Writing DAX Calculations for Power BI Semantic Models

Unlock the true potential of your Power BI data by writing custom formulas that deliver deep business insights. This text-based course guides you through the core concepts of Data Analysis Expressions (DAX) specifically for semantic models. You will progress from understanding basic syntax to writing complex calculations, enabling you to build robust, high-performance reporting models that answer critical business questions. In this course, you will learn to: 1) Understand foundational DAX syntax, data types, and operators. 2) Create calculated columns and measures to solve specific business problems. 3) Apply evaluation context, including row context and filter context, to write accurate formulas. 4) Utilize functions like CALCULATE to manipulate filter context dynamically. 5) Implement modern DAX best practices, including variables for readability and performance optimization. 6) Write time intelligence calculations to analyze trends over time. The training begins with essential data modeling terminology and basic formula structures, then moves into context transition and filter manipulation through clear written explanations and practical conceptual scenarios. Designed for beginners and aspiring data analysts, this course requires no prior DAX experience, though a basic familiarity with Power BI is helpful.
