re: large database

In my opinion one database is better solution, but of course you should design it well. The main problems with databases
1.your application should make more than one connection, and it probably will take some time,
2.what if you want to merge data from different databases, will you use dblink module, or you application will do it for you (i think db should do it for you)

This is my opinion.
