So, I'm taking an "Intro to Database Admin" course, and my professor is pretty disorganized and the textbook is so technical that I'm having a hard time understanding the concepts. I'm getting SQL OK, as far as running queries and so forth. In particular, I'm looking for resources on understanding Entity Relationship modeling and terminology. Any suggestions? I've done some Google searches, but there's so much out there and so far, none of it is any more simplified than my textbook.
