Organizations are struggling with big data, which they define as any large-size data store that becomes unmanageable by standard technologies or methods, according to a new survey of 264 data managers and professionals who are subscribers to Database Trends and Applications. The survey was conducted by Unisphere Research, a division of Information Today, Inc., in partnership with MarkLogic in January 2012. Among the key findings uncovered by the survey is the fact that unstructured data is on the rise, and ready to engulf current data management systems. Added to that concern, say respondents, is their belief that management does not understand the challenge that is looming, and is failing to recognize the significance of unstructured data assets to the business.

RainStor, a provider of big data management software, is joining with IBM in the big data market. RainStor will work with IBM to deliver a solution that combines IBM's enterprise-class, Hadoop-based product, InfoSphere BigInsights, with RainStor's Big Data Analytics on Hadoop product to enable faster, more flexible analytics on multi-structured data, without the need to move data out of the Hadoop environment. According to the vendors, the new combined solution can reduce the TCO for customers by significantly reducing physical storage, and also improving the performance of querying and analyzing big data sets across the enterprise.

"Big data" and analytics have become the rage within the executive suite. The promise is immense - harness all the available information within the enterprise, regardless of data model or source, and mine it for insights that can't be seen any other way. In short, senior managers become more effective at business planning, spotting emerging trends and opportunities and anticipating crises because they have the means to see both the metaphorical trees and the forest at the same time. However, big data technologies don't come without a cost.

Google's first "secret sauce" for web search was the innovative PageRank link analysis algorithm which successfully identifies the most relevant pages matching a search term. Google's superior search results were a huge factor in their early success. However, Google could never have achieved their current market dominance without an ability to reliably and quickly return those results. From the beginning, Google needed to handle volumes of data that exceeded the capabilities of existing commercial technologies. Instead, Google leveraged clusters of inexpensive commodity hardware, and created their own software frameworks to sift and index the data. Over time, these techniques evolved into the MapReduce algorithm. MapReduce allows data stored on a distributed file system - such as the Google File System (GFS) - to be processed in parallel by hundreds of thousands of inexpensive computers. Using MapReduce, Google is able to process more than a petabyte (one million GB) of new web data every hour.
