Re: Materialized view selection.

Depends mostly on your users needs. If most of the time your users would want monthly sum of measures, you give them a materialized view for that.
You can also use the summary advisor feature of oracle (dbms_olap) to find out which mviews oracle thinks is needed based on usage.
