Publication Service and Subscription Service

The figure: Typical Publication-Subscription Services Flow illustrates a typical data flow in Publication Service and Subscription Service when using a standalone adapter. Database Application 1 updates a table in a database monitored by Publication Service. The adapter extracts data from the changed rows of the database tables and publishes it on the specified transport type (TIBCO Rendezvous or TIBCO Enterprise Message Service). This data is then available to other applications listening on the messaging transport.

One particular type of listening application can be another instance of a TIBCO ActiveMatrix Adapter for Database adapter that runs Subscription Service. The listening adapter can receive this message from the messaging transport layer and update the database table based on which this Subscription Service is configured.
