Core Data and NSOperation

Hello everyone, I'm a bit of a Core Data newbie, so any thoughts on 
this would be much appreciated...

I have some objects, where each performs calculations, so I've 
subclassed NSOperation so that I can configure their dependencies and 
execute them on an NSOperationQueue.

I want to store the objects using Core Data, but have come up with a 
possible problem. I've not used Core Data before, so I may have 
understood this incorrectly, but the entities must be subclasses of 
NSManagedObject, which NSOperation is not. So... how can I use Core 
Data to manage the fetching and storing of the data, but NSOperation 
to handle the computation?

I've thought that I could maybe use my NSOperation based class as a 
delegate of some NSManagedObject based class, which the Core Data 
entity is based on. Is that possible? Or is there a better way? Does 
Objective-C support multiple inheritance... I don't think it does....

Thanks in advance!

Cheers
Dan
