DAX stands for Data Analysis Expressions.
You may ask yourself, "Why is DAX important?"
Well, as a consultant and a developer I can tell you that DAX is where Power BI’s analytical power truly comes into play. Without DAX, you would miss out on the majority of Power BI’s potential as an analytical tool.
Consider Excel. If you didn’t know the DAX functions and how to use them, spreadsheets would lose their effectiveness. The same is true for Power BI reports and understanding the important role DAX plays in creating meaningful reports.
DAX Day is our way of helping you have a deeper knowledge of how to leverage DAX functions within Power BI. Once a week we'll be creating and posting helpful resources to accelerate your understanding of DAX and how you can use it. Make sure to download our DAX reference charts! They're great to have handy when building out reports, as they help you to see different categories of DAX functions as well as examples of how to use them properly.
On DAX Day(s) we'll also be providing blog posts and videos that will help you to go even further into the DAX arena.
