Abstract
Abstract The present invention relates to messaging systems in general and message broker systems in specific. More particularly, the invention relates to means and a method for processing message publication requests and message subscription requests. The current invention transforms the subscription problem into a database query problem allowing to use query techniques known and optimized for many years. The basic approach of the current invention is to invert the relationship of message publication requests (treated as database data) and message subscription requests (treated as database queries) according the state of the art. Thus the core of the current invention is to treat incoming messages publication requests as database queries and to treat message subscription requests as database queries.
