result in step 6 and low load and high speed distributed analysis of the series data 101 fig7 depicts a method for data selection by the series data parallel analysis infrastructure 102 first a processing execution request from the user 106 is issued to the series data parallel analysis infrastructure 102 the processing execution request includes a sequential label range 303 and a series id 304 for the processing step 11 next information indicating data blocks 509 associated with the sequential label range 303 and the series id 304 included in the processing execution request is obtained from the distribution information management database 507 via the data search unit 505 step 12 data in the data blocks is transmitted to the distributed series data selection unit by ssh scp and so on via the data input output unit 506 and the data search unit 505 step 13 the data selection unit converts the data into a file tab separated text file or xml file for example or a form of data which can be transferred on memory to another program outside the series data parallel analysis infrastructure 102 and outputs the converted data to terminate the process step 14 in this way the data can be obtained without passing through the parallel processing infrastructure 104 fig8 depicts a method for recording data by the series.
