Architecture

From Event Processing Wiki

At the most basic level, events occur which are of interest or not.

Events range from simple and seldom occuring, for example:

• solar eclipses
• earthquakes in Europe
• Total collapse of stock markets

to complex events which occur frequently, for example:

• probing dark pools for liquidity of complex derivative financial instruments.
• Position change of any letter or parcel distributed currently by US-Mail.
• A routing decision of a TCP/IP packet in a high throughput router

While it can be argued that it is possible to discern the order in which events occur, no practitioner would agree that a practical system should disregard the reality that systems distort that order.

Groups of events have some statistical characteristics (perhaps a bell shaped curve?) Interesting and profitable exploitation of those statistical characteristics is at the heart of event processing architecture.
