INFORMATION PROCESSING DEVICE, INFORMATION PROVIDING DEVICE, INFORMATION SYSTEM, AND COMPUTER PROGRAM PRODUCT

摘要

An example information processing device includes a first memory that can store graph data indicating at least either nodes or edges constituting a graph and a second memory that can store graph data at an access speed faster than an access speed of the first memory. An obtaining unit obtains relational data containing relationships that can be converted into at least one graph. A determining unit determines whether to store certain graph data in the first or second memory, based on at least any of specification information specifying a storage destination for the certain graph data, or relations of connection with respect to the graph data stored in the first or second memory, and a data size of the relational data. A memory controller stores the certain graph data in the first or second memory based on the determination.
