<- As far as logical sophistication of users goes, I don't any qualitative <- difference between databases and knowledge bases. To really understand <- either one, and, in particular, to understand querying of either one, <- requires a certain level of understanding of their underlying formalisms. <- The only qualitative advantage that databases may have is one of <- familiarity. Hang on a second - who are the users? Surely as humans we will be dealing with a layer (several layers) above the underlying formalisms. Ok, so underneath it all there may not be any qualitive difference (though there could be - you don't often find Bayesian probabilities and fuzzy truth values in databases), - assuming there isn't then the logical sophistication won't be different. But from the human perspective, which requires more sophistication : SELECT * FROM people WHERE father > 1 Who do you know with more than one father?
