I know that it's possible to have CiviCRM shared across multisite Wordpress, and for a single database to operate in a way that keeps different site's data separately.
I'd like to do something superficially simpler, but which I can't find any mention of anywhere.
I'd like two sites in a multisite install to use the same CiviCRM codebase, but completely separate databases. To my mind, I just don't want to the two website's data mixed together, even if they are kept separate from a user perspective.
Could this be as simple as a PHP switch in the config file which says (psuedocode) ...?
If Website A: Use Database A Else: Use Database B
But I realise that with logs and Smarty cache files it might be more complicated than that ...
