[0030] Figure 1 is an optional flow chart of the file comparison method provided in the embodiment of the present application. Figure 1 The method may include but is not limited to steps S101 to S106.

[0031] Step S101, obtaining configuration attribute information of the target file; Step S102, grouping the target files based on the configuration attribute information to obtain a comparison file group; Step S103, constructing a file basic parameter table and a file structure definition table based on the comparison file group and the configuration attribute information, wherein the file basic parameter table is used to describe the file attributes of the comparison file group, and the file structure definition table is used to describe the file configuration of the comparison file group; Step S104, based on the preset file identification parameters and the file basic parameter table, a target file group is screened out from the comparison file group, wherein the target file group includes a reference file and an update file; Step S105, based on the file basic parameter table and the file structure definition table, the reference file is parsed to obtain the reference file field, and based on the file basic parameter table and the file structure definition table, the update file is parsed to obtain the update file field; Step S106: Based on the reference file field, the update file field and the file structure definition table, the update file is compared with the reference file.

[0032] In steps S101 to S106 shown in the embodiment of the present application, the target files are grouped by obtaining the configuration attribute information of the target files to obtain a comparison file group, and then a file basic parameter table for describing the file attributes of the comparison file group and a file structure definition table for describing the file configuration of the comparison file group are constructed based on the comparison file group and the configuration attribute information. Furthermore, based on the preset file identification parameters and the file basic parameter table, reference files and update files that need to be compared are screened out from the comparison file group. Secondly, based on the file basic parameter table and the file structure definition table, the reference file is parsed to obtain the reference file field, and based on the file basic parameter table and the file structure definition table, the update file is parsed to obtain the update file field. Finally, based on the reference file field, the update file field and the file structure definition table, the update file is compared with the reference file. Therefore, the present application obtains the configuration attribute information of the target file, and then uses the configuration attribute information to group the target file to obtain a comparison file group, thereby avoiding completely unrelated files from appearing in the same comparison file group, thereby improving the pertinence and accuracy of the file comparison. Furthermore, according to the comparison file group and the configuration attribute information, a file basic parameter table and a file structure definition table are constructed, which can provide detailed reference information for subsequent file comparisons. Secondly, according to the preset file identification parameters and the file basic parameter table, the target file group is screened out from the comparison file group, and according to the file basic parameter table and the file structure definition table, the reference file is parsed to obtain the reference file field, and according to the file basic parameter table and the file structure definition table, the updated file is parsed to obtain the updated file field, thereby reducing the degree of manual participation in file field acquisition, thereby improving the efficiency and accuracy of file comparison. Finally, according to the reference file field, the updated file field and the file structure definition table, the updated file is compared with the reference file, further reducing the degree of manual participation in the file comparison process and improving the efficiency and accuracy of file comparison.

[0033] In step S101 of some embodiments, the configuration attribute information may be a collection of file configuration information and file attribute information of the target file, wherein the file configuration information includes information such as the field name, field position, maximum length of the field, whether the field is a primary key, and whether the field is a whitelist, and the file attribute information includes information such as the index path, file date, file name, file content type, file separator type, and file owner of the target file.

[0034] The present application can obtain configuration attribute information of the target file by querying the configuration file of the target file, and can also obtain file configuration information and file attribute information of the target file by querying the structure and attributes of the target file, and finally, combine the file configuration information and file attribute information of the target file to obtain configuration attribute information.

[0035] In step S102 of some embodiments, by querying the file contents of the target files, target files with similar contents are grouped into the same group, thereby forming a comparison file group.

[0036] It is important to know that by grouping the target files so that target files with similar contents are grouped into the same group to form a comparison file group, the increase in file comparison time caused by comparison between irrelevant files during the file comparison process can be reduced, thereby improving the efficiency of file comparison.

[0037] In step S103 of some embodiments, the comparison file groups obtained by the above classification are numbered to obtain a file group identifier for representing the identity of the comparison file group. Furthermore, the file group identifier is combined with the configuration attribute information of each file in the comparison file group to obtain a file basic parameter table for describing the file attributes of the comparison file group and a file structure definition table for describing the file configuration of the comparison file group.

