I spent a majority of my programming career developing business process automation solutions on top of a graph database that incorporated state management in the middleware layer as a first come citizen. State transitions were triggered and it had strict schema. It was amazing the amount of features we could push out with great stability and scalability using this middleware. We build huge systems that just ran like clockwork and was easy to explain and reason about. Sad part of this is that the middleware is not commercially available without buying they vendors domain specific products.
