The Data Analysis Expressions (DAX) language is a formula language that allows users to define custom calculations in calculated columns and measures. DAX includes some of the functions that are used in Excel formulas, and additional functions that are designed to work with relational data and perform dynamic aggregation.
You can add references to custom code embedded in a report or to custom assemblies that you build and deploy to the report client and to the report server. Use embedded code for custom constants, complex functions or functions that are used multiple times in a single report. Use custom code assemblies to maintain code in a single place and share it across multiple reports.
