Hi,
I was lucky enough to learn ruby a bit before starting to learn rails.
That has helped quite a bit.
Unfortunately, my knowledge of SQL and databases in general started from
zero when approaching rails, and I find that trying to “get” database
stuff from the context of rails books and documentation is holding me
back.
Can anyone recommend a free online pdf or website that will teach me the
basics of relational databases and their terminology? Things like joins
and primary keys and proper data organization in tables etc.? Something
that solves the same problem for SQL virgins that “Ruby for Rails”
solves for folks who come to rails without any previous Ruby experience?
thanks,
jp
