Auctions (or more generally events) are central to Auctria.
You may run multiple auctions a year, or have a single annual event. An auction may be a traditional event occurring on a specific day, or an online auction that spans multiple weeks, or a combination of the two.
Each auction contains information relating to that event. Most of the data in Auctria is stored per-auction, including: items, bidders, expenses, bids & payments. However some data is stored per-organization, notably donors and users.
Auctions are created for an Organization. Each organization can have multiple auctions.
