Object/DataSet Relational Mapping

一 问题提出
1.DataSet中DataRow只能以DataTable[0].Rows[0][“Name”]的方式获取数据
2.Sql配置的不动态，不清晰的Sql拼凑
3.使用JAVA 的ORM设计.Net，使用对象层，每一次修改都将影响反射的对象。
那么请继续看下面的文章

[align=center](对象/数据集关系映射)[/align]
NickLee.ODRM模式可以很好的解决以上问题
1.DataSet中DataRow只能以DataTable[0].Rows[0][“Name”]的方式获取数据
方案：DataRow转化为序列化对象，但序列化对象只作为清晰的对象操作实体处理业务判断和数据
2.Sql配置的不动态，不清晰的Sql拼凑
方案：采用IBatisNet数据层构架，采用IBatisNet动态的SQL语法，但返回DataSet
3.使用JAVA 的ORM设计.Net，使用对象层，每一次修改都将影响反射的对象。
方案：清晰的O(对象层),无反射机制，避免每一次修改对对象层的改动。
下面做详细的说明
以下代码演示将包含在NickLee.Framework.2.0.1.2以上版本中,当然，我们只是提供一种思想，灵活的方案，仅代表TheFallAngel团队的思想。
必须引用的dll
IBatisNet(Version 1.5及其以后) with NickLee.Framework修改版本

1.DataSet中DataRow只能以DataTable[0].Rows[0][“Name”]的方式获取数据
2.Sql配置的不动态，不清晰的Sql拼凑
3.使用JAVA 的ORM设计.Net，使用对象层，每一次修改都将影响反射的对象。
那么请继续看下面的文章
[align=center]Object/DataSet Relational Mapping[/align]
[align=center](对象/数据集关系映射)[/align]
NickLee.ODRM模式可以很好的解决以上问题
1.DataSet中DataRow只能以DataTable[0].Rows[0][“Name”]的方式获取数据
方案：DataRow转化为序列化对象，但序列化对象只作为清晰的对象操作实体处理业务判断和数据
2.Sql配置的不动态，不清晰的Sql拼凑
方案：采用IBatisNet数据层构架，采用IBatisNet动态的SQL语法，但返回DataSet
3.使用JAVA 的ORM设计.Net，使用对象层，每一次修改都将影响反射的对象。
方案：清晰的O(对象层),无反射机制，避免每一次修改对对象层的改动。
下面做详细的说明
以下代码演示将包含在NickLee.Framework.2.0.1.2以上版本中,当然，我们只是提供一种思想，灵活的方案，仅代表TheFallAngel团队的思想。
