SQL Server instance features

Installation of SQL should be handled by a trained professional, but the Technet installation guide (https://social.technet.microsoft.com/wiki/contents/articles/34582.sql-2016-step-by-step-guide-installation.aspx) is a good reference.

If the list of features for your SQL Server version does not include the Management Tools entries, download and install SQL Server Management Studio separately, after installing SQL Server: https://docs.microsoft.com/en-us/sql/ssms/download-sql-server-management-studio-ssms.
