Re: Re: entities Vs value object

Entities vary by id and have a life cycle.
Value objects vary by data and do not.

Its quite simple and most objects can be either. Take a printed note of
money. I can be in a context where I go to the store, do I care which $10
note I take out of my pocket? (value object). The central bank however
cares about the movement of an individual note (identified by its id)


Please do not take the answer before mine to have anything at all to do
with DDD definitions and will likely confuse the hell out of you. Value
objects have nothing to do with being exchanged between applications.
