what's the advantage using Core Data Framework?
Core Data is a really useful technology but it’s not the only way to persist your data. There are lots of other options (user defaults, JSON, property lists, keyed archives, ‘raw’ SQLite, custom file formats, and so on) and the best option very much depends on the nature of your data. This includes things like:
How much data you’re dealing with, both in terms of number of items and size of those items?
Is there a complex internal structure?
How you access that data?
Core Data shines where there’s a lot of data with complex internal structure and you don’t want to load it all into memory at once. From your earlier posts it seems like Core Data isn’t a great fit for your requirements, but rather you’d be better off using a keyed archive for the most of your data and separate on-disk files for your images.
