In this video, I share three golden rules of data modeling that I personally follow in Power BI.

• When to merge one-to-one tables
• How to reduce the height and width of fact tables
• Why thinking in star schema often removes the need for complex DAX

If DAX feels hard, chances are the model needs fixing first.
Let me know which rule you use the most.
