Hey Friends, this is the start of DAX, fully animated and this going to be awesome! I would love to see your support by pushing on the channel by Subs, Hype, Like, and comment to reach more nice people like you.
If you take one thing from this video, take the golden rule: push your preparations as far upstream as possible and leave Power BI for the visuals and the measures. It going to save you from so many slow reports.

I don’t usually leave comments on YouTube, but I’m making an exception this time. I’ve taken courses on Power BI and followed lots of channels and tutorials, and I have to say that your detailed, clear and to-the-point content has really captivated me. You explain things and concepts that other channels overlook, yet which are constantly repeated from one channel to another. Well done on your work, and thank you for sharing your knowledge.
