## Overview

This is a small Spring Data learning project centered on a Flight entity and a Spring Data repository. Its runtime entry point starts the Spring Boot application; the repository extends CrudRepository and declares derived queries over Flight fields. The excerpts show no service layer, API endpoints, or database configuration, so those are not represented as runtime components. The entity-to-repository relationship is evidenced by the repository’s import and generic type; broader application wiring is not shown.

Main entry points: [`src/main/java/com/pluralsight/spring_data_overview/repository/FlightRepository.java`](https://github.com/k90262/spring-data-overview/blob/master/src/main/java/com/pluralsight/spring_data_overview/repository/FlightRepository.java) (Flight repository), [`src/main/java/com/pluralsight/spring_data_overview/SpringDataOverviewApplication.java`](https://github.com/k90262/spring-data-overview/blob/master/src/main/java/com/pluralsight/spring_data_overview/SpringDataOverviewApplication.java) (Spring Boot app), [`src/main/java/com/pluralsight/spring_data_overview/entity/Flight.java`](https://github.com/k90262/spring-data-overview/blob/master/src/main/java/com/pluralsight/spring_data_overview/entity/Flight.java) (Flight entity)

## Components

### Application runtime

- [Spring Boot app](https://github.com/k90262/spring-data-overview/blob/master/src/main/java/com/pluralsight/spring_data_overview/SpringDataOverviewApplication.java): `src/main/java/com/pluralsight/spring_data_overview/SpringDataOverviewApplication.java`

### Flight data

- [Flight repository](https://github.com/k90262/spring-data-overview/blob/master/src/main/java/com/pluralsight/spring_data_overview/repository/FlightRepository.java): `src/main/java/com/pluralsight/spring_data_overview/repository/FlightRepository.java`
- [Flight entity](https://github.com/k90262/spring-data-overview/blob/master/src/main/java/com/pluralsight/spring_data_overview/entity/Flight.java): `src/main/java/com/pluralsight/spring_data_overview/entity/Flight.java`

### Other components

- **Launcher**

## Connections

- Launcher → Spring Boot app: starts (evidence: `src/main/java/com/pluralsight/spring_data_overview/SpringDataOverviewApplication.java`)
- Flight repository → Flight entity: queries (evidence: `src/main/java/com/pluralsight/spring_data_overview/repository/FlightRepository.java`)
