FAQ

Common questions.

  • Do I need SQL experience?

    No. We start from your first SELECT statement. If you have never written SQL before, this is the right starting point.

  • What database do I need?

    PostgreSQL via Docker. The workshop includes Docker Compose setup so you are running queries within minutes.

  • Is this just theory?

    No. Every lesson runs against a real 100k+ order dataset from a Brazilian e-commerce platform. You write real queries, not textbook examples.

  • How long does it take?

    About 16 hours of hands-on work. Go at your own pace, the content is always available.
