Hi all: AFAIK, it is possible in a bunch of database software to query multiple DBs through joining. I have a Foxpro background (so most of what I say is therefore, b.s.) but you can define your query tables using this notation:
database.table Which allows you to query multiple DBs. You should be able to do this (using joins) in MySQL. However, I don't know how off the top of my head. That might be more of a MySQL-list-geek type of question.
