Data Analysis Expressions(DAX) are the collection of formulas, functions, operators, and constants that allows a user to create measures, dimensions, and custom tables. They return one or more values and are used to solve data analysis problems, creating a new relationship between different data variables.


DAX language is very useful as it allows the Data Analysts to perform advanced calculations and discover a hidden pattern in an unstructured dataset. The complete code of an expression is always a function or nested function with conditional statements, value references, formulas, loops, etc. It’s important to formulate as they are evaluated from the innermost to the outermost function of the expressions.


There are two primary data types in Power BI DAX functions:


Numeric: numeric data types include decimals, currency values, integers, etc.
Non-numeric: it consists of strings, binary objects, etc.
