Greetings all.

I ran across DBMS_CHANGE_NOTIFICATION recently. It looks interesting, but I have to ask, aside from refreshing data in some external cache, what good is this really.

I am sure someone can offer up "real world" uses for this database feature? This is just a query of interest. I have no project looking to use the feature yet.

Kevin

Sounds like a nice way to create listeners that wait for messages, rather than procedural triggers.
I can see a lot of uses for this: compare it to a directory-listener that gets triggered if a file is added/changed/whatever.
