## Crear la App con un Solo Modelo { #create-the-app-with-a-single-model }

Primero crearemos la versión más simple de la aplicación con un solo modelo de **SQLModel**.

Más adelante la mejoraremos aumentando la seguridad y versatilidad con **múltiples modelos** a continuación. 🤓

Also note that `mc` version `RELEASE.2021-09-02T09-21-27Z` or older supports only a single remote target per bucket. To take advantage of multiple destination replication, use the latest version of `mc`
