TIME SERIES DATA MANAGEMENT METHOD AND TIME SERIES DATA MANAGEMENT SYSTEM

摘要

A time-series data management method for generating a histogram from time-series data using a computer provided with a processor and a storage device, the computer storing the time-series data including a time of day and a value in the storage device, storing section information including a start time, an end time, and an identifier of the time-series data in the storage device, generating the histogram from the time-series data corresponding to the section information and storing the generated histogram in the storage device, accepting a section to be searched and selecting the histogram associated with the section to be searched, and combining the selected histograms and generating a histogram for the section to be searched

1. A time series data management method by which a histogram is generated from time series data in a computer that includes a processor and a storage device, the method comprising:
a first step in which the computer stores in the storage device the time series data including a time and a value; a second step in which the computer stores in the storage device interval information including a start time, an end time, and an identifier of the time series data; a third step in which the computer generates the histogram from the time series data corresponding to the interval information and accumulates the histogram in the storage device; a fourth step in which the computer receives an interval to be searched; and a fifth step in which the computer selects the histograms relating to the interval to be searched, combines the selected histograms, and generates a histogram of the interval to be searched.
