The storage unit storage of the time -order data storage device of the embodiment method storage data data data data data data, where the data indicates the data that changes the time changes.Determine the data capacity of the data volume of the data that can be written to the storage unit and the full time of the interval function when the time -sequential data is measured from the external device that measured the timing of the timing data, and the full time of the timing data is measured.The first calculation unit is based on the interval function of the decision, and the interval is calculated. The interval represents the time required for all timing data of the statistical value data that constitutes the expectations of the external device.Based on the calculation of the interval of the calculation unit, the second computing unit has calculated the statistical values based on the entire timing data of the expected statistical value data described from the external device that constitutes the expected statistics data.The writing unit is written into the storage unit for the calculated statistics as the statistical value data.
Description
technical field [0001] Embodiments of the present invention relate to a time-series data storage device. Background technique [0002] In general, when data analysis is performed using a database that processes high speed but has a small capacity (for example, an in-memory database), data necessary for data analysis is input from another database with a large capacity and the analysis is performed. In this case, there is a problem that when analyzing data different from the data on which data analysis has been performed, data necessary for data analysis must be input again. [0003] Also, when accumulating data periodically measured by sensors (for example, meter data) in a capacity-limited database, the old data that has elapsed for a certain period of time is moved to another database (for example, low-speed but inexpensive magnetic tape device (tape) is processed. device)). In this case, when trying to refer to old data, there is a problem that the data must be restored...
