EVENT PROCESSING METHOD USING HIERARCHICAL STRUCTURE AND EVENT PROCESSING ENGINE AND SYSTEM THEREOF

PURPOSE: An event processing method using a hierarchy structure, an event processing engine, and a system are provided to reuse an intermediate operation value, which is generated in an event process, thereby extracting meaningful data from an event determination and transmission result. CONSTITUTION: When data is generated in a data source system, an event sensor unit(110) senses the data as an event. An event processing engine(120) generates an action plan by processing the data as the event corresponding to defined contents. An event action unit(130) transmits an event processing result which is comprised in a content processor(123) and corresponds to an event definition. An event monitor unit(140) performs real time monitoring, event monitoring, sensor monitoring, queue monitoring, and processing situation monitoring of various situations. An event control unit(150) manages information necessary for executing an event processor.
