Instruction

Now, we'll consolidate our knowledge with four exercises. However, this time we won't explain the tables. This is to better simulate the reality of SQL programming — which is that sometimes, you don't have access to proper database documentation. Don't worry, just take a look at the Database tab on the right: you can easily guess the purpose of each column.

Good luck!
