This Introduction to DAX for Power BI presents Data Analysis Expressions (DAX) in Power BI from an intermediate to an advanced level. The journey starts with an introductory discussion about DAX, the syntax of DAX statements, and how to write structured DAX in the DAX editor. You also get an introduction to DAX Studio, a third-party tool that can be used to write DAX. You can decide if you want to use DAX Studio for the course exercises.
We will discuss many of the functions in DAX and how they could be used in a Power BI Project including explaining the use of iterator functions vs standard statistical functions. There are discussions explaining Calculated Columns, Tables, and Measures discussing the differences. There is also an explanation about Quick Measures and how we can utilize those. We will explain DAX Context and where those contexts apply. There are separate discussions for the CALCULATE function, the usage of a Data Model and incorporating a Date Dimension, and also using Time Intelligence Functions. We will conclude with a discussion around utilizing DAX with Row Level Security.

DAX is an acronym for Data Analysis Expressions. DAX is a functional programming language that consists of a collection of functions, operators, and constants that can be used in a formula, or expression, to calculate and return one or more values. DAX enables you to extract information from the data already in your model.
DAX consists of over 200 functions and these functions are split into categories. It is the combination of these functions that enables you to return insightful information from your data model. One example is the use of the Time Intelligence functions that enable you to calculate period comparisons quickly and effortlessly such as Previous Month, Previous Quarter, or Previous Year.
No, all software and licenses are supplied as part of the Training Course which also means you are not affecting your organization's Power BI Infrastructure. All Reports will be created in the Training System which is an implementation of a live system. The course virtual machine is available to you for a period after the course has finished.
