While tracking a site I came to know that Microsoft has launched a new server for SQL LINK
My queries:
Is “Denali” is SQL SERVER 2011 ? I mean is it a stand alone server or just a feature addition to SQL Server 2008?
If “Denali” is new version of SQL Server. Than do I need to uninstall SQL Server 2005 [which is present in my system] before installing “Denali” ?
Yes, Microsoft SQL Server 2012 is codenamed “Denali”. That means the internal name for the project is “Denali” and this is what MS employees refer to when talking about the new version of the SQL Server.
We don’t know for sure whether the name will be SQL Server 2012, hence the code name.
A community technology preview version (beta) is provided by Microsoft to see the new upcoming features.
As for your questions: Denali might be SQL Server 2011, but they also might change the naming to be SQL Server 20[somethingelse]. Denali is a standalone server and not an add-on. It will be the new SQL Server 2005/2008.
Second question, will you need to uninstall SQL Server 2005 – depends. If you want to use the new features of SQL Server “Denali” or SQL Server 2008 you would need to install these, but can keep using the SQL Server 2005 (not recommended, though).
