Note: I am building a startup. I am currently using mysql. I am pretty much stuck. Others recommend other free databases like mongodb. I am seriously considering paid one IF and only IF it gets better result.
I haven't made up my mind. This is an honest question. Yes I understand there have to be some edges. Otherwise why would anyone pay for something they can get for free. But what?
What do we get more with paid databases that you've tried?
Quora uses mysql Foursquare uses mongodb Facebook uses mysql
And those are the some of the biggest out there is when it comes to database.
I mean if people can build something SO BIG with FREE databases.
Why do anyone need paid dbms?
Not to mention hundreds of other alternatives that I never heard about. If I am using them I will be using unproven product.
