The Principle of Bitmaporality

The final principle is really this sense of work where when you have an event in the event log, it is a useful property of the system. So for example, if somebody is disputing why a loan application has been refused, you can say, well, let's just replay that. Let's go back in time. We'll find the loan application. We'll see exactly what decision was made at the time and be able to replay and understand why that loan application was declined. This is the principle of bitemporality. Not every systems need this, but I think it's a very nice property to have once you have all of these other properties.
