Oracle Database Discussions

Hello,

I'm developing an application that queries an Oracle Database to check if a certain field has changed. I've programmed a timer that every 5 minutes queries for that field.
I would like to know if it is possible to do the opposite. I mean, instead of being the application the one who checks for the field, I would like to know if it is possible to create a trigger that once the field has been updated it would create a socket to communicate with the application.
If that is possible, could someone explain how to do that or show me some examples??

Thanks in advance!!!
