How can I create a database in SalesForce. I don't care about the language, I just want to be able to make a large capacity database that I can interact with via SalesForce, Apex, or VisualForce. Currently my solution seems to run out of memory. I have read in-to MySQL, PHP, etc - however I can't find a way that SalesForce can interact with these. I have also heard of Cloud Database or Force.com, however, I again, haven't been able to see examples or anything that would actually help me beyond an advert. Can anyone lend a hand?
