on database load when running complex queries through Julius, especially on production systems.
