Yesterday I attended a session in Palo Alto on the subject of Data Refinery and the speaker was Will Gorman of Pentaho. I did not realize that Pentaho was acquired by Hitachi Data Systems couple of months ago. The terms “data lake” was coined by James Dixon of Pentaho. I wrote a blog on this subject last year. As soon as the term started to appear in the data lexicon, other interesting terms such as “data swamp” appeared.
