FAQPage Schema

What is separation of concerns in software architecture?▼

Separation of concerns is a design principle that organizes codebases by enforcing clear boundaries between modules and layers, requiring the discipline to separate policy from mechanism, data access from business logic, and input parsing from processing.

How do I separate business logic from data access when refactoring a feature?▼

To separate business logic from data access, apply layered design rules that isolate data handling from domain logic, keeping policy separate from mechanism. This discipline reduces coupling and clarifies code boundaries across frontend, backend, and service layers.

Can I apply separation of concerns to both frontend and backend codebases?▼

Yes, separation of concerns applies across frontend, backend, and service-oriented architectures. It guides splitting concerns into presentation, business logic, and data access layers, with rules adaptable to your detected stack and project conventions.

What's the best way to organize code layers in a service-oriented architecture?▼

The best way to organize code layers in a service-oriented architecture is to enforce clear module boundaries that separate policy from mechanism and isolate data handling from domain logic, reducing coupling and improving overall maintainability.

When should I not use a strict layered design for code organization?▼

A strict layered design may not be suitable when project conventions demand tight coupling between presentation and domain logic. Forcing boundaries in simple scripts or prototypes can introduce unnecessary complexity, though the guidance adapts to detected stack patterns.
