What is wrong with dictionary of dictionaries (NSDictionary/
NSMutableDictionary)? Unless you are planing to have really huge
number of books in your system, you should be fine. If you are
planing to store huge number of books, than you should look into Core
Data.

Dear All,
I was wondering what is the best approach to the following scenario:
I have a library application where I intend to store my books under
some
categories. Now I have a NSOutlineView to do that interface wise.
But how
should I store the categories? The problem is that user should be
allowed to
create as many categories and subcategories as they want, much like
the
behavior of folders tree. Also I need to associate each book with a
category, and users should have freedom to change the book's
category, just
like the case of moving the file from one folder to another.
Is there something in obj-C that I could use here or do I need to
create my
own data structure to support this scenario?
Thanks a lot.
Regards
David
