Leina Future Data & AI Hub – Weekly Tip (Inspired by Microsoft Learn)

💡 100% true — data modeling is the backbone of Power BI.

You can build the most beautiful visuals, but without a solid model, insights will always be misleading.

✔ One-to-many relationships ensure accurate aggregations and prevent double counting.
✔ Star schema keeps models simple, performant, and scalable — fact tables at the center, dimensions around them.
✔ Filter direction controls context flow; using single direction by default avoids ambiguity and performance issues.

📊 A strong model means:

• Cleaner DAX
• Faster reports
• Fewer bugs
• Trusted business decisions

👉 Rule of thumb:

Fix the model first. DAX and visuals will follow naturally.

This mindset separates Power BI developers from Power BI professionals.
