特点 - NHibernate的与编写自定义对象关系映射器 [英] Features - NHibernate versus Writing Custom Object-Relational Mapper
问题描述
我在找的你将有一个自定义的对象关系映射（ORM），以满足NHibernate的所有功能实现的功能列表。
I'm looking for a list of all the features you would have implement in a custom object relational mapper (ORM) to meet all the features of NHibernate.
启动：
- 在数据库可移植性，通过不同的驱动程序和方言
- 缓存
- 延迟加载
- 在自定义的SQL
- 在查询界面 - LINQ，标准，QBE（按实例查询）
- 基本和高级映射功能（例如鉴别列的例子的）
- 支持事务和工作单元
- 多条件
- 多查询
- 配料
- 钩来补充/覆盖功能
- database portability through different drivers and dialects
- caching
- lazy loading
- custom SQL
- query interface - LINQ, Criteria, QBE (Query By Example)
- basic and advanced mapping functionality (ex. discriminator columns, examples)
- support for transactions and unit of work
- Multi-Criteria
- Multi-Query
- Batching
- Hooks to supplement/override functionality

推荐答案
Ayende发表重要ORM近乎完整的列表功能在这里： <一href="http://ayende.com/Blog/archive/2006/05/12/25ReasonsNotToWriteYourOwnObjectRelationalMapper.aspx" rel="nofollow">http://ayende.com/Blog/archive/2006/05/12/25ReasonsNotToWriteYourOwnObjectRelationalMapper.aspx
Ayende published a near complete list of important ORM features here: http://ayende.com/Blog/archive/2006/05/12/25ReasonsNotToWriteYourOwnObjectRelationalMapper.aspx
这是重要的一个是从你的列表中缺少的是IsDirty /状态变化检查。标识映射是另一种重要的使了很多其他的功能，如IsDirty。
An important one that is missing from your list is IsDirty/State Change checking. Identity Map is another important one which enables a lot of the other features such as IsDirty.
