Database Management Views & Functions – SQL 2005

DMV’s are system views and its a new feature started SQL server 2005 with nearly 80 DMVs. DMV’s are system view that surface the internal counters of the database engine help present an easily comprehendible dashboard of the database engine performance that can be used to monitor the health of a server instance, diagnose problems, and tune performance. Unlike tools like Windows System Monitor(perfmon.exe) and SQL Server Profiler that need to be explicitly invoked and setup to collect the data events of interest. DMVs are always active and constantly collecting the performance data for the instance of SQL Server 2005. As the name suggests, DMVs are dynamic in nature, implying that the data they present represents the instantaneous state of the database engine. Because the state is constantly changing, successive queries to the same DMV usually produce different results.
