Activity 14.01 – creating users for managing the world schema

To manage the database with cities, languages, and countries, you need to set up some accounts. The first account is for the web server user, which should be read-only. The second account is for the intranet user, which is allowed to change and create entries. The third account is for a manager, called Stewart, who is allowed to do everything. As more managers will be hired soon, this should be implemented with roles. The last account is for Sue, who is a language expert and can only change the countrylanguage table.

To complete this activity, perform the following steps:

  1. Connect to the database server.
