Schemas design, OLAP , ETL, and dashboards
Ive worked on OLAP cube design using star and snowflake schema in SQL Server 2012 earlier.. But now we wish to move on to an open source platform. So, please suggest is it possible to build a star schema using RapidMiner, then populate the tables with data using ETL, then apply OLAP operations such as slice and dice, drill down on the same and finally build a dashboard? If yes, please also suggest some possible links on how to do the same?
