Recently a tweet caught several people's attention - "Eventually, Hadoop will swallow the EDW". Let us be very clear, the EDW will be needed now and in the future. The premise of an EDW is for processing and storing data for consumption across the Enterprise for Analytical and Reporting purposes. Hadoop is a platform for managing the processing of Big Data, it is not a relational data store and nor is it engineered to replace the EDW. Several people have a similar misconception, but Hadoop and EDW are mutually exclusive platforms and they will be integrated via strong Metadata relationships.

It is true that Hadoop is getting several upgrades and new distributors, but this does not mean you can move all your EDW data into that platform. Structured data is best processed on RDBMS platforms.

You can argue that one needs a hammer to drive a nail into the wall, but what type of hammer, what type of nail and what type of wall, all of these matter.

There are several articles in the internet including presentations from Hadoop community on why EDW. I urge you to do some research and understand the same. Plan on attending TDWI Las Vegas or Chicago this year to learn more on this, or plan to attend Enterprise Data World 2012 in Atlanta. We have several discussions and sessions on this subject.

Bottomline, EDW is here to stay and is nor getting retired soon.

Mr. Krishnan, I agree, people tend to mix concepts and buzzwords. Just like Oracle's exadata won't replace traditional servers running standard RDBMS - for costs' sake. Thank you for clarification.
