I had the pleasure recently of being on an episode of the Mac Developer’s Roundtable with Kevin Hoctor, Aaron Hillegas and Steve “Scotty” Scott. In this latest episode, Scotty introduced the topic of data, how to store it, access it, etc. To kick it off, Aaron delivered a fantastic history of Core Data or as it was originally called, Enterprise Objects.
I highly recommend this episode to anyone who is interested in Core Data and Cocoa in general.
You can get the episode from MacDevNet.com.
