title: What is the most efficient way to store tags in a database?
body: <p>I am implementing a tagging system on my website similar to one stackoverflow uses, my question is - what is the most effective way to store tags so that they may be searched and filtered?</p>
  
  <p>My idea is this:</p>
  
  <pre><code>Table: Items
  Columns: Item_ID, Title, Content
  
  Table: Tags
  Columns: Title, Item_ID
  </code></pre>
  
  <p>Is this too slow? Is there a better way?</p>
