Advanced Queuing (AQ) is the message queuing functionality of the Oracle database that satisfies the above needs. Traditional message-oriented middleware address only a sub-set of these needs. Oracle AQ provides message queuing as an integrated part of the Oracle server. Oracle AQ provides this functionality by integrating the queuing system with the database itself AQ's integration with the database brings unprecedented levels of functionality, operational simplicity, security, reliability, availability, and scalability to the world of message queuing. In addition, AQ supports multiple communication channels, including the Internet, to cater to the needs of e-businesses. While using Oracle Advanced Queuing we do not have to install additional middle-ware dealing with inter-process communication and transaction monitoring. We can directly use an existing and well-known database and can benefit from given functionalities like online backup or transaction processing. Alternatively other simple and non-queue based messaging techniques can be used like the Java RMI, Or more complex approaches like CORBA.
