I can not find Data Compare in Visual Studio 2012. There is a circuit comparison.
Is it deleted? Or is he hidden somewhere?
Someone has already opened a Connect ticket for this. Microsoft's answer of 3/13/2012 was that they have not yet implemented this feature in the new SQL Server data tools used by Visual Studio 11, but they plan to add them in the future.
Working around using VS 2010 data comparison.
You can install it using SQL Server Data Tools - June 2013

Also see http://msdn.microsoft.com/en-us/data/tools.aspx . This โlooks likeโ replaces the data tools that come with Visual Studio 2010, and how updates are distributed.
We also expect data comparisons!

If you are going against SQL Server 2012, the workaround for comparing VS2010 data will not work. VS2010 Data Compare seems to work only on SQL 2008R2 (and possibly on older versions)
You need to download SSDT to compare sql server data. There is no visual studio in it. However, you can also use the "Master Data" visual studio addin to compare sql server databases .. It is lightweight(1mb) and also includes some additional features over SSDT ..
