DAX Introduction

Today I started the "Calculated Fields with DAX" section of the Power BI course I'm working on through Maven Analytics.

I have seen DAX referenced in a few places, but this is my first actual foray into knowing what it is and how to use it.

My understanding so far is that DAX is the language that really drives the front-end of Power BI. It allows you to create new measures, calculated columns, and perform functions akin to those found in Excel. Using DAX to create an explicit measure for an aggregated column means that you can use the aggregation in other areas of the report, unlike the manual options.

I'm only 6 out of 44 steps into this section, so that's all I have for now.
