DDD Infrastructure services

Question

I am learning DDD and I am a little bit lost in Infrastructure layer.

As I understand, \"all good DDD applications\" should have 4 layers: Presentation, Application, Dom

Answer 1

An unfortunate thing about DDD is the word 'Service'. What it should be is 'Domain Service'. Think of the Domain as entities and value objects, while Services are a way of dealing with actions, operations and activities.

As for the Repositories, they are just a facade that should behave like a collection to your domain. If you are using an ORM or writing your own, this is what all your domain objects should be going through in order to achieve persistence instead of those services directly.
