SQL Server on real server For a project, I am using Microsoft SQL Server Management Studio to run my database. I connect to this through localhost.
I have written an application using Qt which use this database, but now I am distribute the application. How do I change my database on localhost so that I can connect to it from other computers and have multiple connection to the database at the same time.
The first thing you want to check is if Remote access is enabled on your SQL Server instance. 
If not please configure by following the steps here.
