Entity Framework and layer separation
- by Thomas
I'm trying to work a bit with Entity Framework and I got a question regarding the separation of layers.
I usually use the UI - BLL - DAL approach and I'm wondering how to use EF here.
My DAL would usually be something like
GetPerson(id)
{
// some sql
return new Person(...)
}
BLL:
GetPerson(id)
{
Return personDL.GetPerson(id)
}
UI:
Person p = personBL.GetPerson(id)
My question now is: since EF creates my model and DAL, is it a good idea to wrap EF inside my own DAL or is it just a waste of time?
If I don't need to wrap EF would I still place my Model.esmx inside its own class library or would it be fine to just place it inside my BLL and work some there?
I can't really see the reason to wrap EF inside my own DAL but I want to know what other people are doing.
So instead of having the above, I would leave out the DAL and just do:
BLL:
GetPerson(id)
{
using (TestEntities context = new TestEntities())
{
var result = from p in context.Persons.Where(p => p.Id = id)
select p;
}
}
What to do?
