Extreme transaction processing (XTP) is being added to complex event
processing (CEP) in service-oriented architecture (SOA) implementations
for the financial services industry, explains David Chappell, vice
president and chief technologist for SOA at Oracle Corp. Chappell:
"What we're seeing is that SOA coupled with a class of applications
coined as extreme transaction processing or XTP is the future for
financial services infrastructure. So IT continues to be seen as the
enabler. We've seen some supporting data from Gartner/DataQuest that
IT spending in financial services is going to reach $566 billion by
2010. Where SOA comes into the picture is that it enables IT to deliver
new business services faster, while leveraging existing systems. At
the same time the financial institutions are pushing limits that require
more processing capability yet at the same time they don't want to see
an exponential rise in their investment in hardware. So the extreme
transaction processing class of applications has been most notably seen
in areas such as fraud detection, risk computation and stock trade
resolution... What XTP does is allow transactions to occur in memory
and not against the backend systems directly due to the need for extremely
fast response rates, but still including transactional integrity. So
think of classes of applications that need to handle large volumes of
data that need to be absorbed, correlated and acted upon. Typically
that data processed by XTP applications comes in the form of large
numbers of events and usually represents data that changes frequently...
once the pattern matching engine, whether it's built directly into the
XTP application itself or is identified by the complex event processing
engine, is it identifies an event of significance such as ATM withdrawal
fraud. Say for example your ATM card is used in different ATM machines
or is used to make purchases in three or four states or even different
countries within a matter of minutes, that's usually a flag that some
kind of fraud is going on. Once that kind of a situation is detected
then an SOA process in BPEL can be kicked off to make the proper
notification, send alerts to Business Activity Monitoring dashboards...
