Internet of Things Application Technology Competition - Adding New User Mapping to the Database

Use the sa account to log in to the database on the server computer to complete the
addition of the new retail store database and smart municipal database. Note: If these two databases are not added successfully, some subsequent tasks will be affected.
Create a new user named "dbUser" + [two-digit workstation number] in the database on the server computer, with a
password of 123456. For example: Workstation 08, the new user name is dbUser08. Please map the newly added database user to the new retail store database and add the db_owner role.

1. Create a new user dbUser08 (now in sa user login)


2. Add the user to map to the new retail store database and add the db_owner role
