Relational Database Certification

What this course covers

SQL is one of the most durable, in-demand technical skills out there, and freeCodeCamp's Relational Database Certification takes a hands-on approach to teaching it rather than just talking through syntax on slides.

Who it's for

Beginners to databases, aspiring backend developers, and anyone in a data-adjacent role who keeps hearing “just write a query” and wants to actually be able to do that. As with freeCodeCamp's other certifications, it's free and self-paced, so there's no barrier to starting today.

Relational databases underpin a huge share of the software running behind the scenes of everyday apps, which makes SQL one of those rare skills that stays relevant across job titles — analyst, developer, product manager, or founder all eventually need to pull their own data.

Why grab it: a free, hands-on certification in a skill this transferable is hard to pass up, especially with no cost or time limit attached.
