Clean Architecture

Clean Architecture is a software architecture that aims to create a separation of concerns and maintainability in software development. It provides a clear structure and guidelines for organizing code and dependencies. The main goal of Clean Architecture is to make the software independent of frameworks, databases, and other external dependencies, allowing for easier testing and flexibility in making changes.

One of the key principles of Clean Architecture is the separation of concerns, which means that different parts of the software should have clear responsibilities and should not be tightly coupled. This allows for easier maintenance and modification of the codebase.

Another important aspect of Clean Architecture is the use of layers. The architecture is divided into different layers, each with its own responsibilities. The most common layers in Clean Architecture are the presentation layer, the domain layer, and the data layer. The presentation layer is responsible for handling user input and displaying output to the user. The domain layer contains the business logic and rules of the application. The data layer is responsible for accessing and manipulating data from external sources, such as databases or APIs.

Clean Architecture also promotes the use of dependency inversion, which means that high-level modules should not depend on low-level modules. Instead, both should depend on abstractions. This allows for easier testing and decoupling of modules.
