DATA CONFIGURATION METHOD AND DEVICE, AND ROLLBACK METHOD AND DEVICE FOR DATA CONFIGURATION

A data configuration method and device, and a data configuration rollback method and device are applied to the field of information processing technologies. The data configuration method includes: receiving a data configuration operation request, where the data configuration operation request includes an data insert request, a data delete request, or an data update request; allocating an operation serial number to the data configuration operation request; and recording the allocated operation serial number and data requested to be operated by the data configuration operation request, as a mapping relationship between a creation operation serial number, a deletion operation serial number, and the data according to the data configuration operation request. The data configuration rollback method includes: obtaining a rollback operation serial number of a data configuration; and obtaining, according to a recorded mapping relationship between a creation operation serial number, a deletion operation serial number, and data, data corresponding to a creation operation serial number that is smaller than or equal to (or greater than or equal to) the rollback operation serial number and a deletion operation serial number that is greater than (or smaller than) the rollback operation serial number or a deletion operation serial number that is null. The data configuration operation and data configuration rollback are implemented.
