Architecture Flashcards
Clean Architecture
consists of concentric circular layers:
inner layers are high-level, abstract policies
outer layers are technical implementation details
loosely coupled
layers (inner to outer):
entities (business objects)
use cases (actions)
interface adapters (bridge between outside world and world inhabited by the use cases and entities-models, views, presenters and repository implementations)
frameworks and drivers (external agents - web, database)
The Dependency Rule: source code dependencies can only point inwards. Nothing in an inner circle can know anything about something in an outer circle.
MVC
Model
central component
application’s dynamic data structure, independent of the user interface
directly manages the data, logic and rules of the application
View
any representation of information such as a chart, diagram or table
multiple views of the same information are possible
Controller
accepts input and converts it to commands for the model or view.
