Answer / kriba
Queued Components, a key feature of COM+ and based on
Microsoft Message Queuing Services (MSMQ), provides an easy
way to invoke and execute components asynchronously.
Processing can occur without regard to the availability or
accessibility of either the sender or receiver. A home
shopping network is an example of the type of application
that might benefit from asynchronous processing. In this
asynchronous, disconnected scenario where viewers phone in
to several operators, orders are taken en masse and are
then queued for later retrieval and processing by the
server.
