Re: Responsibilities of ApplicationServices versus DomainServices

It's not a heuristic but a clear-cut rule: objects whose life-cylce
coincides with the life-cycle of the process that creates them are said to
be transient. Objects whose life-cycle is independent of the life-cycle of
the process that creates them are said to be persistent. The distinction is
a business one: transient objects are not shared across processes,
persistent ones are.
