Imagine you have a bank vault (production data base). The bank vaults location is NewYork/Bankstreet/Vault7.
You also are testing a new door for your vault. So you build an identical building next door (test data base). Its at NewYork/Bankstreet/Vault8. Only the door installers, and people to test that door are allowed in the building. All your customers go to Vault 7.
Now you make a mistake. You call your builders, and tell them: “The new vault door doesn’t work, we will start over with a different design! Demolish NewYork/Bankstreet!”. Oops, you forgot to put “/Vault8” behind it. And sadly your builders are stupid, they just do what they are told.
So the next day you go to NewYork/Bankstreet and what do you see? They have demolished both of your buildings! Maybe they even demolished the whole street!
Your customers are complaining they can’t access their stuff in your vault. If the whole street is gone you have a real big disaster.
Imagine if you told them to delete “NewYork”, then the mayor (CEO) may knock on your door.
Hopefully the city made a photo (backup) of the city every now and then, and it can quickly be rebuild the way it was in the last photo. Still, untill that’s done it might take some days too, and people are without access to their stuff. (Let’s assume you have robots that can rebuild stuff super fast and accurately).
Oh, and if your city is not incompetently run, you wouldn’t even have the right to order the whole city demolished. The builders would say: Nope can’t do the police won’t let us. Only the mayor can order the City demolished. You only have a permit for NewYork/BankstreetVault7 and NewYork/BankstreetVault8. And they might have standing orders to always ask for a passcode before demolishing the Vault 7.
