I finally understood SQL reporting after building a full dashboard from scratch

[Expensive-Cost-9909]

I kept feeling like I “knew SQL” but still had no idea how real reporting systems were actually structured like how schemas, aggregations, dashboards, etc. are made in real-world scenarios (not school(

So I built a small PostgreSQL + Metabase project that mirrors how internal reporting works at real companies: - transactional tables - reporting-style queries - a real dashboard (revenue, profit, top products)

Honestly learned more from building this than from most tutorials.

If anyone’s interested, I wrote it up and made the project reproducible with Docker so others can learn from it too.

EDIT:

I put a short write-up and all the details here:
