Abstract
An event notification matching system, including an event matching table forming a plurality of nodes. Each node is assigned a subscriber request value and contains identifiers for one or more subscribers to be notified at the occurrence of an event relating to the subscriber request value. The event notification matching system may also include a table index. The table index receives input values from an event processing module and selects one or more of the nodes that have subscriber request values corresponding to the received input values. The event processor receives event data from a predetermined source, and formats the input values to simplify the operations performed by the event matching table. The event notification matching system is configured such that the event data need not be compared to non-matching nodes in the event matching table.
