Abstract: A message broker data processing method includes steps of: receiving published messages 325 on a topic from a publisher application 31; processing 321 the received messages; and distributing the processed messages to subscriber applications 33,34; where the distributing step is carried out via a plurality of subscription point data processing nodes 323,324, each of which distributes messages to at least one subscriber application which has previously registered a subscription request identifying a specific one of the plurality of subscription point data processing nodes. The processing 321 may be format coversion.

Abstract: A message broker 32 is described that can receive messages on a given topic from a number of publisher applications 31a/b. These messages are received at a plurality of publication points 323/324, which are data processing nodes at the beginning of specific processing paths through the broker. The messages may be processed 321 by the processing path, for example a transformation, before arriving at a subscription point 325. From here the message is forwarded to subscribers 33 interested in the subject matter of the message. The system allows publishers to publish messages in a single format, rather than all the formats required by subscribers, and the use of a single topic name to identify the subject of the message throughout the system, rather than one per format of the message. In the embodiment the system provides stock data to subscribers and the message transformation involves changing the currency that stock prices are quoted in.
