Well for danes it would mean computer science. In 1966 Peter Naur coined the word datalogi (data-logy) which has since been used in danish for the subject computer science.
The data scientists I work with would strongly disagree. I've discussed this a bit on HN, and while the title is a bit nonsensical, it has come to stand for a mix of responsibilities.
Don't take my word for it, though--you should visit us and find out what data scientists do!
