What is Architecture?
Spring Boot follows a layered architecture in which each layer communicates with the layer directly below or above (hierarchical structure) it. The four layers in Spring Boot are as follows:
- Presentation Layer: handles the HTTP requests, translates the JSON parameter to object, and authenticates the request and transfer it to the business layer.
- Business Layer: The business layer handles all the business logic. It consists of service classes and uses services provided by data access layers. It also performs authorization and validation.
- Persistence Layer: The persistence layer contains all the storage logic and translates business objects from and to database rows.
- Database Layer: In the database layer, CRUD (create, retrieve, update, delete) operations are performed.
