Our approach

Labs are the product.
Theory exists to prepare you.

Most training platforms deliver content through video lectures and multiple-choice questions. Datanerves gives you a real Linux server, a real PostgreSQL database, and real engineering problems — graded against the actual state of your environment.

Automated grading
Real isolated environments
Each student gets their own Rocky Linux 9 container with PostgreSQL 16. No shared sandboxes. No simulations.
Automated grading
Ansible playbooks inspect the actual database state. Either the index exists or it does not. Pass or fail, immediately.
Production datasets
FinTrack: 16.5M rows across accounts, transactions, and users. Real query plans. Real performance problems.
Structured paths
Theory, guided exercise, then practice lab — in that order, for every chapter. Always know where you are.
Browser terminal
No SSH setup. No local installation. Open your lab and type directly into a real Linux shell from any browser.
5 languages
Content in English, French, Arabic, Spanish, and German. Arabic renders right-to-left automatically. Switch mid-session.
Learning flow

From concept to verified competency

Every chapter follows the same sequence. No skipping steps.

1
Read the theory
Each section explains the concept with production context, code examples, and operational callouts.
2
Guided exercise
Follow step-by-step instructions with per-step solutions revealed on demand.
3
Launch your lab
Your isolated environment starts in under 60 seconds. Dataset pre-loaded. Ready to use.
4
Solve the challenge
A real scenario. Interact directly with the database. No guidance unless you request a hint.
5
Get graded
Submit your work. The grader inspects actual database state. Immediate result.
