Cleaned-Up Transcript of Rich Hickey's Talk "Deconstructing the Database" · GitHub

What's usually missing is an information model. By an information model, I mean the ability to store facts, to not have things replace other things in place, to have some temporal notion to what's being stored. That's what I would consider a true information model, and that's usually missing from the databases. (View Highlight)

The biggest one by far is definitely the state model. The fact that it's update-in-place. (View Highlight)

To move to an information model means to move to a data model that is fundamentally about facts. (View Highlight)
