Processing nested complex sequence pattern queries over event streams
2010
Proceedings of the Seventh International Workshop on Data Management for Sensor Networks - DMSN '10
Preserved Fulltext
These monitoring applications submit complex event queries to track sequences of events that match a given pattern. ...
As these systems mature the need for increasingly complex nested sequence queries arises, while the state-of-the-art CEP systems mostly focus on the execution of flat sequence queries only. ...
The Nested Complex Pattern Query Language NEEL We now briefly introduce the NEEL query language for specifying complex nested event pattern queries [1, 6, 9] as an extension of basic non-nested languages ...
