Or so they are telling us. I've got a little experience with this and it is light years ahead of any other arts-oriented database.

SYSTEM KEEPS TICKET FEES WITHIN REASON
You still have to fork over fat service fees when you buy tickets to commercial rock concerts, theater and other entertainment spectacles. But some of those infuriating "convenience" and handling charges -- which can push ticket costs up as much as 20 or 30 percent -- are decreasing for patrons of some nonprofit arts presenters who have adopted a sophisticated software system called Tessitura.
Created in the late 1990s by New York's Metropolitan Opera as a way to merge its ticketing, marketing, fund-raising and other operations into a single integrated database, Tessitura now is used by more than 90 nonprofit arts organizations around the country and abroad.
Now, new databases are not the most glamorous of products, but believe me when I tell you they are more necessary than some stupid new Nutcracker.
