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.”
