Disclosed is a method which allows an application to request data from other applications using triggering in a messaging environment. Explanation of technologies used A message queue interface, such as the Message Queue Interface, or MQI provided by IBM* Corporation, provides an asynchronous method of communication between programs. An application uses the medium of a queue to communicate with its partner program. These queues can be either local or remote to the application. If an application needs to communicate with another application, it simply PUTs a message to a queue associated with the required application. The application doing the PUT is then free to continue processing. It is not aware that any communications are taking place. Any communications and error recovery are handled by the queue manager . The partner application need not be available when the requesting application executes the PUT. Indeed, the same application can simply communicate with multiple applications by performing PUT operations to different queues.
