Must-know: An overview of "big data" (Part 2 of 8)
“Big data” and the Services segment
“Big data” as the name suggests, means a collection of data or data sets that is so large and complex that it’s outside the range of on hand database management tools to process. It’s usually unstructured in the sense that it isn’t organized in a predefined manner or a data model. This is the reason why organizations prefer help from organizations that possess domain expertise in “big data” technologies. “Big data” technologies are preferred because they enable organizations to handle huge data sets and generate useful information and insights from it with minimal delay time. Teradata (TDC) and EMC (EMC) are the companies playing an integral role in providing data backup and storage to the “big data” industry.

They integrate the technology and analytic insights into business processes and workflows. Through its results, Wikibon states that in 2013, 72% of the organizations agreed to employ outside professional services to deploy or run “big data” projects. The professional services firms bring business domain knowledge and expertise to “big data” engagements—that’s a key requirement for successful “big data” analysis projects. Wikibon reported that the global “big data” market revenue stood at $18.6 billion in 2013, compared to $11.8 billion in 2012, registering an increase of 58%. Research and markets is of the opinion that it will show a compounded annual growth of 32.14%, from 2013–2018).
