What versions of SSMS have an Express edition? I know all the SQL Server versions from 2005 to 2014 have an express edition. This question is specifically about SSMS. There was an SSMS Express 2005, 2008, and 2008 R2, but I haven't found any later version.
The SSMSE was different in what it can manage as documented here.

Now you can use SSMS (SQL Server Management Studio) as a seperate download - SSMS or SQL server 2014 express - SSMSE that will manage all editions of sql server.

Aaron has a really good explanation here with screenshots :-)


  Express version of Management Studio, since 2012 Service Pack 1, has been a fully functional product with absolutely no differences
