Abstract:
A time series data base system, comprising:means for controlling to store data which stores time series data at an arbitrary sampling period &Dgr;T0 concerning an arbitrary object, stores time series data at a sampling period &Dgr;Ti (i is an integer of 1 or more) longer than the sampling period &Dgr;T0 concerning the object, repeatedly conducts an operation of storing the time series data at the sampling period &Dgr;Ti by at least one time or more, and stores the time series data at a plurality of sampling periods in a recording medium in a state that the time series data are hierarchically correlated; means for controlling to read out data which appropriately selects and reads time series data stored in said recording medium out of the time series data at the plurality of sampling periods upon a request of reading out the time series data; and means for displaying time series data which displays the read out time series data in a graph, wherein said means for controlling to read out data initially selects and reads out coarse data at a long sampling period which are coarsely displayed in said means for displaying and succeedingly selects and reads out dense data at a short sampling period which are densely displayed in comparison with the coarse data in said means for displaying, upon said request of reading out.
