Data analysts, as I prefer to use the term, try to make sense of data which originate from observations, and use whatever is learned from that excercise to their advantage. To achieve some purpose.
You can do that in several ways, like stock brokers why try to play the market in order to make a profit, or like myself who is supposed use remote sensing techniques to learn something about the natural world. I've done a lot of programming as part of the endeavour of developing data analyst methods, and so have had to learn system design and analysis as on-the-job-training.
I am saying I am 'supposed to analyze data' since my work is more and more hampered by the sheer administration-by- manhandling of data. There is less and less time for doing useful work, hence my interest in databases.

Actually, no. It is not fun to discover that either one's native language is insufficient to express an idea, or alternatively, that one does not master one's native language sufficiently well.
