I would start by reading an introduction book to WebObjects. Each one deals with this topic. In case you can't find one, start with Apple's documentation: http://developer.apple.com/documentation/DeveloperTools/WebObjects-date.html#/ /apple_ref/doc/uid/TP30000440-TP30000436-TP30000592

Although examples of the mechanics of how to create a relationship mostly refer to using WebObjects with Xcode which of course has been deprecated, the theory is the same.

You just need to apply the same ideas in Wolips. In Wolips, it's just as easy, right click on one of the tables involved in the relationship and select "New Relationship" select your fields and your done!

If you know nothing about relationships and Enterprise Objects though, again start with either Apple's Documentation or a book. My favorite beginner's book, Josh Marker's WebObjects 5, is out of print though you can find it at some libraries. Can't PeachPit print on demand? But there are others.

A good project to add to the WebObjects Wiki, a beginner's guide to WO. I'll get started on that right away! :)

(simple) examples of a two table join... I am assuming
that multiple table joins are similar to a two table
join (just more tables).

Any help starting (even pointers to web pages would be
appreciated).
