实体框架自我跟踪实体与工作单元 [英] Entity framework self tracking entities vs Unit of work

问题描述

使用Entity框架自我跟踪实体和实现工作单元架构有什么区别？据我所知，两者都是跟踪对象，一个db调用提交更改。所以我无法弄清楚那些差异。有人可以指出我在哪种情况下应该使用什么？

我正在使用实体框架5和WCF服务应用程序。

What is the difference between using Entity framework self tracking entities and implementing Unit of work architecture? As i understand both are keep tracking of the objects, one db call for commit changes. So i cant figure out the difference of those. can some one point me about what should used in which case?
I'm using entity framework 5 with WCF service application.

推荐答案

我已经找到你的回答，很清楚要理解答案：

1-当你看到它们的目的时，它们是相同的，因为它们会将所有变化一起变为数据库。

2-你可以选择自我跟踪，因为：自我跟踪只需准备好与各种工作能力一起使用（因为它有很多实现的方法）

3-你可以优先选择UnitOfWork，因为：你可以添加你的方法满足您的需求，如RoleBack，但如果您同意当前的实施，也可以将这些添加到selftracking

I have find out your response it is very clear to understand the answer:
1- They are the same when you look thir purpose because they will aply the changes all together to the databse
2- You can prefere Self Tracking because: Self Tracking simply ready to use with a variety of working capasity (Because it has many implemented methods)
3- You can prefere UnitOfWork because: You can add your methods according to your needs as like as RoleBack but also you can add those to the selftracking if you agree current implementation
