  2. DAX (Data Analysis Expressions): DAX is a formula language used to create custom calculations and expressions in SQL Analysis Services. It provides functions and operators to manipulate data and perform calculations.

Querying Data using MDX

  1. Write MDX queries to retrieve data from your multidimensional model.

  2. Specify the dimensions, hierarchies, and measures you want to include in your query.

  3. Apply filters, slicers, and sorting to refine your query results.

  4. Use MDX functions to perform calculations, aggregations, and data transformations.

Querying Data using DAX

  1. Construct DAX queries to retrieve data from your tabular model.

  2. Define the tables, columns, and measures you want to include in your query.

  3. Apply filters, sorting, and grouping to refine your query results.

  4. Utilize DAX functions to perform calculations, create calculated columns, and generate new measures.
