A seprate database for PHPBB or merge the tables with the site?

I have a databse for the main website that will contain ~15 tables.
Are there advantages/disadvantages to merging the phpBB tables with the one from the site or seprating the tables sets in 2 different databases?

What is generally the best way to go?

I would create the 15 tables in the phpBB database to keep everything together, makes it easier to maintain. I can't see any advantage to create a new database.

Ok, thanks for your input Len.

You should split data across databases when the data is completely irrelevant. When your data is for your site, as well as a board for your site, then there is no problem combining into the one database.

Just my two cents on when/when not to split data over databases.

In short, a ME TOO!
