CEP is used in [[operational intelligence]] (OI) products to provide insight into business operations by running query analysis against live feeds and event data. OI collects real-time data and correlatecorrelates against historical data to provide insight and analysis. Multiple sources of data can be combined to provide a common operating picture that uses current information.
 
In [[network management]], [[systems management]], [[application management]] and [[service management]], people usually refer instead to [[event correlation]]. As CEP engines, event correlation engines (''event correlators'') analyze a mass of events, pinpoint the most significant ones, and trigger actions. However, most of them do not produce new inferred events. Instead, they relate high-level events with low-level events.<ref>J.P. Martin-Flatin, G. Jakobson and L.
