Big Data vs. the Data Warehouse


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”.

Welcome to the world of heterogeneity. There once was a time when people 'seemed' to believe having a data warehouse would lead to nirvana . . . and a single source of truth. But then the world changed - both on the technology side with incredible improvements in both hardware and software, and in the sophistication of the user and the questions (and queries) that were (and are) being asked.

To think Big Data will replace the data warehouse is most probably a misbegotten notion in my opinion. To think that organizations will begin to use data sets from beyond the data warehouse - data that by it's very nature cannot be easily modeled into the data warehouse - is a reasonable thought. To think that data beyond the data warehouse will not be limited solely to 'Big Data' but will also be complemented by special purpose or niche platforms like Array dbs or other high performance analytic platforms it most likely to see the future. But each of these steps - in hardware, software, modeling, user sophistication - these are not steps to obviate what came before but steps to enhance what is becoming available. That at least, is my humble perspective.
