One of the leading challenges for pervasive computing is to ease the application development to smoothly handle the surrounding envi- ronment. We consider the case where the environment produces heterogeneous and continuous data, e.g. temperature readings, car positions... We have defined a scenario for containers transporta- tion tracking in a medical context involving the transportation of fragile biological matter in sensor-enhanced containers. This sce- nario has been simulated as a testbed and offers a very nice setting to measure the agility of data-centric application development. On top of this scenario, we have built a pervasive application using a Pervasive Environment Management System called SoCQ (Ser- vice oriented Continuous Queries). SoCQ provides a data-oriented perspective of the pervasive environment, mixing classical data, streams and functionalities. For the demo, our objective is twofold: first, from the application developer point of view, she has access to the underlying SoCQ-schema and she may pose her own SQL-like queries to the simulated environment. Second, from the end-user point of view, she may quite easily interact with the environment either through a general dynamic visualization with Google Maps of hospitals, cars moving along roads and medical containers wait- ing or being transported, or by getting SMS notifications on her own phone of results of predefined queries.
