Summary

Instruction

Ok, first things first, as always. Today, we're going to work with a retail store. Let's get to know the tables.

Exercise

Select all the information from the store table.

Each store has its own id, country and city. There is only one store per city in our table to make things a bit easier. Apart from that, you can see when the store was opened and what rating it has (1-5), based on customers' opinions.
