## Overview

This is a small Java training-catalog persistence project, not a complete user-facing sales application. Its supported workflow is training CRUD through `TrainingDao`, which obtains JDBC connections and maps database rows to `Training` objects. No sampled application entry point or UI connects a user to that workflow, and `StockTraining` is empty. The database schema file is present, but its contents were not sampled, so schema details and wider sales/order stages are not inferred.

Main entry points: [`Training sales/src/fr/app/dao/TrainingDao.java`](https://github.com/mathieurocancourt/training-sales/blob/main/Training%20sales/src/fr/app/dao/TrainingDao.java) (Training DAO), [`Training sales/src/fr/app/config/DatabaseConnection.java`](https://github.com/mathieurocancourt/training-sales/blob/main/Training%20sales/src/fr/app/config/DatabaseConnection.java) (JDBC connection), [`Training sales/src/fr/app/entities/Training.java`](https://github.com/mathieurocancourt/training-sales/blob/main/Training%20sales/src/fr/app/entities/Training.java) (Training entity)

## Components

### Persistence

- [Training DAO](https://github.com/mathieurocancourt/training-sales/blob/main/Training%20sales/src/fr/app/dao/TrainingDao.java): `Training sales/src/fr/app/dao/TrainingDao.java`
- [JDBC connection](https://github.com/mathieurocancourt/training-sales/blob/main/Training%20sales/src/fr/app/config/DatabaseConnection.java): `Training sales/src/fr/app/config/DatabaseConnection.java`

### Training model

- [Training entity](https://github.com/mathieurocancourt/training-sales/blob/main/Training%20sales/src/fr/app/entities/Training.java): `Training sales/src/fr/app/entities/Training.java`

### Other components

- **Application caller**
- **MariaDB shop**

## Connections

- Training DAO → JDBC connection: gets connection
- JDBC connection → MariaDB shop: connects
- Training DAO → MariaDB shop: CRUD SQL
- Training DAO → Training entity: maps rows
