Colleague Saul Caganoff has posted some great diagrams explaining the relative values of CEP (i.e. for operational intelligence) and BI (i.e. for longer-term business intelligence) on his blog. Note the conclusion – they are really complementary.
Indeed, I would go further and explain that BI data exploration (as typified by TIBCO Spotfire) is one type of manual BI, and Analytics are another (sometimes more automatable) type (as typified by TIBCO S+ and Miner) – which can identify or tune correlations and detections in the CEP rules (as typified by TIBCO BusinessEvents).
