Answer 2, Authority 25%
I’ll clarify a little answer – IDE – MS SQL Management Studio – Complete with all versions of MS SQL Server, except the Express version – is sufficiently convenient for development (especially if adddons) is usually used to it.

There is also an alternative to SSMS – DBForge Studio for SQL Server . Personally, I did not use her, but according to reviews they say cool. She is paid, but there is an option if I’m not mistaken, free (in no commercial purposes for one developer). In general, you can look about it information.
Answer 4
I really like Heidisql, too, free.
