Architecture-Principles

Designing Robust Software with Clean Architecture Principles Designing robust software starts with a clear boundary between what matters to the business and the tools we use to run it. Clean Architecture helps teams keep the core rules independent from UI, databases, or frameworks. This separation makes the code easier to read, test, and change over time, even as teams and tech stacks evolve. A typical layout has four zones: Entities (core business objects), Use Cases (application logic), Interface Adapters (controllers, presenters, mappers), and Frameworks & Drivers (web frameworks, databases, devices). The Dependency Rule states that source code dependencies point inwards. In practice, that means inner layers define contracts and outer layers implement them. The core never reaches outward to depend on details from the outside world. ...
