What type of expressions does DAX use for data calculations?

DAX, or Data Analysis Expressions, is a specialized formula language designed specifically for use in data modeling and analytical calculations within tools like Power BI, SQL Server Analysis Services, and Excel Power Pivot. By utilizing DAX, users can create powerful and complex calculations that enable deeper insights into their data set.

DAX focuses on working with relational data and offers functions specifically tailored for data manipulation, aggregation, and complex queries. It includes a wide range of functions, such as time intelligence functions, statistical functions, and mathematical operations, which are pivotal in creating insightful data visualizations and analyses.

The other options refer to different programming and markup languages that do not relate to DAX or its function in data analysis. JavaScript is commonly used for web development, HTML is a markup language for structuring web content, and Visual Basic is an object-oriented programming language known for its use in application development. None of these languages provide the specialized data analysis capabilities present in DAX.
