Previously database design was handled within Visual Studio so if you wanted to create a database you would use Visual studio and if you wanted to create a SSIS package you would open BIDS. With SSDT the entire set of project related to the database has now been integrated into one set. This means you can now create the MS SQL Server database in the same interface as the packages.
As a result the schema compare feature is also available by default after installing SQL and there is no need for an additional VS interface.

I wouldn't use this in any production code, what with all the SELECT., but for quick interactive querying, there shouldn't be any harm.
