Data analysis expressions (DAX) is the formula language of Power BI.
Learning the DAX language is key to empower Power BI users so they can
take advantage of these new Business Intelligence (BI) capabilities.
This volume clearly explains the concepts of DAX while at the same time
offering hands-on practice to engage the reader and help new knowledge
stick. This third edition has been updated for the new Power BI Ribbon
interface while still providing a bridge for readers wanting to learn
DAX in the Power BI, Power Pivot, or Excel.
