对象关系映射架构（DBFramework）及代码生成器源码   http://lknoodle.download.csdn.net/

一、使用对象关系映射组件Kenly.DBFramework.dll不用编写任何SQL或者存储过程即可实现下列功能：
1、数据表、视图和存储过程与对象之间的转换。
2、数据表、视图的自定义条件查询。
3、数据表、视图的分页查询。
4、根据ID、主键或自定义条件对数据表进行增、删、改操作。
5、实现一对一、一对多、多对一和多对多的关系映射。
6、支持单个对象和多个对象之间的事务控制。
7、支持查询结果排序。
8、支持查询表达式生成。
9、支持延迟加载。
 
二、代码生成器
1、根据指定的数据库连接，自动生成数据表、视图和存储过程对应的对象代码（C#代码）。
2、自动生成相关的工程文件，生成完整的业务层项目文件。
3、可以帮助生成自定义查询方法。
4、支持SQLServer2000、SQLServer2005和Oracle代码生成插件，支持插件扩展。

提供
1、对象关系映射组件： Kenly.DBFramework.dll
2、代码生成器源码：CodeHelper。
3、代码生成器插件源码（支持SQLServer2000、SQLServer2005和Oracle）：Plugin。
4、使用手册：DBFramework.Manual V4.5.3.pdf。
