Microsoft has released a new database management tool called Microsoft SQL Operations Studio. The new studio will run on Windows, Linux and Mac OS, and is free and open source. It can manage on-premises SQL Servers as well as Axure instances. There’s no installer, you just unzip the files and run the EXE to start the studio.
SSMS users will be familiar with most features: Object Explorer, T-SQL code window with Intellisense, backup and restore, and so on.
There is also built-in support for Git source control. You can also create dashboard widgets to display performance and maintenance data, which they call Insight Widgets. Two examples are provided: One to display the slowest queries and one to show the space used by tables. The performance widget runs off of the Query Store data, so that feature must be enabled.
The most interesting feature was the Integrated Terminal, which allows running command lines tasks from within the Studio, including Command Line, Powershell, and BCP.
Operations Studio is still way short of SSMS on features, although I did like the dashboards and the Integrated Terminal. The basics seem to be covered, and I would expect more features to be added over time. I imagine the main use case is for non-Windows users, although a non-admin Windows user that just needed to query data may find use in the simpler version.
