Performance dashboard is developed for SQL Server 2005 which provides useful information about the server, in simple it will give you an performance overview of entire SQL Server. If you worked with SQL Server 2005 then you might be familiar with this tool. Unfortunately they didn’t provide or updated the tool to work with SQL Server 2008\R2, however based on user request we have done an workaround to make SQL 2005 reports to work with SQL 2008\R2. The good news is now MS have upgraded performance dashboard to SQL Server 2012 which now includes extended event trace details.
DTA stands for Database Tuning Advisor which has introduced from SQL Server 2005. This utility helps the end user to tune their query and give them suggestions for better performance. It takes T-SQL query or profiler trace as workload, based on this it will analyze and give you the recommendation. Now in SQL Server 2012 it has been extended to include plan cache as workload, which means now you can directly point your db plan cache for analysis.
A new T-SQL feature is available in SQL Server 2008 which allows us to pass a set of rows as a parameter to stored procedures or functions. Table-Valued Parameter (TVP) allows us to send multiple rows of data to a stored procedure or a function without the need to pass so many parameters or creating temp tables.
Most of the SQL Developers/DBA would have come across a situation where they need to store the temporary result sets. This is where Temp tables and Table variables come into effect and helps in storing the data sets in a temporary location.
