Feeding a message broker by analysis of a database log

Problem

Keeping different users (people or programs) informed of
'interesting' database changes.

Generating 'in flight' information from database updates.
Background

     Certain products exist today that operate by analysis of the
database log to capture 'interesting' database events.

     Typically, these products are used for database replication.
Disclosure

     The same log interpretation can be used to capture data, and
feed it to a message broker.

     The message broker is able to make much more sophisticated
use of the information captured from the log.

   In particular, it can:
treat it as a publication, and send different log event types

to different subscribers.
use data transformation and augmentatoin methods to provide

data in a more directly usable form by the receiver of the
data.

     Reuse of log interpretation code of existing replication
systems with restructure and pub/sub code of existing message
brokers.