[0038] For details, see Figure 2 In some embodiments, step S103 may include but is not limited to steps S201 to S206: Step S201, performing group identification on the comparison file group to obtain a file group identification; Step S202, constructing a group identification field based on the file group identification; Step S203, constructing a file attribute field based on the file attribute information; Step S204, constructing a file configuration field based on the file configuration information; Step S205, concatenating the group identification field and the file attribute field to obtain a file basic parameter table; Step S206, concatenating the group identification field and the file configuration field to obtain a file structure definition table.

[0039] In step S201 of some embodiments, the comparison file group can be numbered according to the file content of the comparison file group to obtain a group identifier of the comparison file group, that is, a file group identifier. For example, in a scenario in the financial field, if all the files in the comparison file group A are medical insurance files, then by group identifying the comparison file group, a file group identifier of the medical insurance file group No. 1 can be generated.

[0040] In steps S202 to S204 of some embodiments, a group identification field of the comparison file group can be constructed based on the file group identification of the comparison file group, and then a file attribute field and a file configuration field can be constructed respectively based on the configuration attribute information of each file in the comparison file group, wherein the file attribute field includes the file attribute information of each file in the comparison file group, and the file configuration field includes the file configuration information of each file in the comparison file group.

[0041] In step S205 and step S206 of some embodiments, the group identification field of the comparison file group is concatenated with the file attribute field of the comparison file group to form a data table, and a file basic parameter table for describing the file attributes of the comparison file group can be obtained. The group identification field of the comparison file group is concatenated with the file configuration field of the comparison file group to form a data table, and a file structure definition table for describing the file configuration of the comparison file group can be obtained.

[0042] In steps S201 to S206 shown in the present embodiment, a file group identification is obtained by group identification of the comparison file group, so that the comparison file group that needs to be compared can be quickly screened out later. Furthermore, a group identification field is constructed based on the file group identification, a file attribute field is constructed based on the file attribute information, and a file configuration field is constructed based on the file configuration information. The group identification field and the file attribute field are concatenated to obtain a file basic parameter table, and the group identification field and the file configuration field are concatenated to obtain a file structure definition table, which can provide detailed reference information for subsequent file comparison and file parsing steps, thereby reducing the time for file information query and improving the efficiency of file comparison.

[0043] In step S104 of some embodiments, the file identification parameter may be a file group identification of a comparison file group that needs to be compared.

[0044] This method can perform an identification query on the file basic parameter table based on the pre-set file identification parameters to obtain the target group identification, and then query the index path of the comparison file group corresponding to the target group identification in the file basic parameter table to obtain the file path. Further, according to the file path, the specified file is read to obtain the target file group.

[0045] For details, see Figure 3 In some embodiments, step S104 may include but is not limited to steps S301 to S304: Step S301, selecting a target group identifier from the file group identifiers of the comparison file group based on the file identifier parameter; Step S302, based on the target group identifier, perform a path query on the file basic parameter table to obtain the file path; Step S303, based on the file path, read the file to obtain the reference file and the update file; Step S304: combine the reference file and the update file to obtain a target file group.

[0046] In step S301 of some embodiments, the target group identifier can be obtained by searching the file basic parameter table for a file group identifier that is identical to the file identifier parameter. It should be noted that the target group identifier refers to the identity information of the comparison file group that needs to be compared.

[0047] In step S302 of some embodiments, the file basic parameter table includes the index path of the file, so the file paths of the multiple files can be obtained by querying the index path corresponding to the target group identifier in the file basic parameter table.

[0048] In step S303 of some embodiments, the file is read according to the above file path to obtain a reference file and an update file. It should be noted that the timestamp data of the reference file is generally earlier than the timestamp data of the update file.

[0049] In step S304 of some embodiments, the reference file and the update file read out are combined into a folder, so as to obtain a target file group corresponding to the preset file identification parameters.

[0050] In steps S301 to S304 shown in the present embodiment, a target group identifier is selected from the file group identifiers of the comparison file group according to the file identifier parameters, and then a path query is performed on the file basic parameter table according to the target group identifier to obtain the file path. Next, according to the file path, the file is read to obtain the reference file and the update file. Finally, the reference file and the update file are combined to obtain the target file group, so that the comparison file group that needs to be compared can be accurately obtained, thereby improving the accuracy of the file comparison.

