title: "pushing" changes in a database to a web page without refreshing
body: <p>I am looking to learn about AJAX and I have what I think is a simple problem that can teach me. Suppose I have a table in a database into which new entries are being added by users. I want to construct a web page that will display the latest n entries, as new entries are added, without refreshing the entire page. Where should I start with this problem?</p>
