"I think there’s a lot to be said for looking at a database like a refrigerator. Stuff goes in, stuff comes out, and if stuff stays in too long it becomes unusable. The big difference between MV and relational is one of flexibility. With the flexibility of MV I can open the fridge, grab the lemonade, and close the door without having to really think about it too much. With relational technology, I can’t grab the lemonade without knowing where the lemons are in relation to the water in the door and the sugar in the overhead storage, and that’s just too dang complicated when I’m thirsty."
