There has been significant event processing controversy in the use of the terms event stream processing (ESP) and complex event processing (CEP). CEP was originally envisioned as a technology to extract new information from message-based systems; while ESP was designed to extract new information from database-oriented systems. One school of thought is that ESP is analogous to signal processing and CEP is more aligned with higher level situational inferencing. Another school of thought is that CEP and ESP are one in the same!
