Thinking today about a new area to cover on this site and I thought dynamic management views (or DMVs) was a good area to cover next.  I was looking at some documentation today for some DMVs and I realized that there is an easy way to think about them and their function.

• sys.dm_exec_*  These provide information about sessions, connections, query executions and requests.
• sys.dm_os_*  These provide information on OS related information
• sys.dm_io_*  These provide input/output process information
• sys.dm_tran_*  These provide transaction information
• sys.dm_db_*  These provide database information

Enjoy and stay tune for more DMV information.
