Data Capture and Delivery communicates with RFID devices and then communicates that information to WebSphere® Premises Server.
Data Capture and Delivery is organized as a system of agents that use the publish/subscribe model to communicate with each other. Agent to agent communication is done through the notification service built upon the OSGi’s Event Admin Service, which is an open standard communication mechanism. Data Capture and Delivery communicates with WebSphere Premises Server through the MicroBroker, which connects to the remote servers and acts as an embedded gateway that provides quality of service, persistent messaging, and seamless bridging. A notification service to MicroBroker enables the flow of messages between the agents on the Data Capture and Delivery controller and the MicroBroker using the topic names.
When WebSphere Premises Server receives events from Data Capture and Delivery, it processes them using various J2EE components that use application specific interfaces to communicate with the enterprise and business domain.
