Welcome to the Challenge, where you check your fundamental SQL skills and learn a few facts about the cosmos!

David is a 30-year-old man who moved from the city to the countryside last year. Why the countryside? He is interested in astronomy and living in the country gives him opportunities to observe the night sky. January is a particularly good month to do this.

David is just beginning to learn various facts about the cosmos. Help him learn more with the help our database. In this database, you'll find all 88 constellations approved by the International Astronomical Union. You'll also find details about a lot of stars.
