Contents Intro.

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. Another example are so-called SCADA systems (supervisory control and data acquisition), where complex installations (e.g., energy grids or power plants) are monitored and controlled. In general, data can be managed either by a database management system (DBMS), or directly by the application. The first approach has many advantages: information demands can be declared by queries and kept separately from the application. When the information demand changes, only the query has to be changed (which dramatically decreases software maintenance costs). In addition, a DBMS can optimize the query execution, so that the requested data is retrieved efficiently from the
