Can XI be Event Driven?

Hi,

Our scenario is :

Database <----

XI <----

-

R/3 System.

In the current situation the XI is polling the database for every 10 seconds

(this value "10 seconds" is specified in the jdbc adapter configuration file).

I wanted to know whether there is any way the database can trigger XI? In the sense

when ever the database gets updated(or gets modified) can the database produce an event that trigger?s XI.

Thanks
