I just tried installing SQL Server 2016 Enterprise but I noticed that Management Studio was not installed by default. I also noticed there is a separate link to SSMS in the installation guide which points to https://msdn.microsoft.com/en-us/library/mt238290.aspx
What was the reason for this decision?
The following is noted on the above URL:
This generally available release of SSMS is free and does not require a SQL Server license to install and use.
Perhaps, this is it?
