As shown in fig. 3, step S300 in the embodiment shown in fig. 1 may include:
s301, obtaining a data version and stored data of the data storage device 003 corresponding to the first device identifier;
the second device 002 may be a request processing device, such as a server. Each data storage device 003 can be a storage node, which together form a distributed storage system.
Alternatively, the first data may be answers to test questions, and each storage node may store answers to one test question from a plurality of examiners, for example: the first storage node stores answers of a plurality of examiners to the first test question; the second storage node stores answers of a plurality of examiners to the second test question; the third storage node stores the answers of a plurality of examiners to the third test question, and so on.
After acquiring the answer to a test question made by the examiner, the first device 001 may determine the device identifier of the data storage device 003 corresponding to the test question, and then generate a first request according to the determined device identifier and the acquired answer, and send the first request to the second device 002.
S302, comparing the first data with the obtained data stored in the data storage device 003 to obtain a comparison result;
optionally, the test questions may be test questions without standard answers, so that the comparison result of whether the answer in the first request is the most answer among the answers stored in the data storage device 003 can be obtained when the comparison is performed in step S302. When the answer in the first request is the most answer in the answers stored in the data storage device 003 as a result of the comparison, it may be determined that the answer in the first request is a valid answer; otherwise, the answer in the first request is determined to be an invalid answer.
S303, acquiring a data version of the data storage device 003 corresponding to the first device identifier at the current time;
s304, determining whether the data version obtained this time is consistent with the data version obtained last time, if so, executing the step S305; otherwise, the process returns to step S301.

Because different versions of data may cause different data updating results, the present invention needs to determine whether the version of the data during updating is consistent with the version of the data acquired before comparing the data, and when the versions of the data during updating are consistent, the present invention can update the data. For example: when the answer to the test question is compared, the result of comparing the answer in the first request with the answer to the test question of different data versions may be different. The invention needs to compare the answers before updating the data, so the data can be updated only when the data version of the answer to the test question used for comparing the answers is consistent with the data version of the answer to the test question used for updating. Therefore, the accuracy of the comparison result of the answer to the test question obtained by the invention is ensured, and the misjudgment of the answer in the first request is avoided.

After acquiring an answer to a test question made by an examiner, the first device 001 may determine the device identifier of the data storage device 003 corresponding to the test question, and then generate a first request according to the determined device identifier and the acquired answer and send the first request to the second device 002.
The data comparison unit is used for comparing the first data with the obtained data stored in the data storage device 003 to obtain a comparison result;
optionally, the test questions may be test questions without standard answers, so that the data comparison unit may obtain a comparison result of whether the answer in the first request is the most answer among the answers stored in the data storage device 003 when performing the comparison. When the answer in the first request is the most answer in the answers stored in the data storage device 003 as a result of the comparison, it may be determined that the answer in the first request is a valid answer; otherwise, the answer in the first request is determined to be an invalid answer.

The first result may be that the answer in the first request is the most answer among the answers stored in the data storage device 003. The first identification may be a valid answer identification.
Because different versions of data may cause different data updating results, the present invention needs to determine whether the version of the data during updating is consistent with the version of the data acquired before comparing the data, and when the versions of the data during updating are consistent, the present invention can update the data. For example: when the answer to the test question is compared, the result of the comparison between the answer in the first request and the answer to the test question of different data versions may be different. The invention needs to compare the answers before updating the data, so the data can be updated only when the data version of the answer to the test question used for comparing the answers is consistent with the data version of the answer to the test question used for updating. Therefore, the accuracy of the comparison result of the answer to the test question obtained by the invention is ensured, and the misjudgment of the answer in the first request is avoided.
