Big Data: NoSQL & the DBA

January 11, 2013 1 comment

Of late, “Big Data” has become one of the hottest topics in the worlds of business and computing.

I’ve done a presentation recently in an internal conference about Big Data, related technologies and how today’s Database Administrators are affected by it. Here’s a background/outline of the talk followed by the presentation itself (slimmed down version).


Customer feedback is very important for any business with out which there cannot be any improvement in the products/services it offers. So, over time, companies have followed several different approaches like in person surveys, random phone calls to customers to get the feedback.

Today, connected devices like mobile phones, tablet PCs, social networks with hundreds of millions of users and various sensors are generating enormous amounts of data (of the orders of hundreds of terabytes to a few petabytes), and at exceptional speeds (A single jet engine on the Boeing 737 generates as much as 240TB of data in a cross-country flight).

So businesses are calling this large volumes of data as “Big Data” and is learning to leverage it for surveys and feedbacks. Therefore it has become highly crucial for the success of any business.

Traditional database softwares are proving to be inefficient to capture and store this avalanche of data. With a little out-of-the-box thinking, the open source community has come up with several systems that can acquire, manage, and process such large volumes. Organizations must make a wise decision in picking a system.

Big Data is also creating several new roles and early birds can make a fortune. 🙂

In this talk, I discussed various technologies available, their working principles and the opportunities available for today’s DBA to explore in this new world of Big Data.
