Package oracle.jdbc.aq
This package is an Oracle JDBC extension that provides interfaces to access the Advanced Queuing feature of Oracle for enterprise messaging applications. JDBC AQ supports only the operational interfaces and not the administrative interface, but administrative operations can be accessed through embedded PL/SQL calls.
Enqueuing refers to sending a message to a queue and dequeuing refers to receiving one. A client application can create a message, set the desired properties on it and enqueue it by storing the message in the queue, a table in the database. When dequeuing a message, an application can either dequeue it synchronously by calling the dequeue method on the connection, or asynchronously by waiting for a notification from the database (see the registerAQNotification method on the database).
