Hi, im trying to implement a domain driven model and i am having problems identifying "entity and value objects",i don't understand very well the concept of "identity", and life cycle.
I have an objecto University that is organized in departments, and each department can have others department (sub-department).
Clearly the university is an "entity object", but departmens ...,? both are identified by its names, but 2 departments with the same name can't exists in the same university, so the identity of department is attached to the university's identity. Is department an entity object? or a value object? what is the identity?
Anyone could help me...
