For anyone who lands on this thread, I'd like to recommend a couple of links that point to some youtube videos.

Database Concepts etc from Dr. Daniel Soper starts here


Programming in MSAccess by Steve Bishop starts here

For information on relational theory, database management etc, any youtube video by Dr. Jennifer Widom is very much worth reviewing. Here's one of several.

The thing about these videos is that you can pause, reverse and replay as necessary.

Good luck.
