Yusuf,
Thank you for sharing this script. However I ran into to some problems where it returned way too many rows. The issue is that sys.indexes and sys.objects are database system objects but sys.dm_db_index_usage_stats and sys.dm_db_index_operational_stats cover the entire instance.
So you can have an object_id appear in multiple databases. I believe the query would need additional conditions in the WHERE clause. Something like:

AND IUS.database_id= DB_ID()
AND IOS.database_id= DB_ID()

That restricts the output to just the current database.

Thank you again for sharing the script.
