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 correlates 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. Lewis, "Event Correlation in Integrated Management: Lessons Learned and Outlook", Journal of Network and Systems Management, Vol. 17, No. 4, December 2007.</ref>

[[Inference engine]]s, e.g., [[rule-based system|rule-based reasoning engine]]s, typically produce inferred information in [[artificial intelligence]]. However, they do not usually produce new information in the form of complex (i.e., inferred) events.
