Becoming a DBA, Part II
+0 Vote Up -0Vote Down

This is a follow-up to part I from last week. You've considered what you want to do, you've looked at your soft skills, and you still want to be a DBA. How then do you get started?

The first thing to do is decide which platform you're going to focus on. Each "flavor" has its own proprietary tools and commands. While all share a basic SQL language foundation, DBCC CHECKDB() doesn't run on MySQL and …
