Before transforming add the attribute 'phone' to the BRANCH and the attribute 'mobile-phone' to the CUSTOMER class. Draw the resulting conceptual schema adding your name, student number and the date to the drawing. Use UMLet and paste images of your drawings into your Microsoft Word document using the template provided.
