Ralph Kimball is a person who came up with a really good way of organizing information so that it's easy for people to understand. Imagine if you had a bunch of toys all over your room and you wanted to clean it up. You could put all the stuffed animals in one corner, all the toy cars in another corner, and all the building blocks in a third corner. That way, when you want to play with a specific toy, you know exactly where to find it. This is kind of like what Ralph Kimball did, but with information instead of toys. He helped people put data into categories so they could find it easily and use it to make important decisions. This makes it easier for businesses and organizations to understand how they're doing and figure out what they need to do to get better.
