Answer Posted / prakash m

A convenient grouping of random flags and attributes to get
them out of the fact table
Retain only useful fields
Remove fields that make no sense at all
Remove fields that are inconsistently filled
Remove fields that are of operational interest only
Design similar to demographics; maximum unique
combinations, assign integer key, plug into fact
Create new combination (insert new dimension record) at ETL
run-time
E.g. Yes/No Flags in old retail transaction data
