Database setup of bridge/integration between scripts

Question

If I'm using an integration/bridge script for a cms and forums, more specifically drupal or mediawiki and vbulletin, how should I set up the database?

Should I have one database named "mysite" and place both cms and forum tables into the same database? So have all drupal tables with "drupal_" prefix and all tables with "vb_" prefix in the same database.

Or should I have two databases, one for the main site and one for the forums, and I wouldn't need table prefixes in that case.

What are the advantages/disadvantages of each method? Is one way less resource intensive? And is one way just downright better?

Thanks.

I'd say do separate databases if you can. The only reason to put two products in the same database is if you can only have one from your hosting provider.
