Presentation Title:
Understanding Data Analysis Expressions (DAX) Foundations - Francesco Bergamaschi

Description:
DAX (Data Analysis Expressions) is a simple language of Power BI calculations (but not easy at all). Its five foundations are essential to understand in order to avoid confusion when they inevitably interact in your measures, calculated columns, or calculated tables.

In this session, we’ll explain the five DAX foundations step by step:
🔹 Filter Context
🔹 Row Context
🔹 Context Transition
🔹 Iterations
🔹 Expanded Tables

Each foundation will be illustrated with clear examples, first individually and then in combination, showing how they work together. Examples increase in complexity gradually, giving you a structured path to fully understand how DAX behaves.

What you’ll gain
🔹 Deep understanding of the five DAX foundations
🔹 Ability to anticipate and troubleshoot interactions in your calculations
🔹 Practical skills to write accurate measures, calculated columns, and tables
🔹 Confidence to handle more complex DAX scenarios

This session is ideal for anyone working with Power BI who wants to better understand how DAX works. Whether you create measures, calculated columns, or calculated tables, understanding these five foundations will help you write accurate and efficient calculations.
