The MariaDB Test is a hands-on challenge designed to simulate the scenarios you’ll face when managing relational databases at scale. Each question pushes you to combine technical accuracy with strategic decision-making, ensuring you can handle complexity without sacrificing performance or security.
You’ll be evaluated across four key competencies essential for advanced MariaDB professionals:
SQL Querying & Data Manipulation
Craft optimized queries, work with joins and subqueries, and ensure data accuracy through precise data manipulation.
Database Design & Data Integrity
Apply normalization rules, define relationships, and use constraints and indexes to keep data both structured and reliable.
Database Administration & Security
Manage user permissions, configure secure connections, and implement backup and recovery strategies to safeguard critical information.
Advanced Programming & Error Handling
Utilize stored procedures, triggers, and error-handling logic to automate workflows and maintain system stability under load.
This is where theory meets execution — and where your ability to solve real database challenges is put to the test.
