Pentaho Analysis Services: Mondrian Project

Mondrian is an OLAP server written in Java. It enables
you to interactively analyze very large datasets stored in SQL databases without writing SQL. |
Aggregation Designer 1.0 is now available
Pentaho Aggregation Designer is an easy-to-use utility for designing or automatically generating aggregate tables that improve performance when working with
larger datasets. It includes an intelligent adviser algorithm that analyzes your relational database schema and uses a sophisticated cost-benefit analysis to
