DAX easily handles and compares various data types, much like Microsoft Excel. However, the underlying computation engine is based on SQL Server Analysis Services and provides additional advanced features of a relational data store, including richer support for date and time types.
This beginner’s guide gives you foundational skills to confidently start using DAX expressions. With consistent practice, you’ll soon master Power BI’s powerful analytical capabilities.
If the operators have equal precedence value, they are ordered from left to right. For example: If an expression contains both a sum and a comparison, the sum is executed before the comparison.
It provides a comprehensive overview of DAX concepts, illustrates their application through examples and screenshots and highlights optimization techniques to maximize performance. With this knowledge, readers can confidently explore and harness the capabilities of DAX in their Power BI projects.
Below is a comprehensive list of 50 useful DAX functions, categorized by their primary use case, with brief descriptions and examples to help you leverage them effectively in Power BI.
Data Analysis Expressions (DAX) is a library of functions and operators that can be combined to build formulas and expressions in Power BI, Analysis Services, and Power Pivot in Excel data models.
