MDX stands for Multidimensional Expressions. It is a query language used to retrieve and manipulate data from multidimensional databases, particularly those using the Microsoft SQL Server Analysis Services (SSAS) platform. MDX is similar to SQL, but it is specifically designed for multidimensional data structures rather than relational databases. It allows users to define calculations, create calculated members, and retrieve data from various dimensions and measures within a multidimensional cube. MDX is commonly used in business intelligence and data analysis applications to perform complex calculations and analysis on data stored within a multidimensional database.
