Patent ID: 8095690

Claim:
A machine-readable medium for storing a stream data processing program for receiving, as primary information, stream data input to a computer comprising a processor and a storage system, creating secondary information by obtaining a given period of the received primary information as a processing target, and generating time control information indicating advance of time in addition to the primary information, wherein the stream data processing program controls the computer to execute the procedures of: receiving the input stream data as the primary information; calculating, by a time control information generation module for generating, as the time control information, time information at a time of reception of the primary information, a time at which the time control information is generated as a next ignition time, and storing the next ignition time in a next ignition time holding area, which is set in the storage system; generating the time control information when current time information reaches the next ignition time held in the next ignition time holding area; and creating, upon reception of the generated time control information, secondary information by obtaining the given period of the received primary information as the processing target.
