Esto también significa que, en muchos casos, puedes pasar el mismo objeto que obtienes de un request **directamente a la base de datos**, ya que todo se valida automáticamente.

Lo mismo aplica al revés, en muchos casos puedes simplemente pasar el objeto que obtienes de la base de datos **directamente al cliente**.
