The Information Overdrive: All About Big Data

What's Big Data Today
Everyday, we create 2.5 quintillion bytes of data–so much that 90% of the data in the world today has been created in the last two years alone. This data comes from everywhere: from sensors used to gather climate information, posts to social media sites, digital pictures and videos posted online, transaction records of online purchases, and from cell phone GPS signals to name a few. This data is big data.
The phrase “Big Data” refers to the tools, processes and procedures allowing an organization to create, manipulate, and manage very large data sets and storage facilities.


Big Data Examples
  • Weather data is collected on a daily basis by the U.S. National Oceanic and Atmospheric Administration (NOAA) to aide in climate, ecosystem, weather and commercial research.
  • The masses of data collected by the U.S. National Aeronautics and Space Administration (NASA) for its research
  • Energy companies have amassed huge amounts of geophysical data.
  • Pharmaceutical companies routinely munch their way through enormous amounts of drug testing data.
  • Data organization maintains in all of its datacenters, regional offices and on all of its user-facing systems (desktops, laptops and handheld devices)
Specific Characteristics of Big Data
  • Volume – Big data comes in one size: large. Enterprises are awash with data, easily amassing terabytes and even petabytes of information.
  • Velocity – Often time-sensitive, big data must be used as it is streaming in to the enterprise in order to maximize its value to the business.
  • Variety – Big data extends beyond structured data, including unstructured data of all varieties: text, audio, video, click streams, log files and more.
Why the Big Data buzz now
  • Large organizations increasingly face the need to maintain large amounts of structured and unstructured data to comply with government regulations.
  • Recent court cases have also lead them to keep large masses of documents, Email messages and other forms of electronic communication that may be required if they face litigation.
  • Big data is likely to be increasingly part of IT world.

  1. The graphical links for comments, facebook, twitter etc should be on the right side of the page, not on the left side blocking text. On the left they cannot be moved out of the way of blocking text; on the right, a reader ca go to a whole page display. If you are doing this for mobile, then how about along the bottom of the display? I could not even publish this without scrolling because I could not see the word "Publish". Otherwise, nice graphic and interesting info, but how about big data info for different markets and industries????
