- First, you'll cover the most basic commands and the informational commands--when to use them and how, in order to minimize impact on the solution.
- Next, you'll learn about the maintenance commands and how to recognize when a DBCC command has been superceded by a Dynamic Management Object, along with examples of how to use them.
