Emitting real-time events from database?...

Are there hooks to most modern databases to allow database events to trigger
events or stream data that can be received by Java/C or other languages?

Back in the early/mid 90's Sybase had Open Server which allowed some C-language
integration, but it never really delivered what large enterprises (esp in
financial services companies) needed.

Any pointers are greatly appreciated.

Define your "real time" requirement. Do you need millisecond response?
Microsecond? or is a 1minute refresh rate satisfactory?

People sometimes use real time as a jargon phrase without knowing its
meaning. They usually mean "as fast as possible" which is not a well
defined requirement.

I second that. Here's the definition:

Frank, what is is that you want to do?
