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.
