DAX

DAX (Data Analysis Expressions) is a formula language used in Microsoft's Power BI, Power Pivot, and Analysis Services for creating custom calculations and data analysis. It enables users to define measures, calculated columns, and tables that enhance data insights, similar to formulas in Excel but designed for complex, large-scale data models. DAX helps transform raw data into meaningful information, supporting advanced reporting and decision-making with efficient, reusable expressions that adapt dynamically to data changes.
