title: Big data case study or use case example
body: <p>I have read lot of blogs\article on how different type of industries are using Big Data Analytic. But most of these article fails to mention </p>
  
  <ol>
  <li>What kinda data these companies used. What was the size of the data</li>
  <li>What kinda of tools technologies they used to process the data</li>
  <li>What was the problem they were facing and how the insight they got the data helped them to resolve the issue.</li>
  <li>How they selected the tool\technology to suit their need.</li>
  <li>What kinda pattern they identified from the data &amp; what kind of patterns they were looking from the data.</li>
  </ol>
  
  <p>I wonder if someone can provide me answer to all these questions or a link which at-least answer some of the the questions. </p>
  
  <p>It would be great if someone share how finance industry is making use of Big Data Analytic.</p>
