Data search apparatus, and data search method and program thereof, and edge server and program thereof

An edge server which is a specific edge server of a plurality of edge servers capable of receiving and accumulating data transmitted from a plurality of devices and capable of executing data transmission among the edge servers, the edge server comprising:

• a storage table configured to correlate and store information which identifies the edge servers, and information which identifies an organization to which an owner of the devices which transmit the data to the edge servers belongs;
• a data search operation support part configured to transmit support information of a data search operation to a terminal functioning as a data acquisition side, and to receive a data acquisition request including identification information of an organization that is a data acquisition target, the data acquisition request being transmitted from the terminal functioning as the data acquisition side in accordance with the support information;
• an edge server search part configured to search, from the storage table, identification information of an edge server which is correlated with the identification information of the organization included in the received data acquisition request;
• a data collection part configured to collect, based on the searched identification information of the edge server, the accumulated data from the corresponding edge server;
• and
• a data transmission part configured to transmit via a network the collected data to the terminal which is a transmission source of the data acquisition request.

A non-transitory computer readable medium storing a program causing a computer to execute a data search method, the computer being included in a data search apparatus connectable via a network to a plurality of edge servers functioning as a data provision side and to a terminal functioning as a data acquisition side, the edge servers being configured to receive and accumulate data transmitted form a plurality of devices, the data search method comprising:

• correlating, and storing in a storage table, information which identifies the edge servers, and information which identifies an organization to which an owner of the devices which transmit the data to the edge servers belongs;
• transmitting support information of a data search operation to the terminal functioning as the data acquisition side, and receiving a data acquisition request including identification information of an organization that is a data acquisition target, the data acquisition request being transmitted from the terminal functioning as the data acquisition side in accordance with the support information;
• searching, when receiving a data acquisition request including the identification information of the organization from the terminal functioning as the data acquisition side, identification information of an edge server, which is correlated with the identification information of the organization included in the data acquisition request, from the storage table;
• collecting, based on the searched identification information of the edge server, the accumulated data from the corresponding edge server;
• and
• transmitting via the network the collected data to the terminal which is a transmission source of the data acquisition request.
