Mondrian is used for:

  • High performance, interactive analysis of large or small volumes of information
  • Dimensional exploration of data, for example analyzing sales by product line, by region, by time period
  • Parsing the MDX language into Structured Query Language (SQL) to retrieve answers to dimensional queries
  • High-speed queries through the use of aggregate tables in the RDBMS
  • Advanced calculations using the calculation expressions of the MDX language
