@ManfredSteyer Application Domain Infrastructure Isolate your domain! Domain Domain Infrastructure
e. g. data access Application Use case specific facades, state management Entities, biz logic

@ManfredSteyer Alternatives to layering • e. g. Hexagonal Architecture, Clean
Architecture • Anyway: We need to restrict access b/w libraries
