Instruction
As usual, we'll introduce the tables first. In this part, we're going to work with an online movie store. It boasts the biggest database in our whole course – 6 tables. We'll analyze the tables in a second, but let’s first look at the ER diagram, which we made in Vertabelo.This diagram gives the big picture. After that, we’ll examine the Customer table.
Exercise
Select all the information from the Customer table.
Whoever wants to buy anything in our store needs to register as a customer. Each customer in our system has an Id, a FirstName, a LastName, a JoinDate and a Country.
