Document Type and Number:
WIPO Patent Application WO/2020/241207
Kind Code:
A1
Abstract:
A data management device (2000) is able to access a first storage region (50) and a first storage region (50). The first storage region (50) stores tree structure data (10). The tree structure data (10) has, as a node, a data set (20) which is a set of data (40). The second storage region (60) stores a data set (20) that is not included in the tree structure data (10). The data management device (2000) acquires data (40) that is to be inserted into a data set (20), and inserts the data (40) into the data set (20) already stored in the first storage region (50) or the second storage region (60), or generates a new data set (20) in the second storage region (60) and inserts the data (40) into that data set (20). In addition, the data management device (2000) inserts, into the tree structure data (10), one or more data sets (20) stored in the second storage region (60) if a prescribed condition is satisfied.
