Real-time event driven architecture for activity monitoring and early warning

There is an increasing demand outside of the military and intelligence community for real-time and near real-time applications and solutions, especially in areas where continuous adaptation to the environment is critical. In this paper, we survey the recent evolution of the event driven applications and discuss their potential implications on the system and middleware trends. These applications include service provisioning for telecommunication, trading system for financial services, logistics and asset management in manufacturing, digital oil field for the production of oil and gas, telematics for automotive maintenance, and disease surveillance for public health. These applications likely drive the emergence of a new class of middleware components and system architectures that are optimized for event processing and routing. At the system level, event processing drives the convergence of message gateways and routers. At the middleware level, event based application necessitates the emergence of programmable event processing engine to compliment traditional database management systems and application servers.
