Pervasive systems give an overview of what digital environments should look like in the future. SoCQ takes a data-oriented perspective on the pervasive environment through a unified view of available data and services. Pervasive applications can then be created in a declarative fashion using service-oriented continuous queries. We tackle the following challenges: 1) a homogeneous representation for data sources and services from the pervasive environment, 2) a query language over pervasive environments, 3) a Pervasive Environment Management System (PEMS). This demonstration shows our PEMS prototype in action, allowing the user to visualize the environment and define pervasive applications.
