There's an interesting thread on LinkedIn's TDWI Business Intelligence and Data Warehousing Group I participate in. The point of departure for the discussion is a venting blog by venerable Bill Inmon, often acknowledged as the father of data warehousing, over a marketing ad by Hadoop distribution vendor Cloudera that claims: “CLOUDERA-BIG DATA – Turbocharge your data warehouse”.

Inmon's diatribe takes Cloudera to task for even mentioning big data and the data warehouse in the same breath, the ad's imputed implication being there's a strong affinity between the two, that in fact DW and BD are companion endeavors. Inmon, though, scoffs that BD's simply a technology while the DW's an architecture -- honed over 25 years. “Big Data is good at gobbling up large amounts of data. But analyzing the data, using the data for integrated reporting, and trusting the data as a basis for compliance is simply not in the cards. There simply is not the carefully constructed and carefully maintained infrastructure surrounding Big Data that there is for the data warehouse.”
