Integration Broker is what?
Enables disparate systems to share
information in common manner.
 The central control and storage point that
mediates events to and from applications,
managing the essential queuing, routing,
filtering and storing of information in an
reliable and secure manner.

Chosen because…
– Features
– Cost

Name is misleading…
– It is an Integration Broker
– The “web” part of the name makes people think
it’s only for web access… untrue.
What can it do?

Just a few examples
– Notice changes to PS data and apply the
changes to the directory or student data
– Notice changes to the directory data and apply
the changes to PS or student
– Notice data changes to any table or field in an
Oracle or Informix database and publish events
– Notice changes in flat files and process as
appropriate
Goals
When data is altered in our PeopleSoft
system populate those changes to the
Directory, without any changes to the
PeopleSoft applications or the Directory
software.
 Same for Student System.
 Provide an infrastructure to allow these
types of interactions between other systems

Event Driven

Event driven
– Integrations are built by a developer
– When an event happens a process is triggered
within the Broker
– The process determines what happens, how
data is transformed and moved from one place
to another
– Two phase commit is not available, must use a
compensating transactions if back-out is desired

Broker

The Enterprise Server Broker is the main
engine
– Message repository when using guaranteed
delivery
– Data transformation
– Event handling
– Publish and subscribe
– Synchronous messaging
– “Near real time” updating
Adapters

Adapters are configured to interface with
our infrastructure

Student (via CUSSP)

Issues
Where is the starting point(data of record)?
 What does the business process require to
be done?
 Should a workflow process be triggered on
the event completion of XXX?
 This is all new tools but yet old problems.
 WE HAVE THE TECHNOLOGY !!
