Domain-Driven Design: Crafting the Core Business Logic
In the previous chapters, we laid the groundwork for understanding Clean Architecture and its principles. We explored the SOLID principles that guide robust software design and learned how to leverage Python’s type system to create more maintainable code. Now, we turn our attention to the innermost layer of Clean Architecture: the Entity layer, also commonly known as the Domain layer.
The Entity layer represents the core of our application, encapsulating the essential business concepts and rules. This layer is independent of external concerns and forms the foundation upon which the rest of our Clean Architecture is built. By focusing on this core, we ensure that our application remains true to its fundamental purpose, regardless of the technologies or frameworks used in outer layers.
In this chapter, we’ll dive deep into the implementation of the Entity layer, using Domain-Driven Design (DDD) principles....
