Ado.Net Entity Data Model RRS feed

  • Question

  • Hi Everyone
    Can anyone explain what is Ado.Net Data Entity Model which is added to visual studio 2008?
    And what's the difference between ADO.Net DataSets and Ado.Net Entity Data Model?
    DataSets in .Net Provide a scheme of the database being interact with, which Data Entity Model does the same thing.
    The only difference that pops into my mind and this very moment is that Datasets provide an offline access to the database recordes and it's a kind of in-memoty architecture to access offline data. But what about Data Entity Models?

    Thanks in Advance. 
    Keep it simple as simple as possible but not simpler.

  • Not really.

    The dataset idea was get a portion of a database but was close to it.

    The EDM is the way to define and manage the model of your application without the constraints of ER. The EF is an ORM (and more) so lets you to manage all the infraestructure to comunicate with the underlying persistence mechanism. But from now EDMX will be the common lenguage to define exchangeable models for all the Microsoft technology.
