Re: Future of bbPress
The reason why bbPress needs Oracle support is because if you are trying to integrate it into any existing site run by an actual company and not a hobbyist, there’s a good chance their user database is in Oracle (or MS SQL Server).
PHP supports Oracle so why should bbPress be tied to just MySQL. I don’t think it is really using much (if any) MySQL specific code.
This is one of the main selling points of PHPBB – it supports FireBird, MySQL, MS SQL Server, Oracle, PostgreSQL and SQLite.
