Don: As someone who is learning WO I can honeslty say I would have looked at your tutorials sooner if I'd known about them. They're a great addition since the best intro material I've seen so far is Apple's documentation (I've read all of it and it is still really useful and conceptual), and you help bridge the gap between thier use of deprecated tools and WOLips. (When I was done with that Chuck's book became very useful too.)
I've a question though. In your EoModelerBasics show, you made a to-one relationship from a Person entity to a Cadency entity (a title, like Jr or Sr). I get it. You also made the inverse to-many relationship from Cadency to Person. I don't get that. If I assume that I will never traverse an inverse relationship (I will never want to know what people have a Jr in their signature), do I have to model the inverse relationship? I've been skipping that. One more question while I'm at it. What's the best way to model a linked list? I've thought of putting list items in a table with an inbred relationship that links to other list items. My concern is that to retrieve the list at once I'd have to have many trips to the database, because in a single fault I will only know the root item in the list, and after each succesive fetch will only have a reference to one more item. I don't know much about stored procedures; can one be written to fetch the entire list?

This is something that I use my spare time to support. Based on my review of hits to the tutorials, they are rarely accessed. If they were used more, I would create more of them. The tutorials I made are available at: http://web.me.com/pccdonl/tutorials/WoLipsInstall.htm as is the installer. (I havent updated the installer in a couple of months) Don
