"Everyone says “learn DAX.” But nobody explains why. Here’s the truth: Without DAX, Power BI is just pretty visuals. With DAX, it becomes a decision-making engine. Start with these 7 functions: 1. SUM() → totals 2. AVERAGE() → mean values 3. COUNTROWS() → row count 4. DISTINCTCOUNT() → unique items 5. CALCULATE() → context switcher 6. FILTER() → slice your data 7. RELATED() → connect tables Master them. Then layer complexity slowly. Because the analysts who know DAX… are the ones driving real impact. SEE ALSO: If you would like to get to the AI (and AI like) Capabilities available within PowerBI, You can also refer to this book : AI within PowerBI.
