3 tier architecture Obj Issue
<p>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. <a href="http://www.beansoftware.com/ASP.NET-Tutorials/Three-Tier-Architecture.aspx" rel="nofollow">http://www.beansoftware.com/ASP.NET-Tutorials/Three-Tier-Architecture.aspx</a></p>

<p>When it explains Business Layer and DAL, the example uses <strong>objdt</strong> 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.</p>

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