What are the best practices for layered architecture in software development?

Layered architecture is a design pattern that separates concerns into different layers. Best practices include defining clear responsibilities for each layer, ensuring loose coupling between layers, and using interfaces to communicate between them.

Can you explain the different layers typically involved?

Sure! Typically, there are four layers: Presentation Layer (UI), Business Logic Layer (processing), Data Access Layer (database interactions), and Database Layer (data storage). Each layer has its own responsibilities.

How do I ensure loose coupling between these layers?

You can ensure loose coupling by using interfaces and dependency injection. This allows layers to interact without being tightly bound to each other, making your application more flexible and easier to maintain.

What are some common pitfalls to avoid?

Common pitfalls include over-complicating the architecture, not adhering to the single responsibility principle, and allowing direct access between layers, which can lead to tight coupling.

Can you recommend any resources for further reading?

Absolutely! I recommend 'Clean Architecture' by Robert C. Martin and online courses on platforms like Coursera or Udemy that focus on software architecture.
