Title: Database management system and database management method
Inventor: AKETO NAOYA
IPC: G06F11/14
Filed: 2020-03-30
Abstract: To provide a database management system (DBMS) capable of performing a consistent search, in which multiple nodes are included in multiple computers, each of which has multiple DBs and reflects the update of one DB to the remaining DBs.SOLUTION: The DBMS contains a first node and multiple second nodes. The first node manages the state of each second node. When the first DB of the first node is updated, the update will be reflected in the second DB of each second node. The first node changes the state of each of a certain number of second nodes to "stop searching" (search TX cannot be accepted). When each of the certain number of second nodes does not execute the search TX, the reference destination is updated to the second DB data, and the first node changes the state of the second node to "normal" (search TX accepted). When the first node accepts a search TX, the search TX is assigned to the "normal" second node.SELECTED DRAWING: Figure 1
