向我的Entity Framework POCO类添加功能

Question

I've built a web application with Entity Framework using POCO.

I'm using these POCO classes as my business objects and not just for persisting data which works fine until...

Now I need to add some logic into these classes to do thing like total up sales, order lines, etc.

Should I add methods to my POCO classes to enable this functionality or leave them purely for persisting data and create some kind of 'processor' whereby I pass in the business objects and get the values I require out.

Is there a best practice for this?

Answer 1

What is the architectural design you are using or want to use?

For example, if these are your domain entities, you should put as much as possible logic in them. If they are merely data containers and you don't have a real architecture in place, your logic would probably in some business component.

So if you provide your question with some more details, we can help you better.