[0051] In step S105 of some embodiments, the reference file type and the update file type can be obtained by querying the file basic parameter table for the file types of the reference file and the update file. Secondly, according to the file types of the reference file and the update file and the pre-set file field query method, the file basic parameter table and the file structure definition table are queried to obtain the reference field structure information and the update field structure information. Finally, according to the reference field structure information and the update field structure information, the reference file and the update file are read for fields to obtain the reference file fields and the update file fields.

[0052] For details, see Figure 4 In some embodiments, step S105 may include but is not limited to steps S401 to S405: Step S401, based on the file basic parameter table, query the file type of the reference file to obtain the reference file type, and based on the file basic parameter table, query the file type of the update file to obtain the update file type; Step S402, based on the reference file type, the file basic parameter table and the file structure definition table, perform a field structure query on the reference file to obtain reference field structure information; Step S403, based on the update file type, the file basic parameter table and the file structure definition table, perform a field structure query on the update file to obtain update field structure information; Step S404, extracting information from the reference file based on the reference field structure information to obtain the reference file field; Step S405: extract information from the update file based on the update field structure information to obtain the update file fields.

[0053] In step S401 of some embodiments, by querying the file type of the target file group in the file basic parameter table, the file type of each file in the target file group, ie, the reference file type and the update file type, can be obtained.

[0054] It is important to know that the file types in the file basic parameter table include variable-length file types and fixed-length file types. The variable-length file type indicates that the field length and file format of the file may change, while the fixed-length file type indicates that the field length and file format of the file will not change.

[0055] In step S402 of some embodiments, the field structure in the reference file can be clarified based on the reference file type. When the reference file type is a fixed-length file type, the field structure of the reference file in the file structure definition table can be directly queried to obtain the reference field structure information. When the reference file type is a variable-length file type, it is necessary to determine the delimiter type of the reference file through the file basic parameter table, and then perform file structure parsing to obtain the reference field structure information.

[0056] For details, see Figure 5 In some embodiments, step S402 may include but is not limited to steps S501 to S503: Step S501, if the reference file type is a fixed-length file type, then based on the reference file, a field structure query is performed on the file structure definition table to obtain reference field structure information; Step S502: If the reference file type is a variable-length file type, a delimiter type query is performed on the file basic parameters based on the reference file to obtain a field delimiter; Step S503: perform structural analysis on the reference file based on the field separator to obtain reference field structure information.

[0057] In step S501 of some embodiments, when the reference file type of the reference file is a fixed-length file type, it indicates that the fields of the reference file do not need to be separated by separators. Therefore, the field structure of the reference file in the file structure definition table can be directly queried to obtain the reference field structure information of the reference file.

[0058] In step S502 of some embodiments, when the reference file type of the reference file is a variable-length file type, it indicates that the fields of the reference file need to be separated by separators. Therefore, before parsing the reference file, it is also necessary to clarify the separator type of the reference file. Specifically, the field separator of the reference file can be obtained by querying the separator type of the reference file in the file basic parameter table.

[0059] In step S503 of some embodiments, after the field separator of the reference file is clarified, the field separation position in the reference file can be identified according to the field separator, thereby implementing structural analysis of the reference file and obtaining reference field structure information.

[0060] In steps S501 to S503 shown in the present embodiment, when the reference file type is a fixed-length file type, a field structure query is performed on the file structure definition table according to the reference file to obtain reference field structure information; when the reference file type is a variable-length file type, a delimiter type query is performed on the file basic parameters according to the reference file to obtain the field delimiter; then, based on the field delimiter, the reference file is structurally parsed to obtain reference field structure information, which can improve the recognition accuracy of the field structure information, thereby improving the extraction accuracy of the reference file fields.

[0061] In step S403 of some embodiments, a method for performing a field structure query on the update file based on the update file type, the file basic parameter table and the file structure definition table to obtain update field structure information is similar to a method for performing a field structure query on the reference file based on the reference file type, the file basic parameter table and the file structure definition table to obtain reference field structure information, and therefore is not described in detail.

[0062] In step S404 of some embodiments, the specific location of each field in the reference file can be queried based on the reference field structure information, and then the field information of the reference file, namely the reference file field, can be extracted based on the queried location information.

[0063] For details, see Figure 6 In some embodiments, step S404 may include but is not limited to steps S601 to S602: Step S601, based on the reference field structure information, perform field query on the reference file to obtain reference field location information; Step S602: Based on the reference field position information, field extraction is performed on the reference file to obtain the reference file field.

