Traditionally, the realization of application use cases tends to be tightly coupled with the infrastructure because the former makes direct calls to the infrastructure. As an implementation technique, you can use aspects and pointcuts to factor out the infrastructure. On top of that, you need a way to modularize infrastructure concerns. You achieve this with infrastructure use cases. It is common to find the same infrastructure use case being attached to different parts of the application. ...
