The following figure shows the system assumed for these implementation examples.
Figure 2-14 Temperature analysis system assumed for the stream data processing implementation examples
In this temperature analysis system, observation sites 1 (ID: 1) and 2 (ID: 2) each monitor temperatures, and each send their observation results (in a file) to a sequential stream data processing system. The stream data processing system summarizes and analyzes the data that is sent by the observation sites as instructed by the queries, and then outputs the results to a file.
