Introduction to Numeric Calculations in DAX
DAX (Dynamic Analysis Expressions) is a formula language to enrich imported data with calculated columns, calculated tables and measures in Power BI, Excel and Analysis Services. While the syntax of the language is derived from Excel’s formula language and easy to learn, some of the functions are hiding a complex semantic.
This talk starts on a zero DAX knowledge level but will introduce advanced concepts. We will concentrate solely on numeric calculations. You will learn the difference between calculated columns and measures and between row context and filter context. We will discuss how CALCULATE operates.
Markus will gently walk you through different examples of increasing complexity which will pick your brain – don’t forget to bring your favorite hot beverage to stay focused during this 60min!
