Different scenarios from market verticals such as manufacturing, oil and gas, utilities, financial services, health care, web analytics, and IT monitoring can profit from the opportunity to make more informed business decisions in near real-time based on the ability to monitor, analyze and act on the data in motion. These applications, typically event-driven and characterized by high input data rates, continuous analytics, and millisecond latency requirements, introduce a number of challenges to traditional Database Management Systems (DBMS). This is pushing many organizations to start adopting Data Stream Management Systems (DSMS), middleware systems that incrementally process long-running continuous queries over temporal data streams. Modern DSMS typically provide Complex Event Processing (CEP) techniques to identify meaningful patterns, relationships and data abstractions from among seemingly unrelated events, triggering immediate response actions. An example of a commercial DSMS is Microsoft StreamInsight, a platform for developing and deploying streaming applications which leverages a well-defined temporal stream model and algebra. This talk, besides providing an overall introduction to CEP, will present scenarios where its adoption is gaining momentum, provide a quick overview of existing research and commercial CEP platforms (including a more extended overview of Microsoft StreamInsight) and finally discuss some future trends and challenges for CEP.
