This 1 day course is an introduction to the DAX language to create your own calculated columns and measures.

DAX, short for Data Analysis eXpressions is the language behind Power BI. It’s a powerful language that’s evaluated through the filter context of the Power BI Data Model. This “Filter context” can cause new users to experience problems with DAX until they learn how it works.

Once mastered, creating effective DAX formulas will help you get the most out of your data. When you get the information you need, you can begin to solve real business problems that affect your bottom line. This is Business Intelligence, and DAX will help you get there.

To get the most out of this course

You should be a competent Microsoft Excel user. You don’t need any experience of using DAX but we recommend that you attend one of our 2-day Microsoft Power BI courses prior to taking this course.
