[0043] The following description of exemplary embodiments of the present invention is made in conjunction with the accompanying drawings, in which various details of the embodiments of the present invention are included to facilitate understanding. These details should be considered as merely exemplary. Therefore, it should be appreciated by those skilled in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present invention. Similarly, for the sake of clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

[0044] It should be noted that the collection, collection, updating, analysis, processing, use, transmission, and storage of user personal information involved in the technical solutions disclosed herein all comply with relevant laws and regulations, are used for legitimate purposes, and do not violate public order and good morals. Necessary measures are taken with respect to user personal information to prevent unauthorized access to user personal information data and to safeguard the security of user personal information, network security, and national security.

[0045] Figure 1 is a method for data display according to an embodiment of the present invention, such as Figure 1 As shown, including:

[0046] Step S101: determining an identifier of data to be queried based on a user query request.

[0047] When a user accesses an information system, the user's query request is obtained, and the corresponding identifier of the data to be queried is determined based on the user's query request. Specifically, the identifier of the corresponding data to be queried can be determined based on the data identifier information stored in the user's query request content; or the identifier of the corresponding data to be queried can be determined based on the identifier of the user's query request. The corresponding relationship between the identifier of the query request and the identifier of the data to be queried is a preset relationship.

[0048] Step S102: query the modification log and system initial data corresponding to the data identifier to be queried to obtain the query result.

[0049] According to the determined identifier of the data to be queried, it is queried whether the system initial data corresponding to the identifier and the modification log corresponding to the data are stored in the system to obtain the query result.

[0050] Step S103: Determine the display data corresponding to the data identifier to be queried according to the query result.

[0051] Based on the query results, determine whether there is data and modification log corresponding to the data identifier to be queried. If there is no data and modification log corresponding to the data identifier to be queried, the query result is a query failure message. If there is data and modification log corresponding to the data identifier to be queried, modify the system's initial data according to the modification log to obtain the displayed data.

[0052] Optionally, when there is no data and modification log corresponding to the data identifier to be queried, the query result is query failure information, the system imported data is obtained, it is determined that the system imported data is the first imported data, and the system imported data is directly stored in the system as display data.

[0053] According to the data display method provided by an embodiment of the present invention, when a user accesses an information system, display data can be generated based on the modification log of the data to be queried and the system initial data. By setting the data modification log, the user's modification information on the data can be saved to avoid the modified data from being overwritten, thereby ensuring the accuracy and efficiency of the system's stored data.

[0054] Optionally, before querying the modification log and system initial data corresponding to the data identifier to be queried, the method further includes: in response to a user modifying the system initial data, obtaining modification data resulting from the user's modification of the system initial data; if the modification data differs from the system initial data, generating a modification log based on the modification data. For system initial data stored in the system, if this is the first time the user's modification data is obtained, the user's modification data is compared with the system initial data. If the user's modification data differs from the system initial data, a modification log containing the user's modification data is generated; if the user's modification data and the system initial data are the same, no modification log is generated.

[0055] Optionally, determining the display data corresponding to the data identifier to be queried based on the query result includes: if a modification log corresponding to the data identifier to be queried is found, determining the display data based on the modification log; if no modification log corresponding to the data identifier to be queried is found, using the system's initial data as the display data. When the system queries the system's stored data, if a modification log corresponding to the data identifier to be queried is found, the modification log is merged with the system's initial data to obtain the display data; if no modification log corresponding to the data identifier to be queried is found, indicating that no modification record exists for the data, the system's initial data is displayed as the display data.

[0056] The data display method provided by the embodiment of the present invention can generate a data modification log based on the user's modified data, and when the user accesses the information system again, generate display data based on the modification log of the data to be queried and the system initial data. By setting the data modification log, the user's modification information on the data can be saved, avoiding data from being overwritten, and ensuring the accuracy and efficiency of the system's stored data.

[0057] Optionally, after determining the display data corresponding to the data identifier to be queried based on the query results, the method further includes: in response to a user modifying the display data, obtaining target data resulting from the user's modification of the display data; and updating a modification log based on the target data and the system's initial data. When the user performs data maintenance, the user modifies the display data based on the system's display data, and the system stores the modified target data. By comparing the target data with the system's initial data, the system updates the modification log corresponding to the compared data.

