TIME-SERIES DATA MANAGEMENT DEVICE, SYSTEM, METHOD, AND PROGRAM

摘要

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 having a feature value of a data series calculated at a specific regular time interval. In addition, a data search unit (130) makes a decision as to the feature value for each regular time interval included in the time-series index using an evaluation formula of a specified search condition, identifies a time period of a complying data series group, and performs a time-series analysis for only the data series of the identified time period.
