SQL Management Studio

SQL management studio is free and can be found here: https://docs.microsoft.com/en-us/sql/ssms/download-sql-server-management-studio-ssms
The powershell component is no longer part of the Management studio and therefore to use powershell with MsSQL you need the powershell sql ps module: https://docs.microsoft.com/en-us/sql/ssms/download-sql-server-ps-module .
