Enterprise Application Integration
Various independently running applications interchange data amongst themselves. COA (Control Office Application), which assists train controllers (despatchers) in planning and tracking the movement of trains across the Railway network, moves its data to various applications like NTES (National Train Inquiry System) through which passengers can obtain the trains' exact location as well as their movement forecast. Similarly train punctuality reports are generated through ICMS (Integrated Coaching Management System), which also receives data from COA.

—Talcott Parsons (1902–1979)
“The more specific idea of evolution now reached is—a change from an indefinite, incoherent homogeneity to a definite, coherent heterogeneity, accompanying the dissipation of motion and integration of matter.”
