I want to get the many data for a given relationship. Lets say I have a Department and I want to get all its Employees. Department has a relationship called employees. Is this what I do?
id result = [aDepertment valueForKey:@"employees"];
What do I get back? Is it an array, a set, or some other kind of container?
Should I be using mutableArrayValueForKey from NSKeyValueCoding protocal?
I have been reading the Core Data docs and all the examples show situations that return only one object.
