Hello all ! The adapter layer corresponds to the infrastructure and the interfaces layer combined from the ddd sample architecture diagram. It's still not a good idea to allow UI components to depend directly on the Data Access layer; it would couple such components together, and you might accidentally bypass important business logic. Both approaches rely on creating a “context bubble”, decoupled from the real world by an abstraction, and plugged back to the real world by an adaptation layer. domain expert A member of the software project whose field is the domain of the application, rather than software development.

The hexagonal architecture, or ports and adapters architecture, is an architectural pattern used in software design.It aims at creating loosely coupled application components that can be easily connected to their software environment by means of ports and adapters.This makes components exchangeable at any level and facilitates test automation. This looks clean and logical until you realize that storing your domain object in memory might hurt performance if the domain object happens to be too large, and even more so fetching such domain object from persistent storage/network.
