  • Data transmissions between two databases
    Patent number: 11768814
    Abstract: Disclosed herein are system, method, and computer program product embodiments for database management coordinators operated by a source server and a target server, respectively. The database management coordinator can be in a state selected from an initial state, a ready state, a transmission state, or a pause state. The database management coordinator operated by the source server can extract data in a first format stored in a first storage device and convert the data in the first format into a second format to be transmitted to the target serer. The database management coordinator operated by the target server can convert the data in the second format into a third format to be stored in a third storage device associated with the target server.
