  Not in their current form : we got relational systems in 1970, but data warehousing came in in the mid 90's. The use of data for multiple purposes (not just to underpin one grand application) is relatively new - as is the practice of using data for a purpose for which it was not gathered... remember all the "all the statistician can do is pronounce what has gone wrong" stuff?
