Can you explain what is meant by the concept of clean architecture in software development?

Clean architecture is an approach to software design aimed at creating systems with clear separation of responsibilities and independence of components from implementation details.

Main ideas:

• Business rules (domain) are at the center and do not depend on external layers.
• External layers (interfaces, databases, UI) depend on internal layers, but not vice versa.
• Use of abstractions and interfaces for interaction between layers.

This allows easy changing of external technologies without affecting business logic, improves testability and maintainability of the code.
