RE: Cary's Book - new topic

Now that the response quality was mentioned, the intimately related topic is the quality of the application itself. I frequently indulge myself into observing things like usability: - Are buttons in the applications created naturally, easy to press   and with good logical explanations?
- Are fields following each other naturally and does the operator have   to use mouse navigation frequently, thus taking fingers off the   keyboard? Are there unnecessary sights and sounds (picturess, beeps,   music, animations) which would unnecessarily burden the LAN? - Are fonts readable and pleasant to work with or is the effect of an   hour in forn the application an equivalent to the punch in the head? - Are scrolling lists searchable and are they big? Do they take long   time to populate?
- Are colors bright and annoying or not? - What is the overall impression of the screen?

My experience tells me that, when it comes to the perception, all of the above plays certain role. People tend to be much less satisfied with annoying and ugly applications and can frequently claim that they're slow. It's not just performance, it's the quality of the application, as well. What Cary's book pointed out and what I objected to is the fact that a DBA (in contrast to Cary, I see that role being identical to the one of a "senior DBA") must be a politician as well as an expert with databases and operating systems. On the other hand, if Arnold can do it, why not me? Hasta la vista, baby.
