I can't describe the whole thing, since there are parts I'm not sure about, but from I can tell...


The rectangles are your tables. Each ellipsoid is an attribute (column) of its respective table. Your diamonds are the relationships between the tables, and each of these relationships is denoted as a 1-to-many or many-to-many relationship. If I'm not mistaken, the "U" symbols denote one table is a subset of another, where the superset is the one being "stuck by the fork."

Outside of that, what are you having trouble with?
