My Full Power BI Data Modeling Course is Here (100% Free)

Over 5 hours, from the star schema all the way to a full hands-on project. All on YouTube, all free.

Hey friends, Happy Tuesday!

I have been waiting to type these words for a while, and today is the day:

🎉 The full Data Modeling course for Power BI is now LIVE and 100% free! 🎉

Over 5 hours, from the very first “what is a data model” all the way to a full hands-on project. All on YouTube.

To Be Honest With You

While I was building this course, I could not find anything like it on YouTube. The few paid courses that come close to this quality are charging around $500.

And I understand why. Data modeling is not something you can just read about and then teach. It only comes from working on real projects in real companies.

I could have easily put a price on it. But I still remember how it felt to want to learn something and not be able to pay hundreds of dollars for it. So just like my SQL, Python and Power BI courses, this one is yours, for free.

This is the most important chapter in the whole Power BI. I got invited many times to save Power BI projects that were failing and giving wrong numbers, and almost every time it was the same mistake. They skipped the data modeling.

And if you know me, you know I teach visually. Every concept is drawn by hand so the ideas actually stick.

📖 What’s Inside

• Why Data Modeling matters

• Tables and Schemas: facts, dimensions, star, snowflake, galaxy

• Relationships: cardinality, filter direction, active vs inactive

• Special Dimensions: junk and role-playing

• Fact Tables: the grain, multiple facts, the bridge

• Row-Level Security (RLS)

• The Nightmare Project: a full hands-on rebuild, end to end

• Golden Rules recap

Two Tips From Me

1. Learn it well. Data modeling is one of the most asked topics in data interviews. Master this course and you can handle almost any modeling question they throw at you.

2. Do the final project. We take a messy 23-table model and rebuild it into a clean star schema, step by step, exactly like I do at real work. It is yours. Build it, and put it in your portfolio. If you share your success on LinkedIn, a little credit would be awesome. :

That is it for today. Go build something clean.
