This adapter implements the Outbound Port using Spring Data JPA. Note how we map our domain model to a separate database entity to prevent database annotations from contaminating our domain model.

We start by creating a pure Java object representing our business entity. Notice the lack of @Entity or @Table annotations. This adapter implements the Outbound Port using Spring

These define how the domain persists or fetches data, without caring about the implementation. Notice the lack of @Entity or @Table annotations

Domain objects that contain both data and business rules. The hexagon shape is a visual metaphor

The hexagon shape is a visual metaphor. The sides of the hexagon represent the various entry and exit points (Ports) where the outside world interacts with the application core. It highlights that an application has multiple, equal-sided interactions, rather than a rigid top-down approach. 2. Hexagonal vs. Traditional Layered Architecture

Hexagonal Architecture is an architectural pattern that was first introduced by Alistair Cockburn in 2005. The pattern is called "hexagonal" because it visualizes the architecture as a hexagon with the core business logic at its center. The hexagon is surrounded by ports and adapters that interact with the outside world.

Minor overhead due to continuous object mapping. 🚀 Conclusion
