<p>A data configuration method and device, and a rollback method and device for data configuration are applied to the technical field of information processing. A data configuration method comprises: receiving a data configuration operation request which includes an insertion data request, a deletion data request, or an update data request; distributing the operation serial number to the data configuration operation request; according to the data configuration operation request, recording the distributed operation serial number and the data which the data configuration operation request requests to be operated as the correspondence of a creation operation serial number (COSN), a deletion operation serial number (DOSN) and the data. A rollback method for data configuration comprises: obtaining a rollback operation serial number of data configuration; according to the recorded correspondence of the creation operation serial number, the deletion operation serial number and the data, obtaining the data corresponding to the condition that the creation operation serial number is less than or equal to (or more than or equal to) the rollback operation serial number, and the deletion operation serial number is more than (or less than) the rollback operation serial number, or that the deletion operation serial number is null. The present invention achieves the configuration operation of data and the rollback of the data configuration.</p> |
