Multidimensional Expressions (MDX)

Multidimensional Expressions was originally developed by Microsoft. It emerged in the late 1990s and is often used in the context of online analytical processing (OLAP) systems.

Multidimensional Expressions helps to manage data that has more than two dimensions where traditional SQL query language may not fit the bill. Think about all of the modeling that goes on with complex data sets today. Multidimensional expressions is one tool or resource that developers and engineers can use to direct this more sophisticated data through more sophisticated data handling systems.
