Having worked doing BI work for a bit during a semester off it seemed like there is so much money to be made in the 'BI for the masses' space. Interesting to see some competition for SAP , MS and Oracle popping up, I'm rooting for them.
Pentaho and Tableau are nice. Jaspersoft not so much but they have the best reporting design software. All of them are a refreshing break from Oracle/Microsoft
I just found Pentaho few days ago and we plan to use it for BI on our huge mongo db data set. Any hints you could provide?
