DATA RETRIEVAL DEVICE, DATA RETRIEVAL METHOD AND PROGRAM, AND EDGE SERVER AND PROGRAM THEREOF

摘要

A system using edge computing is enabled to efficiently acquire data of an acquisition target without fail. A data search server KSV includes an industry information table 221 which stores an edge ID of an edge server operated and managed by a company/body, the edge ID being correlated with an industry ID which identifies an industry, and an ID of the company/body belonging to the industry. When a data acquisition request designating the industry ID is received from a user terminal, edge servers correlated with the designated industry ID are searched from the industry information table 221, and sensing data is acquired from the searched edge servers and transmitted to the user terminal of the source of the request. Menu screen information is sent from the data search server KSV to the user terminal, and displayed, and a user is enabled to select an industry on the menu screen.
