Masterclass: DAX Advanced

DAX language was created specifically for the handling of data models, through the use of formulas and expressions. DAX is used in several Microsoft Products such as Microsoft Power BI, Microsoft Analysis Services and Microsoft Power Pivot for Excel. These products all share the same internal engine, called Tabular/Vertipaq (xVelocity before). With DAX we have the ability to include business logic in calculations in order to enrich our business intelligence models.