[0064] In step S601 of some embodiments, the reference field structure information includes the position information of each field in the reference file. Therefore, the reference field position information of the reference file can be queried based on the reference field structure information.

[0065] In step S602 of some embodiments, field information of the reference file, ie, the reference file field, can be obtained by performing field extraction on the area indicated by the reference field position information.

[0066] In steps S601 to S602 shown in this embodiment, a field query is performed on the reference file based on the reference field structure information to obtain the reference field position information, and then a field extraction is performed on the reference file based on the reference field position information to obtain the reference file field. The field information of the reference file can be accurately extracted, thereby improving the accuracy of file comparison.

[0067] In step S405 of some embodiments, the method of extracting information from the update file based on the update field structure information to obtain the update file field is similar to the method of extracting information from the reference file based on the reference field structure information to obtain the reference file field, so it is not repeated here.

[0068] In steps S401 to S405 shown in the present embodiment, a file type query is performed on the reference file according to the file basic parameter table to obtain the reference file type, and a file type query is performed on the update file according to the file basic parameter table to obtain the update file type. Next, a field structure query is performed on the reference file according to the reference file type, the file basic parameter table and the file structure definition table to obtain reference field structure information. A field structure query is performed on the update file according to the update file type, the file basic parameter table and the file structure definition table to obtain update field structure information. Finally, information is extracted from the reference file according to the reference field structure information to obtain the reference file field. Information is extracted from the update file according to the update field structure information to obtain the update file field. This can reduce the degree of manual involvement in the process of extracting file fields, reduce the probability of file field extraction errors, and thus improve the accuracy of file comparison.

[0069] In step S106 of some embodiments, after extracting the reference file fields of the reference file and the update file fields of the update file, targeted field comparison can be performed on the reference file fields and the update file fields by querying the relevant field whitelist information in the file structure definition table, thereby achieving file comparison between the reference file and the update file.

[0070] For details, see Figure 7 In some embodiments, step S106 may include but is not limited to steps S701 to S702: Step S701, based on the update file and the reference file, perform a field whitelist query on the file structure definition table to obtain non-comparison field information; Step S701 : Based on the non-comparison field information, the reference file field and the update file field are compared to obtain file comparison information, wherein the file comparison information is used to indicate the difference between the reference file and the update file.

[0071] In step S701 of some embodiments, the file structure definition table contains field whitelist information for each comparison file group, wherein the field whitelist information is used to describe field information in the comparison file group that does not need to be compared. Therefore, the present application can clearly refer to the field information that does not need to be compared in the file and update file, that is, the non-comparison field information, by querying the relevant field whitelist information in the file structure definition table.

[0072] In step S702 of some embodiments, the reference file field and the update file field are masked based on the non-comparison field information, so that only the comparison fields that need to be compared remain in the reference file field and the update file field, and file comparison information representing the differences between the reference file and the update file is generated based on the comparison results of the comparison fields.

[0073] In steps S701 to S702 shown in this embodiment, a field whitelist query is performed on the file structure definition table based on the update file and the reference file to obtain non-comparison field information, and then based on the non-comparison field information, a field comparison is performed between the reference file field and the update file field to obtain file comparison information, which can reduce the time for file comparison and thus improve the efficiency of file comparison.

[0074] The present application obtains configuration attribute information of the target file, and then uses the configuration attribute information to group the target file to obtain a comparison file group, thereby avoiding completely unrelated files from appearing in the same comparison file group, thereby improving the pertinence and accuracy of file comparison. Furthermore, according to the comparison file group and the configuration attribute information, a file basic parameter table and a file structure definition table are constructed, which can provide detailed reference information for subsequent file comparisons. Secondly, according to the preset file identification parameters and the file basic parameter table, the target file group is screened out from the comparison file group, and according to the file basic parameter table and the file structure definition table, the reference file is parsed to obtain the reference file field, and according to the file basic parameter table and the file structure definition table, the updated file is parsed to obtain the updated file field, thereby reducing the degree of manual participation in file field acquisition, thereby improving the efficiency and accuracy of file comparison. Finally, according to the reference file field, the updated file field and the file structure definition table, the updated file is compared with the reference file, thereby further reducing the degree of manual participation in the file comparison process and improving the efficiency and accuracy of file comparison.
