title: session variables vs database
body: <p>i'm working on a website for my uni work, and it has to allow login access for different users. My tutor has told me I should be using a session variable/array to store all the users data such as first name, address etc.</p>
  
  <p>In my design I just have the userID and Email address (email is used to login) and then functions to get the data from the database as required. He says this would slow the site down as am doing alot of connections to the database.</p>
  
  <p>Should I store all the data in session variables or connect to the database to access this data?</p>
  
  <p>Thanks for any advice :).</p>
