Abstract
The present invention is for shortening the time required to discover a phenomenon related to a detected event. Reverse reproduction is performed in data stream processing. Specifically, a computer systemprocesses multiple pieces of input datain accordance with times in chronological order denoted by the timestampswithin the input data, beginning from input dataincluding a timestamp (hereinafter, latest reference stamp) that denotes the newest time from among the timestamps denoting times prior to a reference time (for example, an event detection time). A method for creating output dataincluding the result of this processing and output timing are controlled on the basis of the lifetime of the input data, which is specified by a query. In accordance with this, the output data is properly outputted using reverse reproduction.
