Re: SQL programming fundamentals

My own, minimally qualified personal opinion is that the more a person knows, the better. But conversely, some things like 'tuple relational calculus' aren't required to perform the job either.

No matter where someone works, or how much they know, each database/system setup is pretty unique, so everybody is always in some kind of learning process (or at least should be). The greater their
'base knowledge', the greater the chance they would need as much
'familiarity training' of that particular database/system, and perhaps
the greater the chance they would have sound, solid advice for improvements to the database/system as well.

But, like everything else, there's always an exception to the rule. Keep in mind my opinion is from the standpoint of someone (actually the only one in my case), working a purely custom database and application. Perhaps others working with more 'pre-canned' software would have a different opinion.
