## 🏗️ Architecture

The application follows a structured, layered approach to ensure separation of concerns and clean code organization:

* Controller Layer: Manages HTTP requests and directs them to appropriate service methods.

* Service Layer: Contains business logic and validations.

* Data Access Layer (DAO): Communicates with the database using Spring Data JPA.

* Entity Layer: JPA entities representing database tables.

* DTO Layer: For data transfer between different layers.

* Global Exception Handling: Provides centralized error and exception handling to ensure a smooth experience.
