Core Data

I'm working through a tutorial on cocoadevcentral about Core Data.  The concepts of it are actually the hardest part.  I don't fully understand what is going on.  However, it is simple to develop with it, as is often true with these Apple technologies.  It is similar to working with Interface Builder in that it is all graphical and no actual code has to be written to use Core Data.  This makes it easy to follow along and know what I'm doing.  Unfortunately, it really is so complex that I'm doing much more with Core Data than I should be able to with my limited knowledge.  So there are a lot of things that I don't quite understand but hopefully they will become clearer as I work with it more.
