Data Transmission Method, Electronic Device, and Computer Readable Storage Medium

An electronic device, comprising a memory, a processor, and executable instructions stored in the memory to be executed by the processor, wherein in response to the processor executing the instructions, the electronic device is to perform the method comprising:

• receiving a first event from a second electronic device, wherein the first event comprises first database version information, the first database version information describes a database version of a second source database, and the second source database is a local database of the second electronic device;
• creating a first empty mapping database of a first source database based on the first database version information, wherein the first source database is a local database of the electronic device;
• virtualizing the first source database and the first empty mapping database to obtain a first virtual database;
• performing data mapping in the first virtual database to map data in the first source database to the first empty mapping database, to obtain a first database in which data mapping is completed;
• obtaining a first mapping database based on the first database;
• and
• sending the first mapping database to the second electronic device.

A non-transitory computer-readable storage medium, wherein the computer-readable storage medium stores executable instructions therein, and in response to the executable instructions being executed by a processor of a second electronic device, the second electronic device is to perform the method comprising:

• receiving a first event from a first electronic device, wherein the first event comprises first database version information, the first database version information describes a database version of a second source database, and the second source database is a local database of the first electronic device;
• creating a first empty mapping database of a first source database based on the first database version information, wherein the first source database is a local database of the second electronic device;
• virtualizing the first source database and the first empty mapping database to obtain a first virtual database;
• performing data mapping in the first virtual database to map data in the first source database to the first empty mapping database, to obtain a first database in which data mapping is completed;
• obtaining a first mapping database based on the first database;
• and
• sending the first mapping database to the second electronic device.
