I apologize in advance for my comments (a little bit), and mean no insult directly at any DBA but...
Do you ever take a moment and think about how many DBA's go to work every day and work with the most mundane data? Are you aware that not everyone is going to work at the CIA every day? Have ever thought about men and women who are DBAs or workers using SQL Server who count widgets day-in and day-out? This is something that just drives me nuts about some DBAs and some of the authors who and pretend that every byte of data in the world is somehow 'vital' and at risk.
Consider: I have a buddy who is a DBA for a convenience store company. As he likes to say, he counts Milkbones and the over-blown price for them that you pay when you forget to pick them up during your normal shopping. Yes, instead of 2 dollars at the supermarket, you are going to pay 5 dollars for forgetting them in your weekly shopping. God forbid that Al-Queda ever discover that you, a witless servant of democracy, are getting ripped-off royally should you forget these treats for your dog. My God, the whole great American/European society might come to a stand-still!!!
I am all for prudence and good habits when it comes to data confidentiality. It should be a given for any DBA. But do we have to keep pretending that every DBA working in the world is somehow working with vital and sensitive data? Hello!!! Guess what - many are not. Many do great work, pay good attention to the tenets of confidentiality and security, and yet process some of the most boring, unsensitive and useless data - like counting widgets. Lord help us if some terror group every finds out that Acme company produced 1,000 extra widgets this month!!! Let alone that they should discover that this month's widget production run included a new 1 millimeter change in the diameter of the widget.
This is why many DBAs are looked at as overly full of themselves by their co-workers. They puff up their chests in front of the boss, go on for hours about some new security thingy they just implemented, while people in the room scratch their heads wondering what evil force in the world is trying to crack into their systems to figure out how many widgets, or donuts, or Milkbones they are selling each month.
Sheesh!!! Ever wonder why the world is paranoid?
...again, sorry for the rant - but this has to be said in respect for hard working DBAs who are not working with James Bond and MI6 or the CIA.
There's no such thing as dumb questions, only poorly thought-out answers...
