How do I detect inserted record or updated record dynamic in oracle?

hi

I need some helps to find solution for
detecting inserted or updated record in the table.

If I have to use trigger, how can I use it?

For example, I connect DB(oracle) and one Web page in php. In this php page, it must check one table if it is changed or not.
if it is changed I must detect dymanically and automatically reflect and show the changed record on the web page.

Can you have some idea to solve this problem? with java applet, is it possible too??

thanks
