# 数据库和Eloquent

Laravel提供了一套与应用程序数据库交互的工具，称为Eloquent，它是Laravel的 ActiveRecord ORM(对象关系映射)

Eloquent是Laravel的一大特点,这也是Laravel与大多数PHP框架不同的特性之一,在数据映射ORM直接中,Eloquent语言以其简单的特性脱颖而出,每一个个表对应一个类，负责检索，表示和维护该表中的数据

但是，无论您是否选择使用Eloquent，您仍然可以从Laravel提供的其他数据库工具中受益匪浅。 因此，在深入了解Eloquent之前，我们将首先介绍Laravel数据库功能的基础知识：迁移，播种和查询构建器

然后我们将会介绍Eloquent,它用于定义模型,插入和更新数据,使用访问,存取,属性转换来自定义你的响应,最后会讨论表关系,这里涵盖了诸多的内容,我相信通过逐步的学习我们能学会的.
