Information processing device, information processing method, and computer program product

An information processing method implemented to make an information processing device store data, the information processing device including

• a first memory unit configured to store therein data having a graph structure which contains, as node information of a node, a list of edges related to the node, and
• a second memory unit configured to store therein data which has a non-graph structure different from the graph structure and which represents a mutual relationship between data elements,
• the method comprising:
• transforming a data structure of the data stored in the first memory unit from the graph structure to the non-graph structure;
• and
• storing data, which has the data structure transformed from the graph structure to the non-graph structure, in the second memory unit.

A computer program product comprising a computer-readable medium containing an information processing program that makes an information processing device store data, the device including

• a first memory unit configured to store therein data having a graph structure which contains, as node information of a node, a list of edges related to the node, and
• a second memory unit configured to store therein data which has a non-graph structure different from the graph structure and which represents a mutual relationship between data elements,
• wherein the information processing program, when executed by a computer causes the computer to execute:
• transforming a data structure of the data stored in the first memory unit from the graph structure to the non-graph structure;
• and
• storing data, which has the data structure transformed from the graph structure to the non-graph structure, in the second memory unit.
