Japanese Patent JPWO2021186737
Kind Code:
A1
Abstract:
An information management method executed by an information management apparatus that manages a space-time database which uses, as a key, a forward bit string of a bit string converted from space-time data including time data and positional data and which stores, as a value, corresponding data that corresponds to the space-time data, includes converting a range criterion of space-time data being a search object into a bit string, converting, when an index pattern of a first index that corresponds to a forward bit string of a bit string converted and an index pattern of a second index that corresponds to the key stored in the space-time database differ from each other, the first index into a third index of a same index pattern as the index pattern of the second index, and searching for the key using the third index and outputting, as a search result, corresponding data.
