## What can you do with Ajax?

- Partial update of page
- Periodic polling for new/changed data
- "Event"-driven interaction (instead of 'form submit'-driven)
  - click, mouseover, submit, etc.
- Incorporate data and functionality from other sites into your web site
  - Your data + functionality from elsewhere
  - Your functionality + data from elsewhere

Ajax is a term coined around 2005 - see Ajax: A New Approach to Web Applications by Jesse James Garrett
