When to Send Messages Between Databases

As organizations grow, they typically develop a variety of applications to automate processes and manage tasks. Although these applications do not share data directly, they might not operate entirely autonomously. These applications need a way to communicate with one another to coordinate tasks and exchange information.

Using Oracle Streams Advanced Queuing (AQ), applications can securely and reliably communicate with one another in an asynchronous manner. Oracle Streams AQ supports all of the standard features of message queuing systems, including multiconsumer queues, publish and subscribe, content-based routing, Internet propagation, and transformations. So, for example, the shipping department can easily notify the billing department when a product has shipped, and the customer can be billed accordingly.

By combining Oracle Streams AQ with the appropriate messaging gateway, applications can even interoperate with other message queuing systems, such as TIBCO Rendezvous or IBM Websphere MQ. This ability can be especially useful when it is necessary to share information with business partners or customers.
