Stream Processing Environmental Applications in Jordan Valley

Database system architectures have been gone through innovative changes, specially theunifications of algorithms and data via the integration of programming languages with thedatabase system. Such an innovative changes is needed in Stream-based applications since theyhave different requirements for the principal of stream data processing system. For example, themonitoring component requires query processing system to detect user-defined events in a timelymanner as in real time monitoring system. Furthermore, stream processing fits a large class ofnew applications for which conventional DBMSs fall short since many stream-oriented systemsare inherently geographically distributed and the distribution offers a scalable load managementand higher availability.This paper presents statistical information about metrological data such as the weather, soil andevapotranspiration as collected by the weather stations distributed in different locations in JordanValley. In addition, it shows the importance of Stream Processing in some real life applications,and shows how the database systems can help researcher in building prototypes that can beimplemented and used in a continuous monitoring system.
