Ive tried to gather information on as to how core data works, but can someone give me a clear explanation of all the stuff required...For instance NSDataContext, Fetchcontroller, NSDataModel, Presistent...

Perhaps all the steps involved to get a data...Now I'm also unclear about an SQLite file, like how do we load the data into the core data , once we have created our entities etc..

Thanks
