Is indexing possible in snapshot Database (SQL Server 2005)

I am planning on using a Snapshot Database for a read-only database that is being used for reporting, using the SNAPSHOT OF command.

Is it possible to create index on this snapshot database, to make the reports more efficient?

Thanks

snapshots actually fetches the data from the original database, so if you create the index on the original db your queries will be able to use this

so the indexes carry over to the snapshot database?

But can we create any new index on the snapshot database?

I urge you to read the article I posted in your other thread:
Capture the reporting benefits of database snapshots in SQL Server 2005
http://articles.techrepublic.com.com/5100-10878_11-6146916.html

The key part is in the first sentence:
"Database snapshots allow you to create read-only databases for reporting and can also be useful in your data recovery efforts in the event of a disaster."
I am not sure how much clearer that has to be.

acperkins,
very sorry.. that was a big oversight on my part.. Thanks for your patience and clarrifying that in simplest terms.

I had read that article when you mentioned it first, and observed the heart of what this feature is all about.

You have convinced me of snapshot databases, and i have been playing with it some, and i was thinking hard before moving on, this topic being new to me, if i am missing any other details, and that is where this oversight came into the picture..

aneeshattingal,
Thanks for mentioning the moving of the indexes into the destination Snapshot database. That makes perfect sense.

in my test, the Snapshot database queries, some complex, were much faster than in the source database. What feature of snapshot database would you attribute this to?
