What do you mean by Clean Architecture is Screaming?

The concept of "Screaming Architecture" in Clean Architecture, as formulated by Robert C. Martin (Uncle Bob), emphasizes that the architecture of a software application should clearly convey its purpose and domain at a glance, without being obscured by the frameworks or technologies used.

Explanation

1. Intent Over Frameworks:

   • The primary idea is that the top-level structure and names in your application should express the business domain and use cases, not the technical details or frameworks. For example, if you are building a healthcare system, the architecture should immediately indicate that it is a healthcare system, rather than a system built with specific frameworks like Rails or Spring[1][2][6].

2. Domain-Centric Design:

   • The architecture should be organized around the business domain and use cases. This means that when someone looks at the top-level directory structure, they should see terms and structures that reflect the business logic and functionality of the application, such as "PatientManagement" or "BillingSystem", rather than technical terms like "Controllers" or "Services"[4][5][8].

3. Separation of Concerns:

   • Clean Architecture promotes the separation of concerns by dividing the system into layers, each with a specific responsibility. The innermost layers contain the core business logic (entities), while the outer layers handle implementation details like frameworks and databases. This separation ensures that the core business logic remains unaffected by changes in the outer layers[3][5].

4. Flexibility and Maintainability:

   • By focusing on the business domain and use cases, Clean Architecture makes the system more flexible and easier to maintain. Changes in technology or frameworks can be made with minimal impact on the core business logic, ensuring long-...
