The image shows flow of outside events to Oracle Forms. In the left side of the image, the Oracle Forms has two-way communication with the Advanced Queuing (AQ) functionality of Oracle Database. In the center of the image, the AQ function of Oracle Database also has two-way communication with the possible outside events that can trigger internal Forms events. In the right side of the image, these external events can include technologies such as files with dynamic content, Web services, mail, JMS, or database content that interact with BPEL processes which in turn interact with AQ.
