Onion Architecture, Hexagonal Archecture, Screaming Architecture, and others. Models should be persistence ignorant, and encapsulate logic where possible. Due to the loose coupling between outer and inner layers, modifications can be made easier, which can be the difference between an application lasting 2 years and 10 . The software in this layer is a set of adapters that convert data from the format most convenient for the use cases and entities, to the format most convenient for some external agency such as the Database or the Web. Planning to separate this into two articles, and probably video walkthroughs as well. Note the flow of control. NOTE: Although this architecture is language and framework agnostic, I will be mentioning some .NET Framework terms to help illustrate concepts. Clean Architecture combines a group of practices that produce systems with the following characteristics: Testable; UI-independent (the UI can easily be changed without changing the system) Independent of databases, frameworks, external agencies . That would violate The Dependency Rule because it would force an inner circle to know something about an outer circle.
