It is a set of principles and practices that can be applied to any software project.
Clean architecture is also called onion architecture because the layers are arranged in a circular shape, like an onion. The following diagram shows the typical layers of clean architecture:

The preceding diagram illustrates the dependencies flowing from the outer layers to the inner layers. At the center of the architecture lies the application core layer, which contains the entities and interfaces for business logic. Additionally...
