Believe me, there was once last semester when I had a Database Systems exam. So the night before it, I dreamed that my friends and I were breaking in to the college server room, and modifying the redo buffer logs- that is a resolver log of the information you key in which the database uses to rewrite corrupted data if it is shut down improperly.
So our (my) idea was that after modifying the redo buffer logs, my friend over at the main power supply area would cut the power, and restart it. The improper shutdown would erase all uncommitted changes. Then it would use the modified redo logs to rewrite the data, along with our new grades. This is better than directly modifying the data in an active database because it makes note of the change. This would seem like a natural rewrite operation to it.
To get to that, since I was the only one actually breaking in, I had to go through some Pokemon battles and stuff. Like what?
