In Clean Architecture, entities are domain objects that encapsulate business logic and represent the core concepts of the problem domain. Entities are not dependent on any specific implementation detail or framework and are typically defined as pure data structures. Entities are independent of the application's use cases and the infrastructure.
In Clean Architecture, a data source is a component that provides access to data from external systems such as databases, web services, or file systems. It is responsible for implementing the low-level details of data access, such as opening and closing database connections, executing queries, and handling data serialization and deserialization.
In Clean Architecture, a repository is an interface that defines a set of methods for accessing and managing data. The repository is responsible for abstracting the data layer from the rest of the application and providing a way to perform data operations without knowing how the data is stored or retrieved
In Clean Architecture, a use case is like a mini-program that describes a single task the system has to do. It has all the rules and logic needed to get the task done, and it also says what kind of things it needs to start and finish the task
By employing clean architecture, you can design applications with very low coupling and independent of technical implementation details. That way, the application becomes easy to maintain and flexible to change. Clean architecture allows us to create architectural boundaries between dependencies which allows components to be intrinsically testable
