SPATIO-TEMPORAL DATA MANAGEMENT SYSTEM, SPATIO-TEMPORAL DATA MANAGEMENT METHOD, AND PROGRAM THEREOF
First Claim
1. A spatio-temporal data management system for managing time series data associated with a spatio-temporal region, comprising:
- a processor for executing a program;
a memory for storing the program; and
a storage device for storing the time series data,wherein the processor is configured to;
segment the spatio-temporal region in time and space to generate a plurality of spatio-temporal segments;
assign, in consideration of temporal and spatial proximity of the plurality of spatio-temporal segments, identifiers for uniquely identifying the plurality of spatio-temporal segments, each of the identifiers being expressed with a one-dimensional integer value; and
determine an arrangement of the time series data so that pieces of data of spatio-temporal segments that are close in the assigned identifiers are arranged close on the storage device.

Abstract
It is provided a spatio-temporal data management system for managing time series data associated with a spatio-temporal region, comprising: a processor for executing a program; a memory for storing the program; and a storage device for storing the time series data. The processor segments the spatio-temporal region in time and space to generate a plurality of spatio-temporal segments, assigns, in consideration of temporal and spatial proximity of the plurality of spatio-temporal segments, identifiers for uniquely identifying the plurality of spatio-temporal segments, each of the identifiers being expressed with a one-dimensional integer value; and determines an arrangement of the time series data so that pieces of data of spatio-temporal segments that are close in the assigned identifiers are arranged close on the storage device.

8. A spatio-temporal data management method to be executed by a computer system for managing time series data associated with a spatio-temporal region,
the computer system including a processor for executing a program, a memory for storing the program, and a storage device for storing the time series data, the spatio-temporal data management method including steps of: -
segmenting, by the processor, the spatio-temporal region in time and space to generate a plurality of spatio-temporal segments; assigning, by the processor, in consideration of temporal and spatial proximity of the plurality of spatio-temporal segments, identifiers for uniquely identifying the plurality of spatio-temporal segments, each of the identifiers being expressed with a one-dimensional integer value; and determining, by the processor, an arrangement of the time series data so that pieces of data of spatio-temporal segments that are close in the assigned identifiers are arranged close on the storage device. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A non-transitory machine-readable storage medium, containing at least one sequence of instructions for controlling a computer system for managing time series data associated with a spatio-temporal region,
the computer system including a processor for executing a program, a memory for storing the program, and a storage device for storing the time series data, the instructions that, when executed, causes the computer system to execute: -
segment the spatio-temporal region in time and space to generate a plurality of spatio-temporal segments; assigne, in consideration of temporal and spatial proximity of the plurality of spatio-temporal segments, identifiers for uniquely identifying the plurality of spatio-temporal segments, each of the identifiers being expressed with a one-dimensional integer value; and determine an arrangement of the time series data so that pieces of data of spatio-temporal segments that are close in the assigned identifiers are arranged close on the storage device.
