SQL and Databases

This course is designed for students and recent graduates who want to work independently with databases (without getting lost in theory).

You’ll learn the practical core:

• SELECT / FROM
• filtering with WHERE (including NULL)
• how to combine tables with JOIN
• and finally, reporting logic with GROUP BY and sorting with ORDER BY

The course is divided into short modules with small exercises and quizzes, so you can continuously check your understanding. You can follow the standard track step by step — or use an optional fast-track shortcut if you already know the basics.
