Things and Stuff 2.0
Things and Stuff is a database application. In a Things and Stuff application, everything is either a Thing, or Stuff about the Thing. For example in the Contacts example, the Kinds of things are People, States, Organizations and so on. Stuff are the attributes (or properties) about the things. For example, the stuff of a person would be their date of birth, address, and so on. This is similar to object oriented models of objects, properties and methods.
