About this course

freeCodeCamp's Relational Database certification is the most hands-on in its catalog — everything runs in a virtual Linux environment directly in VS Code, with exercises in PostgreSQL, SQL querying, bash scripting, and Git. It's one of the newer certifications and uses an interactive tutorial format that gives immediate feedback on each command rather than a project-submit structure.

It fills a gap in the freeCodeCamp curriculum: the other certifications cover web development and programming but don't go deep on the relational database layer that most backend systems are built on. PostgreSQL is the industry's preferred open-source relational database, making this the right free credential for anyone who uses SQL in a back-end or data context.

What you'll learn

Create and query PostgreSQL databases using SQL

Design normalized relational database schemas

Write bash scripts for data processing and automation

Use Git for version control in a Linux environment

Manage PostgreSQL users, permissions, and stored procedures

Frequently asked questions

The interactive Linux/VS Code environment with PostgreSQL gives hands-on command-level practice rather than a web-based SQL sandbox — more similar to how you'd actually work with a database on a real server.

PostgreSQL is the most capable open-source relational database and is widely preferred in production environments over MySQL for new projects.
