Interesting point. As with your previous comment on functional languages, I'd argue declarative query languages are more about a difference in thought process.

Interesting point. As with your previous comment on functional languages, I'd argue declarative query languages are more about a difference in thought process. Query languages definitely have a major shift in syntax, but I think the more significant shift is in the theory. One thing absent from my article is addressing the major categorical differences of programming language types. Perhaps I will post an update to address the topic of imperative vs. functional vs. declarative.
