MS SQL Server is a version of Microsoft's relational database management system (RDBMS) that was ported and made available to Linux operating systems in 2016.

If you did not select this module to be included during the installation process, you must first install the module.

You can find this feature in the menu system at the following location:

Server|Database|MS SQL Server

The first thing you will see is Microsoft's EULA and a form to initialise the SQL server's admin password.
