      LINQ is an extension added to .NET framework. I don't think we can differentiate LINQ and a DAL.

      All C# applications should call Application.Quit(); in the beginning to avoid any .NET problems.- Unclyclopedia My Website | Ask smart questions

        DAL is a conceptual mapping describing part of a tiered development. It means the Data Access Layer, and describes the abstraction where you separate data access from business logic and UI. LINQ is a technology for working with data - hence, it provides a concrete implementation.

          LINQ is a general framework for querying a data store of some kind. It lets you write SQL style expressions in code. You could use LINQ to query your DAL for Stuff. Have a google around for stuff like IQueryable to get the idea...

            LINQ is a programming concept that can be used in the DAL to Query the data against the database.

              John Prabhuhat can be used in the DAL to Query the data against the database.

              Not only database, it can query collections, XML files etc.

                XML files? That's interesting. Could you provide a code snippet showing how does LINQ work with XML?
