The Addresses command opens an Dictionary menu: Addresses submenu of pre-defined and user-defined commands used for tracking requirements, business objectives and goals, and any other information that is useful to know when you are working on your project. An Addresses type of definition can stand alone or it can be attached to a symbol. A stand-alone definition can be defined before you begin to diagram using any methodology. For example, defining your project requirements can be done before you begin the modeling phase.
