## Overview

This is a Spring-based ticket CRUD API. Clients use the ticket endpoints to list tickets with pagination, retrieve one, create, update, or delete; the controller delegates those operations to a service. DTOs represent API data, while a JPA repository operates on ticket entities. The service implementation and application configuration were not excerpted, so its internal calls and persistence wiring cannot be confirmed; the service-to-repository link is shown as unverified.

Main entry points: [`src/main/java/project/practice/controller/TicketController.java`](https://github.com/nikeshjr/ticket-ease/blob/main/src/main/java/project/practice/controller/TicketController.java) (Ticket controller), [`src/main/java/project/practice/service/TicketService.java`](https://github.com/nikeshjr/ticket-ease/blob/main/src/main/java/project/practice/service/TicketService.java) (Ticket service), [`src/main/java/project/practice/repository/TicketRepository.java`](https://github.com/nikeshjr/ticket-ease/blob/main/src/main/java/project/practice/repository/TicketRepository.java) (Ticket repository), [`src/main/java/project/practice/dto/TicketDto.java`](https://github.com/nikeshjr/ticket-ease/blob/main/src/main/java/project/practice/dto/TicketDto.java) (Ticket DTO)

- [Ticket DTO](https://github.com/nikeshjr/ticket-ease/blob/main/src/main/java/project/practice/dto/TicketDto.java): `src/main/java/project/practice/dto/TicketDto.java`

### Application logic

- [Ticket service](https://github.com/nikeshjr/ticket-ease/blob/main/src/main/java/project/practice/service/TicketService.java): `src/main/java/project/practice/service/TicketService.java`

### Ticket persistence

- [Ticket repository](https://github.com/nikeshjr/ticket-ease/blob/main/src/main/java/project/practice/repository/TicketRepository.java): `src/main/java/project/practice/repository/TicketRepository.java`
