PowerBI DAX - Fundamentals for Beginners

Power BI Weekly: Session 12
Introduction to DAX (Part 1) | Power BI DAX Fundamentals for Beginners

Week 5 begins.

In this session, we introduced DAX (Data Analysis Expressions) — the formula language that powers calculations in Power BI.

After learning data cleaning, transformation, and visualization, this is the next step: creating dynamic calculations.

📚 WHAT YOU’LL LEARN:

📊 DAX Fundamentals
- What DAX is and how it works
- Why DAX is essential for data analysis

🔍 Three DAX Objects
- Measures (dynamic calculations)
- Calculated Columns (row-by-row logic)
- Calculated Tables (new tables)

🧮 Basic Functions
- SUM
- AVERAGE
- COUNT / COUNTROWS / DISTINCTCOUNT
- MIN and MAX

⚙️ Creating Measures
- Step-by-step creation
- Naming and formatting properly

🔄 Implicit vs Explicit Measures
- When to use each
- Why explicit measures are best for real projects

🎯 Best Practices
- Writing clean DAX
- Avoiding common mistakes
- Structuring reusable calculations

💡 Key Insight:
Measures calculate at query time and respond to filters.
Calculated columns are static and stored in the model.

This is where Power BI moves from visualization to real analytical power.
