Okay, laugh at me. Go ahead. It's my first true databasing attempt, using anything like this. So help me out. What's it mean? What's it do? Particularly in the Database Definition area.

Let's break up the words...
not is http://www.m-w.com/cgi-bin/dictionary?not
null is http://www.m-w.com/cgi-bin/dictionary?null
Therefore, with null being null, nada, nothing, etc. and NOT being a negative value. This means that the field must contain something, have value, be something, etc.
not null = have a value in it
null = does not have to a value in it
Hope this helps! I've found the dictionary to be quite helpful when learning new languages, like Perl...
