Ajax: Increased responsiveness and interactivity of web pages is achieved by exchanging small amounts of data with the server "behind the scenes" so that the entire web page does not have to be reloaded each time there is a need to fetch data from the server. (Wikipedia.org)

As explained in class, it works like this:

1. The user interacts with the page and triggers an event.
2. JavaScript code sends a request to the server, and handles the response.
3. Some server-side code handles the request (get data from database and return to client)
