Can you Help Daisy Manage Her Jewelry Store?
You've just been hired as an SQL specialist by Daisy, who runs a store that sells handmade jewelry. Daisy would like to gather some data that will help her to expand the business. Can you find the number of purchases made by each customer? How much do the customers usually spend on a single purchase?
The answers are hidden in the database - you just need to figure out how to get them out!
Hint: In each exercise, you can see a sample of the data. Look in the right-hand menu, under the tab.
Have fun!
