What is DAX?
DAX stands for Data Analysis Expressions. It is a formula language and expression used in Microsoft Power BI, Power Pivot in Excel, and Analysis Services Tabular models. DAX is designed to work with data models and allows you to define custom calculations, create calculated columns, and build complex expressions for data analysis and manipulation.
DAX functions are similar to Excel functions but are optimized for working with large data sets and performing calculations in the context of data models. It includes a wide range of functions for mathematical and statistical operations, date and time calculations, text manipulation, logical operations, and more.
DAX is used to create measures, which are calculations performed on the data in the data model. Measures can aggregate data, calculate ratios, perform calculations based on specific conditions, and provide insights into the data. DAX also supports the creation of calculated columns, which are additional columns added to a table that contain calculated values based on a DAX expression.
