The best way to learn SQLite is to learn SQLite and ignore Core Data
completely. While Core Data technically uses SQLite, it does
undocumented voodoo with SQLite, which is subject to change with any
Apple whim at any particular moment (except on thursdays). For all
intents and purposes, Core Data + SQLite should basically be
considered a proprietary format.
If you want to learn SQLite, get a book or two on it, or go to their
website. If you want a Cocoa framework that does a bit of what Core
Data does, check out QuickLite http://www.webbotech.com/
You might also want to pick up a copy of Martin Fowler's Patterns Of
Enterprise Application Architecture if you'd like to understand more
about how to store and retrieve objects using relational databases http://tinyurl.com/4rvlaj

I just finished my first simple Core Data Document Based
Application. Four entities with multiple relationships. Now I want
to recreate the same thing using just SQLite. I don't know SQLite,
and I know very little Unix. I had read it was possible to study
SQLite using Core Data, but I am making no progress. The closest I
could get to opening my core data sqlite document with sqlite3 was
to try mycoredatadoc > sqlite3 in the Terminal, but permission was
denied.
Any suggestions?
