More on iOS Core Data

I am really enjoying the chapters on core data application development. It appears to be a bit easier to understand than that of the other introductory chapters of iOS development. Moreover, this is something that is applicable to what I do, which is database development. Yes, it is very early, but it is very promising. It discusses how to set up entities, attributes and relationships. What more do I need? Well, anyway, I am interested on learning about where the data are stored. I assume that as I read on this will become more apparent.

Unlike SQL databases, there are inverse relationships that have to be set up. I will have to read it again as I am used to a one -> many directional relationship without care about what comes back. This will be a new learning.

The chapter also introduced the @dyanamic construct which is what is used when you have properties declared in an .h file but you are not ready to synthesize in the .m implementation. I am not yet at the point where the properties will be invoked but my curiosity is piqued.
