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 -- Posted via http://www.ruby-forum.com/.
