@David Thank you for your replay and sorry for my late response. The first link is No, The second link I did not understand what they are suggesting (my lake of knowledge maybe). The third link contains exactly what I asked for.. Thanks

I can create 3rd DL?
Public Class dal3_class
Private _DbEngine As String
Sub New(DbEngine As String)
_DbEngine = DbEngine
End Sub
Function GetTable_ITEM As DataTable
Select Case _DbEngine
Case "A"
Dim o As New Access_Class
Dim dt = o.GetTable_ITEM
Return o
Case "S"
Dim o As New SqlServer_Class
Dim dt = o.GetTable_ITEM
Return o
End Select
End Function
End Class
Is this a good concept?
