Mondrian is an Online Analytical Processing (OLAP) server written in Java. It enables you to interactively analyze very large datasets stored in SQL databases without writing SQL.

It executes queries written in the MDX language, reading data from a relational database (RDBMS), and presents the results in a multidimensional format via a Java API.
