Patent US10225078


Issued 2019-03-05

Managing A Database Management System Using A Blockchain Database

Disclosed aspects relate to managing a database management system (DBMS). A central database to include a set of central data may be structured with respect to the DBMS. A blockchain database which is linked with the central database may be constructed with respect to the DBMS. A set of blockchain data may be established in the blockchain database corresponding to the set of central data of the central database. An access request may be received with respect to the DBMS. In response to receiving the access request, both the central database and the blockchain database may be maintained.

3 Independent Claims

  • 1. A computer-implemented method for managing a database management system (DBMS), the method comprising: structuring, with respect to the DBMS, a central database to include a set of central data; constructing, with respect to the DBMS, a blockchain database which is linked with the central database; establishing, in the blockchain database corresponding to the set of central data of the central database, a set of blockchain data; receiving, with respect to the DBMS, an access request; maintaining, in response to receiving the access request, both the central database and the blockchain databases; determining a mismatch of a first central entry of the central database and a first blockchain entry of the blockchain database, wherein the mismatch is based on a magnitude of discrepancy with respect to a threshold similarity factor; and recording, in a blockchain permanent log, the mismatch of the first central entry of the central database and the first blockchain entry of the blockchain database.

  • 19. A system for managing a database management system (DBMS), the system comprising: a memory having a set of computer readable computer instructions, and a processor for executing the set of computer readable instructions, the set of computer readable instructions including: structuring, with respect to the DBMS, a central database to include a set of central data; constructing, with respect to the DBMS, a blockchain database which is linked with the central database; establishing, in the blockchain database corresponding to the set of central data of the central database, a set of blockchain data; receiving, with respect to the DBMS, an access request; maintaining, in response to receiving the access request, both the central database and the blockchain databases; determining, a mismatch of a first central entry of the central database and a first blockchain entry of the blockchain database, wherein the mismatch is based on a magnitude of discrepancy with respect to a threshold similarity factor; and recording, in a blockchain permanent log, the mismatch of the first central entry of the central database and the first blockchain entry of the blockchain database.

  • 20. A computer program product for managing a database management system (DBMS), the computer program product comprising a computer readable storage medium having program instructions embodied therewith, wherein the computer readable storage medium is not a transitory signal per se, the program instructions executable by a processor to cause the processor to perform a method comprising: structuring, with respect to the DBMS, a central database to include a set of central data; constructing, with respect to the DBMS, a blockchain database which is linked with the central database; establishing, in the blockchain database corresponding to the set of central data of the central database, a set of blockchain data; receiving, with respect to the DBMS, an access request; maintaining, in response to receiving the access request, both the central database and the blockchain databases; determining a mismatch of a first central entry of the central database and a first blockchain entry of the blockchain database, wherein the mismatch is based on a magnitude of discrepancy with respect to a threshold similarity factor; and recording, in a blockchain permanent log, the mismatch of the first central entry of the central database and the first blockchain entry of the blockchain database.
