The core business logic is the domain of the application. It represents the business rules and processes that the application implements. In Java, this can be represented by a simple domain model:

Using module-info.java to enforce encapsulation, ensuring the core cannot accidentally depend on adapters.

: This is the heart of your application. It contains the business rules, entities, and use cases. In Java, this should ideally be "Plain Old Java Objects" (POJOs) with no dependencies on frameworks like Spring or Hibernate.

The hexagonal architecture offers several benefits, including: Do you need an example of to database rows

You can also explore online courses and tutorials on platforms like:

public interface PaymentPort void processPayment(Payment payment); In Java, this should ideally be "Plain Old

: Define what the application needs from external systems (e.g., a CustomerRepository interface).

This book is a guide for architects and developers to build systems that are easy to refactor and maintain by decoupling business logic from technology. First Edition (2022):

And finally, the using Spring Data JPA. Note the complete decoupling: the database entity is separate from our domain model.
