Provided are a message brokering systems, computer program products and methods for communication in a publish/subscribe environment in which publisher application programs send messages to subscriber application programs via one or more message brokers, the method comprising the following steps: responsive to receipt of a published message at a message broker, referring to characteristics of the received message and subscriber-specified quality of service requirements to determine an appropriate quality or service for onward transmission of the message; selecting a communication protocol in accordance with the determined quality of service; and transmitting the message using the selected communication protocol. Information relating to the quality of service requirements of a first message broker's subscribers is passed to other brokers and subsequently used for selection of an appropriate communication protocol for transmitting messages between the brokers.

Selection of communication protocol for message transfer based on quality of service requirements

Folders of data from disparate application programs are organized in conformity to a reference taxonomy. A reference taxonomy for representing an organization of stored data found in multiple disparate application programs is created. Each application taxonomy from the multiple disparate application programs is compared to the reference taxonomy by a user. If the user decides to use the reference taxonomy, then the reference taxonomy replaces the application taxonomy for each of the multiple disparate application programs.

Methods, apparatus and computer programs for visualization and management of data organization within a data processing system

Provided are methods, apparatus and computer programs for managing data organisation for computer programs. The method includes generating a reference taxonomy (information defining a first data organisation), accessing storage associated with a message broker to obtain a taxonomy of message topics used by the broker for routing of messages, and comparing the reference and topic taxonomies to identify matching and non-matching features within the taxonomies. The results of the comparison can then be used to generate, in response to selection of a preferred taxonomy, a modified taxonomy to replace either the reference taxonomy or the topic taxonomy. A GUI is provided to display the taxonomies and to facilitate user selections. A set of adapters provide access to the data storage of different programs and obtain taxonomy information for the different programs. A taxonomy engine compares taxonomies to identify differences and similarities, and can be used to generate a new taxonomy.

Methods, apparatus and computer programs for visualization and management of data organisation within a data processing system

A message broker data processing apparatus comprising: a unit for receiving published messages on a topic from a plurality of publisher applications; a unit for processing the received messages; and a unit for distributing the processed messages to a subscriber application; wherein the unit for receiving includes a plurality of publication point data processing nodes, each of which receives published messages on the topic from a publisher application.

Publish/subscribe data processing with publication points for customized message processing

A message broker data processing apparatus has a unit for receiving published messages on a topic from a publisher application; a unit for processing the received messages; and a unit for distributing the processed messages to subscriber applications; wherein the unit for distributing includes a plurality of subscription point data processing nodes, a first subscription point data processing node distributes messages to a subscriber application which has previously registered a subscription request identifying the first subscription point data processing node with the broker apparatus.

Publish/subscribe data processing with subscription points for customized message processing

Provided is a method, system, and program for processing a data flow. A message is received at an input node. The message is transferred to a plurality of nodes according to a defined data flow. At one stored procedure node, the message is processed to generate input parameters for a stored procedure call. The stored procedure node transfers the stored procedure call to a stored procedure at a server computer, wherein the server executes the stored procedure to process data and generate output.
