title: Difference between UML 1 and UML 2? Which one should I be focusing on?
body: <p>I was given a special task to learn and discuss about UML at work. I have a little background about the topic, though I'm not sure what area should I give more priority since UML has now multiple versions. Should I stick with the the UML first version and give an overview for the UML 2 instead? or should I focus more on the UML 2 since it's the latest version? I'm confuse since I'm not familiar with the difference of the two versions. </p>
  
  <p>I need advise regarding the matter. Thank you in advance. Pardon if this question is irrelevant in this site.</p>
