    <p>If i get it right you are looking for something like facebook/gmail's real time notification. </p> <p>You can achieve it by implementing several architecture :</p> <ol> <li><strong>Ajax Pooling :</strong> Doing an ajax request after every N (asuume 5) seconds to the server and server will feed you the latest comments. This is the easiest and heaviest way. With a bit of traffic , it will not take a hell lot of time in flooding your server with so many unnecessary request as you will be doing request even if nothing happens.</li> <li><strong>Web Socket :</strong> You can use socket.io and open a socket to relay the updates to the all the clients. This is a common approach to solve this problem. A nifty one too. You can use <a href="https://stackoverflow.com/a/1086448/1426743">this</a> answer to cope up this approach.</li> <li><strong>Reverse Ajax / Comet :</strong> Last one is the toughest one . Facebook uses this architecture and as they are handling a bit of high traffic (:p) we can assume this one has the ability to scale. You can go through <a href="http://www.infoq.com/presentations/Comet-DWR-Joe-Walker" rel="nofollow noreferrer">this</a> video to understand the reverse ajax or comet approach. This <a href="https://stackoverflow.com/a/1086448/1426743">so answer</a> help you to get the idea of it.</li> </ol> <p><strong><em>Update:</em></strong> This <a href="http://techoctave.com/c7/posts/60-simple-long-polling-example-with-javascript-and-jquery" rel="nofollow noreferrer">article</a> seems to give a bit of touch in different techniques to achieve your goal. It might help.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
