Big data has largely been driven by the exploding growth of the Internet. Industry watchers estimate the number of connections to the Internet surpassed the global population in 2008. Projections for 2020 are expected to exceed 50 billion connections. e McKinsey Global Institute has conducted extensive research on big data, and estimated that organizations globally stored more than seven exabytes of new data on disk drives in 2010, while consumers stored more than 6 exabytes of new data on PCs and notebook computers. One exabyte of data is more than four times the amount of data stored in the U.S. Library of Congress, McKinsey has reported. In federal government organizations, market research rm IDC reports data is doubling in size every other year with no slowing in sight. Many organizations in both the public and private sectors face challenges processing the amount of big data produced from sensors and devices, for example, let alone gaining operational value from that data. What makes big data truly big is a question that s not easily answered. According to Ashit Talukder, Information Access Division Chief in NIST s Information Technology Laboratory, big data is di cult to capture, store, search, share and analyze. And it s growing fast. "Big data may include billions to trillions of records, that are loosely structured or often unstructured," Talukder said. e records are largely heterogeneous and multimodal, and may be distributed across a number of networks and/or cloud environments, Talukder continued. e records also tend to have complex interrelationships and come from a wide variety of diverse sources. Meanwhile, a recent survey from AIIM reveals that more than 60% of IT executives would nd it "very useful" to be able to link structured and unstructured datasets. And more than half of the respondents in the same survey said they would nd it "very valuable" (56%) or "hugely valuable" (18%) to be able to carry out sophisticated analytics on unstructured data. e full report, "Big Data -- Extracting value from your digital land lls" can be downloaded from the AIIM website at www.aiim.org/Research/Industry-Watch/ Big-Data-2012.
