SSAS Interview Question: Measure vs. Calculated Measure

In SQL Server Analysis Services (SSAS), a measure is a numeric value that represents aggregated data based on a specific column or expression. It is a fundamental part of a cube and is used for analysis and reporting.

On the other hand, a calculated measure in SSAS is a user-defined measure that is created using MDX (Multidimensional Expressions). It allows users to define custom calculations based on existing measures, dimensions, and other data points in the cube.

While a measure is typically derived from the underlying data source and is pre-defined, a calculated measure provides additional flexibility and allows for more complex calculations to be performed within the cube.

Understanding the difference between a measure and a calculated measure in SSAS is essential for working with multidimensional data models and creating meaningful and insightful reports.
