Abstract:
Disclosed is a time-series management device capable of filtering time-series data having a possibility of matching a specified search pattern and reading in the data from a storage device when performing a time-series analysis. A data accumulation unit (120) creates a time-series index wherein feature values of a data series have been calculated at specific regular time intervals. In addition, a data search unit (130) assesses the feature values for each regular time interval included in the time-series index using an evaluation formula of specified search conditions, identifies the time period of a complying data series group, and performs time-series analysis for only the data series of the identified time period.
