title: Business logic in MVC
body: <p>I have 2 questions:</p>
  
  <p>Q1. Where exactly does "business logic" lie in the MVC pattern? I am confused between Model and Controller.</p>
  
  <p>Q2. Is "business logic" the same as "business rules"? If not, what is the difference?</p>
  
  <p>It would be great if you could explain with a small example.</p>
