title: Business-Logic refers to Controller or Model. Please elaborate
body: <p>I am confused about what is business logic. I assume that it is written in Controller but then I search it on internet but i found that many person say that it refers to model. I am highly confused. And somee community meembers give me suggestions that my question is same but you are doing mistake. I am confused by the answers in those questions. Someone says model is business logic but I assume that Controller is business logic. So Please understand my doubt.</p>
