This illustration shows four databases in a directed networks configuration. The first database is a source database in Hong Kong which propagates messages to a queue in an intermediate database in Chicago.

The intermediate database in Chicago propagates messages that originated at the source database in Hong Kong to a queue in a database in New York and to a queue in a database in Miami.

The intermediate database in Chicago is:

• Destination queue for the source queue in Hong Kong

• Source queue for the destination queues in New York and Miami
