Complex Event Processing (CEP) is the state-of-the-art technology for continuously monitoring and analyzing streams of events. One of the key features of CEP is to support pattern matching queries to detect user-defined sequences of predicates on event streams. However, due to the vast amount of parameters, tweaking the queries to deliver the desired results is challenging. For this demonstration, we connected a database-backed CEP system (Jepc, ChronicleDB) with a scientific toolbox for interactive data exploration and geo visualization (Vat System), and thus allow users to interactively explore event data via CEP queries. Furthermore, the pairing of these systems allows to combine the results of event queries with additional non-relational data-sets such as raster data, leading to insights beyond pure event-based analytics. In this demonstration, we showcase the first promising results of this combination by evaluating three use cases involving high-volume event data collected from aircrafts in-flight.
