Using association as a way for achieving dynamic generation of columns in the table in the DB

Hi Guys,
Below I have two classes Customer and CustomerAttributes, now my main requirement for including these classes is to use association(vertical tables) in order to achieve my goal of generating columns dynamically in the table in the DB. Now I am not sure how to go about achieving this as these two classes were given to me on the forum and I am unsure as to how do I go about achieving my goal.

Public Class CustomerAttribute

        Private m_CustomerId As String
        Private m_AttributeName As String
        Private m_AttributeValue As String

        Public Property CustomerAttributeId As String
