Swetugg Tix is an event-sourced system for managing event tickets. Just getting started though, not much to see here yet.
An Activity is the root of any Tix event. An Activity has a total Seat limit that can be increased or decreased. An Activity can also have one or more TicketTypes. A TicketType can be either limited (only allow a specific number of seat reservations) or unlimited (can be used as long as there are seats left on the activity).
A Order is used to reserve a seat at an Activity. When a Ticket is added to an Order, an attempt will be made to reserve a seat. If the reservation succeeds, the Ticket is confirmed.
