Hello, im curious i just picked up a book, for it, Is there any database for it already like mysql? what is the limits to it, from what i have read from it. It doesnt have any database to make user systems in.
Basically it seems like it just puts out html in .rhtml format its confusing to me.

Can someone explain this to me if there is a database, or no. What ror can do, like can you build a user system with ror alone. and what database do i use to do this.
Thanks!
