Com o SQLModel, podemos usar a **herança** para **evitar duplicação** de todos os campos em todos os casos.

#### `HeroBase` - a classe base { #herobase-the-base-class }

Vamos começar com um modelo `HeroBase` que tem todos os **campos compartilhados** por todos os modelos:

* `name`
* `age`

{* ../../docs_src/sql_databases/tutorial002_an_py310.py ln[7:9] hl[7:9] *}
