Teaching relational databases the wrong way

Currently I'm experiencing how a teacher can teach relational databases the wrong way. It's virtually impossible to explain how to bring a table into the first normal form without explaining what a primary key and a foreign key is. So nobody understood what it's actually about (except for those who knew what relational databases are all about), no, it confuses them more than it actually helps.


Her style of drawing entity relationship diagrams is also really strange, just like Access does it. That really sucks IMHO. I wish she'd use the style that I learned a few years ago at HTL Leonding. She also praises Visio to be the best tool around for drawing ERDs. I simply cannot agree. Unfortunately OmniGraffle only supports this strange "crow foot" notation for relations, which I don't like, either.
