Creating Users and Managing Privileges in MySQL

The ability to create users and manage privileges provides a granular level of security and access in MySQL. In this lab, you will be tasked with creating new users in the MySQL server and deleting users that no longer need access. Once the users are created, you will need to grant the appropriate privileges to each user so that they have access to the correct databases and tables within the server.
