title: How to develop a CRM system
body: <p>I need to develop a CRM system within 2 months recently. But I'm still a student and have no experience in developing such a complex system. I did alot of researches on how to develop a CRM system, but I face some problems on designing the system.</p>
  
  <p>The problems that I faced are:</p>
  
  <ol>
  <li>Does a CRM system use any framework for development? (eg: DooPHP, Yii, Zend, and so on)</li>
  <li>How to ensure the system is secure? (use OpenSSL?)</li>
  <li>What are the non-functionality that I need to bear in mind?</li>
  </ol>
  
  <p>For your guys information, the CRM that I gonna develop is for a small company use. However, I hope that the system is fast in response and secure, as this is what we want when using a web application. It is ok for me to use PHP, JSP or ASP.Net.</p>
  
  <p>If anyone developed the similar system before, kindly share your experience with us. If possible, share your code here.</p>
  
  <p>Thanks...</p>
