Abstract
A database management system according to one embodiment includes at least one processor configured to control a hierarchical database including a plurality of end databases and a primary database directly or indirectly connected to the plurality of end databases. Each of the plurality of end databases stores sensor data. The primary database provides a virtual data table. The at least one processor transmits, to the end database, a search instruction for obtaining a result set containing a combination of an intermediate result based on the sensor data and a path ID for uniquely identifying a path connecting the primary database and the end database, receives a result set, and represents a search result based on the result set by the virtual data table and outputs the search result.
