  13. 13. Key Elements of Connected Intelligence Always-on devices connected to variety of sensors and running multiple software applications 1 High-frequency data analysis for instant decision making and automation of information flows 2 Maximizing value from hi-velocity data in real time 3 Fast Data Real-Time Analytics Intelligent Devices
  14. 14. The value of data decreases over time Ensuring Real-Time Accuracy, Efficiency, and Scale Business event Action Time Business Value Data captured Analysis completed Action taken Source: Richard Hackethorn’s Component’s of Action Time
  15. 15. Complex Event Processing - CEP Method of tracking and analyzing data combined from multiple streams to infer events or patterns that suggest more complicated circumstances. Goal is to identify business meaning of events (such as opportunities or threats) and respond to them as quickly as possible. Source: Event Patterns Event Stream Fine-grained simple events from sensors and edge devices Complex Events Machine module non- functional, power outage, device tampering, etc.
  16. 16. Complex Event Processing •Filtering –New stream filtered for specific criteria, e.g. temperature > 200 F •Correlation & Aggregation –Scrolling, time-based window metrics, e.g. average heart pulse rate in the last 3 days •Pattern Matching –Notification of detected event patterns, e.g. machine events A, B and C occurred within 15 minute window •Geospatial, Predictive Modeling and beyond –Immediate recognition of geographical movement patterns, apply historical business intelligence models using data mining algorithms Event Patterns Event Patterns Complex Events Machine module non- functional, power outage, device tampering, etc. Event Stream Fine-grained simple events from sensors and edge devices
  17. 17. CEP Engine Query Query Oracle Event Processing Embedded OEP-E: High-Level Architecture Input Adapters Output Adapters event event event Real-time event data Context-aware filtering, correlation, aggregation and processing of data Processed business events for downstream applications event event event Sensors Backend Applications
  18. 18. Continuous Query Language - CQL •CQL is based on standard SQL with extensions for streaming data –CQL queries support filtering, partitioning, aggregation, correlation (joins across streams), and pattern matching on streaming and relational data –Extends standard SQL by adding notion of Stream, operators for mapping between relations and streams, and extensions for pattern matching –Window operator (e.g. RANGE 1 MINUTE) transforms stream into a relation •Example: –SELECT AVG(temperature) AS avgTemp, tempSensorId FROM temperatureInputStream [RANGE 1 MINUTE] GROUP BY tempSensorId
  19. 19. Efficient Handling of Streaming Data Flow Event Processing Network (EPN) Example
