In my little web project that's about to be started, I'm condsidering two different pieces of software, being OsCommerce, and phpBB2. Both of these are PHP based softawres, and both of these require a MySQL database. At the moment, I'm getting ready to start putting this project together. I've installed Apache, and I'm downloading PHP 4 at this very moment, which I'm about to install onto Apache The problem is twofold. I know very little about MySQL, and so I'm wondering if there's anything I need to do to enable it on my apache server? The other issue, is that the host I'm thinking of using offers only 1 MySQL database for the price plan I would like to use. I was wondering then, whether it would generally be possible to set up OScommerce, and then use the same Db to install phpBB2, or vice versa. If it is, in time I may even be able to link the two by user-account (ie, one single sign in - once I know a little more). Alternatvely, is it the case that this is not possible, and I would have to go with a higher hosting plan to use a second database, and if so, would there be any way of linking the two pieces of software (not specifically, but purely in theory) to create a single sign-in scenario?
