Increasingly data is being bought and sold online. To facilitate such transactions, online data marketplaces have emerged to provide a service for sellers to price views on their data, and buyers to buy such views. These market-places neither support the sale of ad-hoc queries (that are not one of the specified views), nor do they support queries that join datasets. The authors present QueryMarket, a prototype data marketplace that automatically extrapolates prices to ad-hoc queries, including those with joins, from the manually priced views.
