因此，`orion_cat.owner.name`可能是该宠物主人的姓名（来自表`owners`中的列`name`）。

它可能有一个像`"Arquilian"`(一种业务逻辑)。

当您尝试从您的宠物对象访问它时，ORM 将完成所有工作以从相应的表*所有者那里再获取信息。*

常见的 ORM 例如：Django-ORM（Django 框架的一部分）、SQLAlchemy ORM（SQLAlchemy 的一部分，独立于框架）和 Peewee（独立于框架）等。

在这里，我们将看到如何使用**SQLAlchemy ORM**。

以类似的方式，您也可以使用任何其他 ORM。

/// tip

在文档中也有一篇使用 Peewee 的等效的文章。

  `Found IT,' the Mouse replied rather crossly:  `of course you
know what "it" means.'

  `I know what "it" means well enough, when I find a thing,' said
the Duck:  `it's generally a frog or a worm.  The question is,
