Hello. I with friends design web-app on PHP, JavaScript and PostgreSQL. Now we needed create dashboard, but database very big and hasn't good optimization, because we want use OLAP system. In reseach I find testing ROLAP and MOLAP that show, then MOLAP very well executing query after preparing date. You can give me more information, how deploy MOLAP on Linux(ubuntu)? I was install Pentaho 7.0, was install Schema Workbench, and publish scheme in Pentaho, but Saiku Analyzer don't show scheme in list (list empty). How i can deploy true MOLAP system with prepair preprocessing and aggregating information. Sorry for bad English
