AIMS: A tool for the view-based analysis of streams of flight data

The Airspace Monitoring System (AIMS) monitors and analyzes flight data streams with respect to the occurrence of arbitrary, freely definable complex events. In contrast to already existing tools which often focus on a single task like flight delay detection, AIMS represents a general approach to a comprehensive analysis of aircraft movements, serving as an exemplary study for many similar scenarios in data stream management. In order to develop a flexible and extensible monitoring system, SQL views are employed for analyzing flight movements in a declarative way. Their definition can be easily modified, so that new anomalies can simply be defined in form of view hierarchies. The key innovative feature of AIMS is the implementation of a stream processing environment within a traditional DBMS for continuously evaluating anomaly detection queries over rapidly changing sensor data.
