## Créer l'application avec un modèle unique { #create-the-app-with-a-single-model }

Nous allons d'abord créer la première version la plus simple de l'application avec un seul modèle **SQLModel**.

Ensuite, nous l'améliorerons en augmentant la sécurité et la polyvalence avec **plusieurs modèles** ci-dessous. 🤓

### Créer les modèles { #create-models }

Importez `SQLModel` et créez un modèle de base de données :

  public C first() {
    // requireNonNull is safe because we checked the range is not empty in ContiguousSet.create.
    return requireNonNull(range.lowerBound.leastValueAbove(domain));
  }

  @Override
  public C last() {
    // requireNonNull is safe because we checked the range is not empty in ContiguousSet.create.
    return requireNonNull(range.upperBound.greatestValueBelow(domain));
  }

  @Override

   */
  public static <T> Optional<T> absent() {
    return Absent.withType();
  }

  /**
   * Returns an {@code Optional} instance containing the given non-null reference. To have {@code
   * null} treated as {@link #absent}, use {@link #fromNullable} instead.
   *
   * <p><b>Comparison to {@code java.util.Optional}:</b> no differences.
   *
   * @throws NullPointerException if {@code reference} is null
   */
