ORM即Object-Relational Mapping，对象关系映射。简单理解就是把我们Java的对象与数据库里面的记录进行映射，可以把实体对象持久化到数据库中，也能把查询到的记录映射成Java对象。ORM让我们彻底解放，一点也不需要再去编写冗长晦涩的Sql语句，一切都是通过框架去做，不得不说是程序员的一大福音。 ORM框架实现的原理其实也很简单，就是利用Java的反射机制把对象和数据库记录映射关联起来。比如存储的时候，是把对象的属性取出来作为记录的属性值进行插入；而查询的时候则是把查询条件自动构建成一条Sql语句，把查询到的结果集转成对象列表。J2EE有ibatis，Hibernate框架，我们Android也有GreenDAO，ormlite，xUtils，AFinal等。它们的实现原理都一样，不同的也只是细节方面的处理。如果兴趣的同学，推荐阅读下ActiveAndroid的源码。Reading the fucking code! 以前写过介绍xUtils的系列文章，其中的FinalDb模块就是一个ORM框架，也是我工作中常用的。今天我们介绍的ActiveAndroid的API也是相当的简单友好，而且功能一样的强大。ActiveAndroid简洁的API给人一种用起来很舒服的感觉，今天主要是介绍下关于CRUD的简单使用。 一、初始化 有两种方式
