Prerequisite for the course:
Power Query and Data Modeling
DAX (Data Analysis Expressions) is a formula and query language used in Power BI to create calculated columns, measures, and custom tables. Knowing how to use DAX will take your Power BI analysis skills to the next level.
In this course, we will show you how to create custom functions, which will help you build sophisticated business reports in Power BI. DAX is easy to learn, especially if you have used Microsoft Excel in the past, as it includes some of the same functions. However, DAX also contains several functions that make the work with relational data easier.
