The ticket is RT's primary object, and everything that is managed by RT is contained in a ticket. A ticket represents a request, bug report, incident, work order, project, lunch order, or whatever you're tracking with RT. As a user, most of your activity is ultimately about manipulating tickets. A ticket is identified by number and has a set of attributes, such as the subject or summary, who opened it, when it was opened, the priority of the request, and the current status. Some of these values will change over the lifespan of the ticket, such as the status, while some, such as the date the ticket was originally created, can't be altered.
