Data transmissions between two databases

A system for a target server, comprising:

• a first storage device to store data in a first format;
• a second storage device to store the data in a second format;
• at least one processor coupled to the first storage device and the second storage device;
• and
• a database management coordinator operated by the at least one processor to be in a state selected from an initial state, a ready state, a transmission state, or a pause state, wherein when the database management coordinator is in the transmission state, the database management coordinator is configured to:
• receive the data in the first format from a source server and store the data in the first format into the first storage device;
• convert the data in the first format into the second format;
• and
• store the data in the second format in the second storage device, wherein the data in the second format is converted by the source server from a third format stored in a third storage device associated with the source server to the first format before transmitting to the target server, the first format includes a message header of a message containing the data received from the source server, and wherein the second format is different from the first format and the third format.

A non-transitory computer-readable medium having instructions stored thereon that, when executed by at least one computing device, cause the at least one computing device to perform operations comprising:

• determining, by a database management coordinator operated by the at least one computing device, to be in a state selected from an initial state, a ready state, a transmission state, or a pause state;
• extracting, managed by the database management coordinator, data in a first format stored in a first storage device, wherein the extracting the data in the first format includes reading data in the first format in the first storage device, converting the data in the first format into a second format, and storing the data in the second format in a second storage device;
• and
• transmitting, when the database management coordinator is in the transmission state, the data in the second format stored in the second storage device to a target server, wherein the second format includes a message header of a message containing the data to be transmitted from the source server to the target server, and the data is received by the target server in the second format to be converted into a third format different from the first format and the second format.
