  1. Creating a contact. Entering information into Edit Contact Information and clicking Create adds a new Contact instance to the database and refreshes GUI to display it.

  2. Deleting a contact. Clicking Delete removes the contact currently displayed in Edit Contact Information and refreshes the GUI so that it no longer displays the contact.
