Clean Architectures
0 likes52 views
The document discusses software architecture inspired by Robert C. Martin's concepts, emphasizing that architecture should reflect application use cases rather than loud declarations of intent. It highlights the importance of separate application-specific and application-independent business rules and advocates for creating architectures that maximize deferred decision-making for better testability. The content also includes references to relevant resources and videos related to architecture.
Clean Architectures
- 1. About Architectures Largely inspired by Robert C. Martin “Architecture: The Lost Years” R. Ciatti
- 3. The WEB is a delivery mechanism “Web App” a common misconception:
- 4. Architecture has to scream the intent of the application
- 5. Usecases Architecture of an application is driven by use cases USECASE <user_id>, … 1. user issues create booking command 2. Request data validation 3. System confirm booking 1. system show error message … Data Primary course Exception course Ivar Jacobson “Object Oriented Software Engineering” (1992)
- 6. Usecase Application specific business rules e.g.: the booking process for your particular application
- 7. Entity Application independent business rules e.g.: the user entity composed by unique nickname etc…
- 9. Arrows they point away from the usecase
- 10. the big picture
- 11. the flow
- 12. Application reuse Application: agnostic about delivery mechanism can be used with different “communication channels”
- 13. Testability Test in isolation without delivery mech. Usecase business logic testable using Req and Res models
- 14. the database
- 15. Design good architectures to maximize the number of deferred decisions
