Spring Boot Architecture
Understand the layered architecture of a Spring Boot application.
Layers in Spring Boot
Spring Boot follows a typical 3-layer architecture:
1. Presentation Layer (Controller): Handles HTTP requests/responses
2. Business Layer (Service): Contains business logic
3. Data Access Layer (Repository): Interacts with the database

Each layer has a single responsibility, making the code maintainable and testable.
