Domain Elements

I'm currently reading Functional and Reactive Domain Modeling by Debasish Ghosh and TIL some characteristics of the various domain elements:

Entity: Has an identity; Passes through multiple states in the lifecycle; Usually has a definite lifecycle in the business

Value object: Semantically immutable; Can be freely shared across entities

Service: More macro level abstraction than entity or value object; Involves multiple entities and value objects; Usually models a use case of the business
