(2014) Turning the database inside out : Martin Kleppmann

Databases are global, shared, mutable state. That's the way it has been since the 1960s, and no amount of NoSQL has changed that. However, most self-respecting developers have got rid of mutable global variables in their code long ago. So why do we tolerate databases as they are? --- A more promising model, used in some systems, is to think of a database as an always-growing collection of immutable facts. You can query it at some point in time — but that's still old, imperative style thinking. A more fruitful approach is to take the streams of facts as they come in, and functionally process them in real-time.
