Saiku allows business users to explore complex data sources, using a familiar drag and drop interface and easy to understand business terminology, all within a browser. Select the data you are interested in, look at it from different perspectives, drill into the detail. Once you have your answer, save your results, share them with other users, export them to Excel or PDF, all straight from your browser.
Saiku offers a community edition and an enterprise edition with many more features. Saiku offers also a plugin for the Pentaho suite (available on the Pentaho marketplace) and is very useful for multidimensional analysis and OLAP reporting.
