Yesterday was my birthday. Being born the 14th January makes me a Capricorn according to astrology.
Only there is a slight problem. As told in an article on Huffingtonpost an astronomer has kindly remarked that the assignment of signs with the calendar was made thousands of years ago. In the mean time the earth’s orbit has changed, so we should have completely new signs (and personalities?) today.
I guess astrology qualifies as a data and information quality trainwreck by forgetting one of the most common pitfalls in data quality: Things change.
