Following the example of sensor data from this section, suppose that the following temperature-time readings are generated by sensor 100, and each arrives at the DSMS at the time generated: (80,0), (70,50), (60,70), (65,100). Times are in minutes. If R is the query of Fig. 23.11, W hat are the tuples of Istream (.R) and Dstream(f?), and at what time is each of these tuples generated?
