Can you help Olivia manage her hairdressing salon?
In this story, you've just been hired as an SQL specialist. Are you ready to use your querying skills to help answer the owner’s business questions? Olivia wants to find out which services are the most expensive, how many appointments were made for each day in February, and more.
The answers are hidden in the database; it’s up to you to get them out. Practice your SQL skills and help the shop owners to manage their business!
