A stream data processing server for processing stream data comprising a stream data processing module for cutting the plurality of pieces of data that are included within a processing range as a target out of the stream data by using a sliding window, and executing analyzing processing for the cut out plurality of pieces of data, the stream data processing module having an approximate expression; the approximate expression calculating module being configured to: determine one of the time stamps of the cut out plurality of pieces of data as a time origin; modify the time stamps of the cut out plurality of pieces of data to relative time values in relation to the determined time origin; and use the modified time stamps and the values of the plurality of pieces of data to calculate the approximate expression. |
