title: one to many vs many to many relationship
body: <p>I just started learning database and I'm confused with using one to many vs many to many relationship.</p>
  
  <p>so I came up with a simple example on the relation beside customer and food.
  Customers orders food.</p>
  
  <p><img src="https://i.stack.imgur.com/1Q22c.png" alt="relationship"></p>
  
  <p>1)If i use one to many relationship, I will say that A customer can order MANY food.</p>

  <p>Base on the above diagram,</p>
  
  <pre><code>1)bob orders noodles and rice
  2)jane orders noodles and crab
  </code></pre>
  
  <p>1)If i use many to many relationship, I will say that MANY customer can order MANY food.

  <pre><code>1)bob orders noodles and rice
  2)jane orders noodles and crab
  </code></pre>
  
  <p>I keep seeing it as the same thing. </p>
  
  <pre><code>bob still orders noodles and rice 
  and 
  jane still orders noodles and crab 
  </code></pre>
  
  <p>regardless whether I use one to many or many to many relationships. correct me if I am wrong.</p>
