Management of Dynamic Context Models with Data Stream Processing -
Prof. Dr. Daniela Nicklas

With the upcoming widespread availability of sensors, more and more applications depend on physical phenomena. Up-to-date real world information is embedded into business processes, in production environments, or in mobile applications, so that such context-aware applications can adapt their behavior to the current situation of their user or environment. For this, a high variety of so-called context information has to be managed, often in an push-based way (applications register for context changes). In more and more applications, the amount, the physical source distribution, the resources of the processing devices, and/or the update rate of the incoming sensor data prevents its storage in DBMS and the use of triggers or periodic queries. This talk shows how data stream management techniques can be used to provide an efficient, comprehensive, up-to-date, and even quality-annotated dynamic context model for mobile applications.


Daniela Nicklas is a Junior Professor for Database and Internet technologies at the Carl von Ossietzky Universit├Ąt Oldenburg since 2008. Besides her research on context-aware applications and context modeling, she works on data stream processing and sensor-based systems within the application domains of transportation, energy, and ambient environments.
She received her PhD (Dr. rer. nat.) in Computer Science 2008 from the University of Stuttgart, working within the Center of Collaboration (SFB 627) "Nexus" under the supervision of Prof. Dr. Bernhard Mitschang. The main contribution if her thesis was architecture and a spatial data model for large-scale integration of context data for location-based, mobile applications. After that, she worked for two years as PostDoc in that Center of Project, co-leading a project on context-aware workflows together with Prof. Dr. Frank Leymann.
In 2008, she received an IBM Exploratory Stream Analytics Innovation award for "Data Stream Technology for Future Energy Grid Control". Besides being a committee member in many programme committees of pervasive computing and database conferences and workshops, she helped organizing international conference, like e.g., the Annual IEEE International Conferences on Pervasive Computing and Communications (PerCom) as Vice Program Chair in 2010. She is also a member of the editorial boards of the Elsevier Pervasive Computing and Communication Journal, the International Journal of Pervasive Computing and Communications (Emerald), and the Datenbankspektrum (German Journal on Databases).
