What are SQL Server Data Tools (SSDT) and Who Needs Them?
By SQL Server MVP Ami Levin
I've recently encountered some confusion regarding one of the new components of SQL Server 2012, the SQL Server Data Tools AKA SSDT. From the questions in the MSDN SQL Server forum which I moderate, I realized that the distinction between SQL Server Management Studio (SSMS) and SSDT is not clear enough to many. I have to agree that Microsoft did leave some space for confusion and a lot of duplicate functionality in both tools so let's try to clear up a bit of this confusion.
Before SQL Server 2012, the only management / development tool that shipped with SQL Server as part of the installation was SSMS. SSMS actually serves 2 main purposes - Management and development. You can manage all your SQL Server instances using graphical tools, wizards and using T-SQL. SSMS also included the visual schema designers (A separate blog topic...), Query designers, scripting features and many others that are used by both DBAs and developers. Read More >>

Article: SQL Server Optimizer - Under the Hood: Partial Aggregates
By Ami Levin, SQL Server MVP
In this series of short articles, we lift the hood of the SQL Server Optimizer to examine a few of the many clever tricks used to optimize query performance. You'll see that the Optimizer does not limit itself to using only the instructions provided by the written query syntax, but can correctly deduce a more efficient approach from information it gleans from the schema, the query and data statistical information.
In Part I, we look at partial aggregate operators - an extremely clever way of downsizing certain large joins into much smaller (and faster) joins. Read More >>
