What is the difference between a venue and a performance?
As far as Lights Up is concerned, there is no functional difference. Commonly a venue refers to a facility, and a performance to a particular event in that venue. But for Lights Up, every performance is a new deal. It makes no difference where the performance is held, whether it is the same facility or another one — every performance is unique. Seats for Tuesday night have no connection whatsoever to seats for Thursday night, etc. Information on each performance stored in its own database.
