OK.

I believe it is. The database has no clue as to, say, whether the person named "Joe" actually lives in London. The database can ensure consistency amongst stored facts but there is no way it can verify facts like the one above. Therefore, one cannot guarantee a total absense of dirty data by purely database means. Of course, trivial checks like "age between 1 and 100" or whatever can easily be enforced, but again the database is of no help if the human enters "27" instead of "72".

If you believe otherwise, show how one would solve this problem.

Firstly, let's forget both about my definitions as well as about trying to find out whether those definitions are commonly accepted or not. I withdraw my statement about the definitions being commonly accepted because trying to discuss this point is not very interesting (to me). Secondly, your assertion "Your interest in databases is in the purely formal aspects" is odd since you cannot possibly know what my "interest in databases" might be (you cannot read my mind). Therefore, I'll ignore the assertion as irrelevant.

The phrase is intentionally ambiguous. It can be interpreted in two ways:

  1. "Put up or shut up". Or " you have no clue what you are talking about"
  2. Since I do not see how "semiotics give[s] handles to provide content, context, meaning and use of formal systems", I defer to those who possess such knowledge and am wiling to partake of such knowledge. A facetious way of asking the original question, really [" how "semiotics give[s] handles to provide content, context, meaning and use of formal systems"].

What interpretation is more a propos is actually up to you. Recall, instead of answering my first question about a connection between semiotics and database theory ["for example ?"], you've started theorising on my hypothetical interests in the database theory, i.e. you did not wish or could not answer my question.

Now, can you kindly provide such an answer/example ? Received on Tue Aug 16 2005 - 02:07:12 CEST
