This comprehensive and authoritative guide will teach students the DAX language for business intelligence, data modeling, and analytics. Leading Microsoft BI consultants Marco Russo and Alberto Ferrari help students master everything from table functions through advanced code and model optimization. They'll learn exactly what happens under the hood when you run a DAX expression, how DAX behaves differently from other languages, and how to use this knowledge to write fast, robust code. If you want to leverage all of DAX's remarkable power and flexibility, this no-compromise "deep dive" is exactly what you need. u003cpu003e u003cbu003ePerform powerful data analysis with DAX for Microsoft SQL Server Analysis Services, Excel, and Power BIu003c/bu003e u003cbru003e u003culu003e u003cliu003eMaster core DAX concepts, including calculated columns, measures, and error handlingu003c/liu003e u003cliu003eUnderstand evaluation contexts and the CALCULATE and CALCULATETABLE functionsu003c/liu003e u003cliu003ePerform time-based calculations: YTD, MTD, previous year, working days, and moreu003c/liu003e u003cliu003eWork with expanded tables, complex functions, and elaborate DAX expressionsu003c/liu003e u003cliu003ePerform calculations over hierarchies, including parent/child hierarchiesu003c/liu003e u003cliu003eUse DAX to express diverse and unusual relationshipsu003c/liu003e u003cliu003eMeasure DAX query performance with SQL Server Profiler and DAX Studiou003c/liu003e u003c/ulu003e
