This architecture can also contain additional open layers, like a service layer, that can be used to access shared services only in the business layer but also get bypassed for speed. The three-layer architecture works as follows: The Presentation layer is the only class that is directly interacted with the user. a 3 tier Architecture is composed by 3 Main Layers.

Spring Boot follows a layered architecture in which each layer communicates with the layer directly below or above (hierarchical structure) it: Presentation layer: This is the user interface of the application that presents the application’s features and data to the user. In three-layer architecture, the Presentation layer doesn’t communicate directly with the Data Access layer. In short, the introduction of a layered architecture can ensure that each layer (as pragmatically as possible) can adhere to the single responsibility principle. On top of this business logic layer, multiple other components could exist in the view layer, e.g. A representation represents a perceptible form of the information carried by a
