What does MDX stand for in the context of data querying?

MDX stands for Multidimensional Expressions, which is a query language primarily used for querying and manipulating data in multidimensional databases, such as those used in online analytical processing (OLAP).

This language allows users to write complex queries that can retrieve data from multiple dimensions, enabling advanced data analysis and reporting capabilities. Its syntax and structure are designed to work specifically with multidimensional data models, making it an essential tool for business intelligence applications, where businesses analyze large volumes of data stored in multidimensional formats.

The focus of MDX on multidimensionality is crucial in scenarios where data is represented in different dimensions such as time, geography, or product categories, and it provides the functionality to aggregate and filter data effectively across these dimensions, enhancing decision-making processes based on the insights derived from the analysis.
