The goal of this study is the investigation (evaluation) of Data Stream Management System (DSMS) engines for the purpose of real-world applications. The main diffences of existing engines are to be identified and described. The feasibility for particular application scenarios shall be named. The emphasis is on restrictions and the potential for adaptation with respect to the following aspects:
In a second part, the study should describe for a smaller number of engines the actual implementation of a given scenario. This scenario is a simple version of airport vehicle tracking, with warnings to be issued when one of the vehicles enters a forbidden area. A demonstration is to be built with two diffent engines that uses some artificial input data and shows the execution of several queries.
