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.
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
