I just built an app in which you can visually create and model data (think visio in a web browser). It would have been impossible to do in a perfomant manner with a relational database. And I think it is a very cool application
One is a "bidding" app where you have a group of people bidding for resources where multiple people can claim a resource, but only up to a limit. It's designed to allow certain bidders priority and thereafter to be first-come/first serve.
The other is a project where I'm cross-linking similar systems and want to pass resource ownership between them.
"privilege" comes from the Latin words for "private" and "law" (legal) and dates to feudal times. To "claim privilege" meant that you were above the laws that applied to the common people.
My favorite is a chocolate cupcake with white frosting and tiny ad sprinkles.
