What is Clean Architecture?

Clean Architecture is an architectural style that separates the concerns of your application into different layers. This makes it easier to test, maintain, and evolve your code.

The four layers of Clean Architecture are:

• The Domain Layer contains the core business logic of your application. This layer should be independent of any other layers, so that it can be reused in other applications.
• The Application Layer contains the code that orchestrates the flow of data between the Domain Layer and the Infrastructure Layer. This layer is responsible for calling the appropriate methods in the Domain Layer and passing the results back to the user.
• The Infrastructure Layer contains the code that interacts with the outside world. This layer is responsible for things like database access, web services, and user interfaces.
• The Presentation Layer is the user interface of your application. This layer is responsible for displaying data to the user and collecting input from the user.
