Domain driven design repository implementation in infrastructure layer

Question

I got a question on dependencies of DDD layered architecture. If the Repository implementation is in the infrastructure layer, that means that infrastructure layer has a depende

Answer 1

Yes in your case. And I have the same question :)

Here is my explanation:

It seems that Infrastructure layer is a special one in eric evans' arichitecture diagram. It implements Interfaces, Application, Domain.

This one is kind of farfetched.....

But on the other hander, you could split infrastructure into seperate adapter module since the infrastructure components are typically composed of adapters, translators and facades.

For example,

1)Domain may have a dependence on mailing if you inject a MailManager to a DomainService. 2)Persistence have a dependence on Domain (Repository case).

But if you seperate mailing and persistence into two modules, they have no depedence on each other. I think this may alleviate the problem.

After all, layering is a method to decouple components not a purpose.

Last but not least, I expect more convincible answers :)
