What are the best practices for layered architecture?

Layered architecture promotes separation of concerns. Key practices include defining clear layers, using interfaces, and ensuring loose coupling.

Can you explain the different layers in a typical layered architecture?

Sure! Typically, you have the presentation layer, business logic layer, data access layer, and sometimes a service layer.

How do I ensure loose coupling between these layers?

You can achieve loose coupling by using interfaces and dependency injection, which allows layers to interact without direct dependencies.

What are some common pitfalls to avoid in layered architecture?

Common pitfalls include tight coupling, violating layer boundaries, and over-complicating the architecture with unnecessary layers.
