Method and system for ensuring system awareness with data base connection on demand

摘要

A method and system for establishing a situation for use in an event-driven application receives one or more events, and queries an external database for obtaining auxiliary data defining relevant external knowledge for detecting the situation. The event or events are integrated with the auxiliary data for generating a composite event defining the situation. The database query is constructed in real time based on the received events with a query language using SQL primitives.
