title: Blog Application: should i embed the comment logic in the main blog entry class?
body: <p>i am trying to write a blog application with CodeIgniter just for practice and using php (of course)</p>
  
  <p>i just wanted to ask that which approach should i choose?</p>
  
  <p>i am planning to write a Blog class with the basic following functions:
  Insert(), Update(), Read(), Delete()</p>
  
  <p>now i want to ask if i should add the comment logic in the main Blog class?
  Such as InsertComment(), UpdateComment() and so on.</p>
  
  <p>Or should i separate it in another class? i am confused because both are inter related and a comment will only be made on a Blog entry.</p>
