title: Does every user have their own database table?
body: <p>For most major sites that you can preform CRUD operations does each user have their own database table? I would love to see an example of a database structure which multiple users, I'm looking at my wordpress database structure and just can't picture how twitter, tumblr, or even stackoverflow actually runs a database. Is it that easy to create a table for a user dynamically? Thanks in advance.</p>
