I have a fact table which has six field now and I have created non clustered index on all fields.
It will also have more fields later with millions of records .
Pretty small table, in other words.
Please suggest me my indexing will help on this table or should I create index in some other way to optimise performance .
Yes, indexes will probably help, you'd design indexes same way you would for other smallish tables or large tables: based on the queries which run against them.
