title: Parse Excel data in Java effectivley
body: <p>I'm supposed to realize a Java application that should retrieve data out of an excel spreadsheet and link it to some objects I've already created in order to apply some calculations on them, then display the result .<br></p>
  <h2>About the app</h2>
  <p>==&gt; The excel spreadsheet is a survey to measure a bank's clients satisfaction about the bank's services.<br/>
  ==&gt; The application should parse the data in the spreadsheet, and do some calculations on it.<br/>
  ==&gt; The result should be displayed using an interactive GUI .</p>
  <h2>What I've done so far</h2>
  <p>I've analysed to problem and create all the objects I will need in my application.
  I Actually did some search here on stackoverflow.com and think that Apache POI would be very useful.</p>
  <h2>Where I need help</h2>
  <p>The problem is that I have no idea about what I should begin with .
  Any suggestions on how to accomplish this , what tools, languages, API or design pattern I should use is more than welcome.</p>
