Subject: Re: Does Ruby has any default database with it?

I think the best course for a new project is to start simple, go with
sqlite, if you find you need more performance or some particular
feature, bump up to postgresql. mysql is pretty common, but there are
concerns about its future under oracle. That said, there's no shortage
of opinions everywhere.

The Sequel gem is probably a good place to start, since it sounds like
you're well of in SQL programming:

Even with that, it can take a bit to understand the Ruby that goes
around it, so I'd suggest experimenting a bit, do some prototypes to
figure out what you need, throw them away and then design, write your
tests, then write your app code.
