How do I implement layered architecture in my application?

Layered architecture involves organizing your application into distinct layers, each with specific responsibilities. Typically, you have a presentation layer, a business logic layer, and a data access layer.

Can you explain the responsibilities of each layer?

Sure! The presentation layer handles user interface and user experience. The business logic layer processes data and enforces business rules. The data access layer manages data storage and retrieval.

What technologies should I use for each layer?

For the presentation layer, you might use frameworks like React or Angular. For the business logic layer, consider using Node.js or Java. For the data access layer, you can use SQL databases like PostgreSQL or NoSQL options like MongoDB.

How do I ensure communication between these layers?

You can use APIs for communication between layers. RESTful APIs are common for this purpose, allowing the presentation layer to interact with the business logic layer seamlessly.
