3 tier architecture Obj Issue

Im pretty new to 3 tier arch. I've been reading questions around this topic here at SO and a user response, this page, helped me a lot with a quick an easy example. http://www.beansoftware.com/ASP.NET-Tutorials/Three-Tier-Architecture.aspx

When it explains Business Layer and DAL, the example uses objdt but I don't see it initialized anywhere. It calls a method from DAL so I assume it's a DAL object but again, I can't see the initialization. Then the same object calls a SQL function which is not described in the example but I assume it should go in the DAL class.

Am I wrong or the example is missing something? It would clear my doubts to know what that obj is. Thanks a lot.

business layer:

clsStudentData objdt=new clsStudentData();

data layer:

Create_Connection objdt=new Create_Connection();

If you take a look at the source code, you'll see that objdt is of class clsStudentData. Its being initialized inside of clsStudentInfo

Here's the snippet: (BusinessLayer.cs).

public class clsStudentInfo
    {       
        clsStudentData objdt=new clsStudentData();
            ......

The example on the web page just doesn't show the whole class of clsStudentInfo
