Hi,
thanks for the reply.
Is it also possible to filter the entries of an NSDictionary like in SQL?
for example I have a key "type" and different entries.
Is it possible to get an Array of all elements where "type" is equal to "website" (or something like that)?

I would start with an NSArray of NSDictionaries, and then if it makes the code cleaner replace the NSDictionaries with custom objects containing the fields you're interested in and whatever other methods logically belong there.

Take a look at the NSArrayController and bindings API documentation--- if bindings do what you need, they're really quick and convenient.
