数据层架构 [英] Data Layer architecture
问题描述
嘿伙计们，
我刚刚介绍了数据映射器（DTO mapper）。所以现在我使用DTOMapper使用了一个SqlHelper，然后当需要将对象持久保存到数据库或加载它们时，使用DTOMapper将业务层用于
回来了。到目前为止，一切都很顺利。我的问题是，是否可以
练习使用DTOMapper rfom表示层？例如，如果
我想以HTML格式呈现我的数据库中的条目列表，
我应该从演示文稿中使用DTOmapper，还是使用条目
收集方法，内部使用DTOMapper。
第二个选项听起来更清洁，更分离。只想要
看看你们的想法...
谢谢！

Hey guys,
I just recently got introduced to data mappers (DTO mapper). So now I
have a SqlHelper being used by DTOMapper and then business layer is
using DTOMapper when it needs to persist object to database or load them
back. Everything is working nicely so far. My question is, is it OK
practice to use DTOMapper rfom the presentation layer? For instance, if
I want to present in HTML format the list of entries in my database,
should I use DTOmapper from the presentation, or instead use Entries
collection method which internally uses DTOMapper.
THe second option sounds more cleaner and more seperated. Just want to
see what you guys think...
Thanks!

当然发送选项是最好的。我认为架构应该是
看起来像：
演示层
|
业务逻辑层
|
数据访问层
查看MS'的PetShop示例，您的想法会更清晰。

Hi,
Of course the send option is the best. I thinkd the architecture should
looks like:
presentation layer
|
business logic layer
|
data access layer
Check MS''s PetShop sample, you will get your idea clearer.
