Wouldn't you have: class Car { Engine installedEngine; public installEngine(Engine engine) { this.installedEngine = engine; } } And a Service Layer would call:

Hi Dan, are you certain? Fowler defines Repository as follows: "Mediates between the domain and data mapping layers using a collection-like interface for

I don't think creating dependencies within your repositories is a good idea in general. It may be an indication that some of the domain related

Hi Çevik, ... Well, they refer to each other conceptually but they don't share the same time line. For instance you may register an Engine before registering

... The interface definition (ICustomerRepository, say) is part of the domain, but the implementation (CustomerRepositoryNHibernate) is part of infrastructure.

Otherwise, how would you lookup another aggregate root from one aggregate root in the following scenarios: 1. As association (instance variable in class) -
