Application Of Event-Driven Architecture In Implementation Of Financial Trade Clearing System

Modern information systems have been widely used in all walks of life, every moment has produced a large number of data. In this mass of data is behind a wealth of valuable information, necessary to have appropriate mechanisms and systems to discover and extract. Complex Event Processing (CEP) is an effective approach. It is an abstract from a lot of data out of the original incident and the events through a certain operator associated with the different events together to form composite event, said the new meaning, between the data reveal the hidden information. These events, in particular, is a compound event and quickly sent to the attention of its users or the system there, so that they can make decisions, improve business responsiveness, which is event-driven ideas. Event-driven architecture is a reactive system of abstraction, through the "push" model of event communication to provide concurrent reactive processing, particularly suitable for loosely coupled communication and support for sensing applications to address communication and coordination of loosely coupled SOA vision processing solution.This paper do the detailed analysis of the event-driven architecture than the traditional advantages of the system architecture, and describes the architecture can achieve this Apama complex event processing platform and its MonitorScript language. Then try to use them to design and implement a financial trading clearing system T and give a concrete description. Finally, existing complex event processing platform is lack of persistence ability, so we proposed two kinds of the common enhancements to achieve a resilient, sustainable-oriented event processing platform.
