A STAR is a standard terminal arrival and a SID a standard terminal Departure. These will be published as such and aircraft fly in accordance with the published procedure. Not every airport has formal published procedures but people still need to get in and out of them. These will be lumped together as arrivals and departures and or directs to connect them to a transition waypoint and an airway. So there will be recognised direct tracks and no doubt vectors to expedite you, but they will not be called SIDS or STARS.
