backend-architecture

To structure backend layers, define domain, application, interface, and infrastructure layers, then identify clear boundaries between components. This knowledge graph provides structured guidance on layering and boundary placement to ensure proper separation of concerns in backend architecture design.

The correct dependency direction in layered architecture flows inward toward the domain layer, with outer layers depending on abstractions rather than concrete implementations. This Skill offers guidance on dependency inversion and managing abstraction boundaries to maintain a clean backend architecture.

You need Domain-Driven Design for boundary identification when designing complex backend systems that require clear separation between domain logic and infrastructure. This Skill leverages DDD principles to help identify and define explicit boundaries between components and architectural layers.

Yes, this backend architecture knowledge graph integrates concepts applicable to FastAPI and Spring frameworks. It requires knowledge of Python architecture patterns and Modern Java backend code-quality graphs to output structured answers emphasizing dependency management and boundary placement.

The best way to manage dependencies across backend layers is to apply dependency inversion and define abstraction boundaries between the interface, application, domain, and infrastructure layers. This Skill provides a knowledge graph that guides dependency direction and boundary identification for system design.
