title: Best Practices in setting up a Blog data model
body: <p>I have the following setup for my Blog Data Model:</p>
  
  <pre>
  Blog               Articles             Categories
  -----              --------          1  ----------
  ID  \ 1         *  ID            /----- ID
  Name \------------ BlogID       /       Name 
  Owner              Name      * /      
                     CategoryID-/
  </pre>
  
  <p>I'm worried about how this data model matches the 'best practices' for Blogs.  If a Blog is deleted, should all the articles for that blog be deleted? If a Category is deleted, what should happen to the Articles?</p>
  
  <p>Is there a better way? Is there something I'm missing?  What do 'best-practices' suggest to do?</p>