[0058] The data display method provided by an embodiment of the present invention can generate and update a data modification log based on user modification data, enabling the system to generate corresponding display data based on the modification log and the system's initial data. The display data retains the user's modification information. This prevents data stored in the system from being overwritten, ensuring the accuracy and efficiency of the system's stored data.

[0059] Optionally, based on the target data and the system initial data, the modification log is updated, including: determining whether the target data is the same as the system initial data, and generating a modification record based on the target data if the target data is different from the system initial data; and updating the modification log based on the modification record. Compare the target data obtained after the user modification with the system initial data to determine whether the two data are the same. Specifically, determine whether there is different data content in the two data. For example, if the value of field1 in the target data is 1, and the value of field1 in the system initial data is 0, then it is determined that there is different data content in the two data. If the two data are different, a user modification record is generated based on the target data, for example, the modification record is that field1 is 1. Update the data modification log based on the modification record to obtain the latest data modification information.

[0060] Optionally, updating the modification log based on the target data and the system initial data includes: determining whether the target data is identical to the system initial data and the display data; if the target data is different from both, generating a modification record based on the target data; and updating the modification log based on the modification record. When updating the modification log, first determine whether the target data modified by the user is identical to both the system initial data and the display data. If the target data is determined to be different from both, then generate a modification record based on the user-modified data, and then update the data modification log based on the modification record.

[0061] Optionally, when updating the modification log, a determination is made as to whether the target data is identical to the system's initial data. If so, the user is deemed not to have modified the data, and the modification log is not updated. If not, the user is deemed to have modified the data, and a user modification record is obtained by comparing the target data with the system's initial data. The modification log is then updated based on the user modification record. Specifically, the modification log generated with the new user modification record overwrites the original modification log.

[0062] Optionally, when updating the modification log, a determination is made as to whether the target data and the displayed data are identical. The displayed data is the data obtained by merging the system's initial data and the corresponding modification log. If the target data and the displayed data are identical, the original modification log is retained and not updated. If the target data and the displayed data are different, a user modification record based on the displayed and target data is generated, and the original modification log is updated based on the modification record. Specifically, a modification log is generated based on the modification record, and the generated modification log is merged with the original modification log to obtain an updated modification log. Modifications to the same data content are subject to the generated modification log.

[0063] Optionally, the method further includes: obtaining system update data in response to a system data update operation; and updating the system initial data based on the system update data. If the information system needs to import the latest update data, only the system initial data stored in the system needs to be updated to the update data, without modifying the data modification log, and retaining the user's maintenance data.

[0064] The data display method provided by an embodiment of the present invention can generate and update a data modification log based on user modification data. When a user accesses an information system, display data is generated based on the modification log of the data to be queried and the system's initial data. By setting up a data modification log, user modifications to the data can be saved, preventing data from being overwritten and ensuring the accuracy and efficiency of the system's stored data. When new data is imported, only the system's initial data is overwritten, without affecting the modification log. User-modified data is retained, further ensuring the accuracy of the system's stored data.

[0065] Figure 2A flow chart for determining a data modification log is shown, in which record A is the system initial data in the above-mentioned data display method. As shown in the figure, after record A is imported into the system, when the user accesses record A in the information system, it is determined whether record A has a corresponding modification log L1. If modification log L1 exists, record A and modification log L1 are merged to obtain record A1, and record A1 is returned to the user; if modification log L1 does not exist, the data of record A is directly returned, recorded as A1. The user manually modifies record A1 through the operational interface of the information system to obtain B1 and save record B1. B1 is compared with record A. If the comparison results are consistent, record A remains unchanged; if the comparison results are inconsistent, field modification information L1 is obtained based on records B1 and A, and L1 is saved.

[0066] Figure 3 This diagram shows the changes in data and modification logs during a user modification process. As shown, before the user modified data, record A included data in field 1, field 2, and field 3, with corresponding values ​​of 1, 2, and 3. The user manually modified the record B, which included data in field 1, field 2, and field 3, with corresponding values ​​of 11, 2, and 3. By comparing records A and B, modified record L1 was obtained, including data in field 1, with a corresponding value of 11. By merging L1 and A, merged data B was obtained, i.e., the displayed data, including data in field 1, field 2, and field 3, with corresponding values ​​of 11, 2, and 3.
