A particularly quirky addition to the killer interview questions collection: Explain a database in three sentences to your eight-year-old nephew.

This question comes from a compilation of questions once used by Google that were officially deemed too outrageous by the company to use. Many of them fall into the same category as our recent Killer Interview Question candidate: "How many dollars’ worth of hamburgers are sold in China each day?, where how you derive the answer is more important than its accuracy. For instance: "How many piano tuners are there in the entire world?"
For a technical role, we actually think the database question is very reasonable. Being able to explain technology in straightforward terms is an important skill, but one that's not always encouraged for IT roles. A good answer is likely to draw on real-world analogies, though you'd need to pick those carefully (I suspect most eight-year-olds wouldn't know what a phone book was these days).
How would you answer the question?
