    Gesture-based navigation in graph databases - the kevin bacon game
    (Datenbanksysteme für Business, Technologie und Web (BTW) 2047, 2013) Beier, Felix; Baumann, Stephan; Betz, Heiko; Hagedorn, Stefan; Wagner, Timo
    Motion sensing devices like Microsoft's Kinect offer an alternative to traditional computer input devices like keyboards and mouses. Graph databases can naturally make use of gesture control as traversing graphs can easily be described by swiping or pointing gestures. In our demo we traverse the Internet Movie Database (IMDB) using a Kinect interface with the control logic in our data stream engine AnduIN. The gesture detection is done based on AnduIN's complex event processing functionality.

    Hibernating in the cloud - implementation and evaluation of Object-NoSQL-Mapping
    (Datenbanksysteme für Business, Technologie und Web (BTW) 2033, 2013) Wolf, Florian; Betz, Heiko; Gropengießer, Francis; Sattler, Kai-Uwe
    Object-relational mappers such as Hibernate are often used in applications to persist business objects in relational databases. The availability of commercial cloud-based database services opens new opportunities for developing and deploying database applications. In addition, highly scalable cloud services belong to the class of NoSQL systems promising to avoid the paradigm mismatch between the objectoriented programming model and the relational backend. In this paper, we discuss and analyze the usage of a scalable NoSQL solution such as Basho's RIAK as backend for Hibernate. We describe the necessary mapping and translation steps for an integration avoiding the detour on SQL. Finally, we present results of an experimental evaluation showing the benefits and limitations of this class of NoSQL backends for object-relational mappers.
