Details Procedure To Generate Graph in Project 2011

To generates the graph using the input tuples that arrive from different weather stations. The graphs are plotted for both traditional algorithm and adaptive join algorithm. The tuples provides the informations like weather station name, measurements like air temperature, dew point temperature and relative humidity which is plotted against the time period to compare the weather in distinct stations.The graphs are generated as images which can be saved for future references using the GD plugins of Hypertext Preprocessor (PHP). In traditional algorithms the join results are not produced until the whole relations are received. So the graphs are plotted after the traditional algorithm produce join results. But, in adaptive join algorithms the graphs are plotted as soon as the first input tuples arrive and thus masks theetworks delay.
