There is general consensus that Data Warehousing first appeared in the 1980s. However, the components of Data Warehousing were being thought-through and created as early as the 1960s. There are many different individuals credited with discovering Data Warehousing. Wikipedia has a great chronological timeline that provides a lot of context to the evolution of data warehousing methodologies.
I have added the ‘popular history’ timeline to this blog. IMHO Bill Inmon is the undisputed grandfather of Data Warehousing, and all the rest, even my own contribution in 1983, is relatively light-weight stuff. Go here for the complete Wikipedia article: http://en.wikipedia.org/wiki/Data_warehouse
