Exercise

Create a role

A database role is an entity that contains information that define the role's privileges and interact with the client authentication system. Roles allow you to give different people (and often groups of people) that interact with your data different levels of access.

Imagine you founded a startup. You are about to hire a group of data scientists. You also hired someone named Marta who needs to be able to login to your database. You're also about to hire a database administrator. In this exercise, you will create these roles.
