It is possible for your various systems to be integrated
with each other using a hub. The hub is implemented using an
Enterprise Application Integration (EAI) tool provided by a
third party vendor. Most hubs support HTTP and/or JMS and can
work with XML schemas or document type definitions (DTDs).
- XAI services are presented to the EAI tool as schemas or
as DTDs, immediately making the system callable from the
hub.
- Integration scripts or workflow processes are defined in
the EAI tools.
- At run time the hub uses HTTP or JMS to access the system
using inbound messages.
- Outgoing messages are used to notify the hub about events
occurring in the system. The messages are sent using HTTP or
JMS.
