Programming language used to interact with SQL Server databases
To download SQL Server Management Studio go to https://docs.microsoft.com/en-us/sql/ssms/download-sql-server-management-studio-ssms. You will download an installer stub, and then you can make choices of which optional components you want. You can add these components later if you wish.
Note that with SSMS alone you will not get anywhere. You will also need SQL Server. You can download any of the Developer editions here: https://www.microsoft.com/en-us/sql-server/sql-server-downloads. If you install SQL Server on your laptop, be sure to first take a look at this page: https://learn.microsoft.com/en-us/troubleshoot/sql/database-engine/database-file-operations/troubleshoot-os-4kb-disk-sector-size. It discusses a known issue which causes the installation of SQL Server to fail under some circumstances. You might as well check before you try installing. As for installing SQL Server, this download, too, is also a stub. You will get three choices: Basic, Custom and Download Media. I very much recommend the latter. If you would have the disk-sector issue that I mentioned when you run Setup you will get a warning. When you select Download Media, you get an ISO. Just double-click the ISO and run Setup.
