You didn't ask about materialized views, but they are one possible option when optimizing queries across dblinks.

Subject: View vs. Synonym (across DBLink)

While tuning a mammoth query, I noticed that one of the tables in the from clause is actually a view. It's defined as "select * from table_name_at_dblink". Is there any reason to believe I could improve performance by dropping the view and using a synonym instead?

Thanks,
Jon Knight
