[0043] Exemplary embodiments of the present disclosure will be described herein below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the present disclosure to those skilled in the art.

[0044] As Figure 1 shown, a flow diagram illustrating an embodiment of a data processing method provided by an embodiment of the present disclosure is shown, the data processing method can be applied to a service providing end system, the data processing method can include:

[0045] S01, in response to a transaction service request sent by a service requesting end system, mirroring backup of material information associated with the transaction service request, and obtaining a backup table.

[0046] The service providing end system and the service requesting end system can be a bank system for processing bank transaction flow data under a distributed architecture. The service providing end system can be a system for responding to transaction service requests under a distributed architecture. The service requesting end system can be a system for initiating transaction service requests under a distributed architecture.

[0047] It can be understood that under a distributed architecture, the service providing end system can be connected with multiple service requesting end systems, and provide relevant transaction services for the multiple service requesting end systems.

[0048] The embodiment of the present disclosure can perform image backup on the profile information associated with the transaction service request in the service request end system before modifying the profile information after receiving the transaction service request sent by the service request end system, realize real-time backup of the profile information, and obtain an independent backup table.

[0049] The embodiment of the present disclosure can pre-set a flow state field and a profile key value field in the transaction flow table of the service request end system. The flow state field is used to indicate the current processing state of the transaction flow generated by the transaction service. In general, the processing state of the transaction flow can include two states: processing and success. The profile key value field is used to record the key value of the modified profile field in the profile information during the transaction service, so as to locate the modified profile field in the profile information during the transaction service, and facilitate data rollback when the transaction fails.

[0050] The embodiment of the present disclosure can pre-set a profile state field in the profile information. The profile state field is used to indicate the modification confirmation state of the modified profile field in the profile information. In general, the modification confirmation state includes two states: confirmed and unconfirmed.

[0051] S02, modify the field value of the flow state field in the transaction flow table associated with the transaction service request to a preset processing parameter.

[0052] The preset processing parameter is used to indicate that the current processing state of the transaction flow generated by the transaction service is processing. The embodiment of the present disclosure can confirm the ongoing transaction service by the preset processing parameter, so as to be recognized and processed by the system.

[0053] S03, modify the field value of the profile state field in the profile information to a preset unconfirmed parameter.

[0054] The preset unconfirmed parameter is used to indicate that the modification confirmation state of the modified profile field in the profile information during the transaction service is unconfirmed. The embodiment of the present disclosure can identify and confirm that the modified profile field in the profile information has not been consistent with the service request end system by the preset unconfirmed parameter.

[0055] The profile information can be the data information stored by the transaction subject in the bank. For example, the profile information can include the account balance, income record, expenditure record and transaction detail record of the transaction subject.

[0056] S04, providing the transaction service to the service request end system, and obtaining the key value of the modified profile field in the profile information during the transaction service.

[0057] The transaction service can be a function service of a transaction service provided by a bank to a client. Alternatively, the transaction service can include cross-bank transaction and cross-institution transaction.

[0058] It can be understood that during the provision of the transaction service by the service providing end system to the service requesting end system, the corresponding data field in the data information can be modified, and the disclosed embodiments can collect the key value of the modified data field.

[0059] S05, record the key value into the data key value field in the transaction log table.

[0060] The disclosed embodiments can record the key value of the modified data field in the data information during the transaction service into the data key value field in the transaction log table, which facilitates the positioning of the modified data field during the transaction service, and is beneficial for data rollback in the case of transaction failure.

[0061] S06, in the case where the transaction success message sent by the service requesting end system is not obtained, scan the transaction log table whose log state field value is the preset processing parameter at a regular time, determine whether the transaction log corresponding to the transaction log table has timed out, and if so, perform step S07.

[0062] It can be understood that since there can be transaction log tables corresponding to multiple service requesting end systems, the disclosed embodiments can scan each transaction log table in the service providing end system at a regular time, determine the transaction log table whose log state field value is the preset processing parameter, and then determine whether the transaction log corresponding to the transaction log table has timed out.

[0063] In the case where the transaction log has timed out, the disclosed embodiments can find the corresponding data information according to the log information of the transaction log, and then determine the field value corresponding to the data state field in the data information. Generally, at this time, the field value corresponding to the data state field in the data information is the preset unconfirmed parameter. Since the transaction log has timed out, the disclosed embodiments can confirm that a bank error occurs, i.e., the data in the service providing end system and the service requesting end system is not consistent, in the case where the field value corresponding to the data state field is identified as the preset unconfirmed parameter.

[0064] Alternatively, if not timed out, continue to scan the transaction log table whose log state field value is the preset processing parameter at a regular time.

[0065] S07, in the case where the field value corresponding to the data state field is the preset unconfirmed parameter, initiate a log query to the service requesting end system, and obtain a log query result.

[0066] The embodiment of the present disclosure can query the transaction flow corresponding to the flow information of the transaction flow table in the service request end system, and confirm the transaction failure through the flow information corresponding to the transaction flow table.

[0067] S08, in the case of the flow query result being transaction failure, the key value recorded in the data key value field is used to roll back the data information to the state before the transaction service by using the backup table.

[0068] It can be understood that in the case of transaction failure, the service request end system will perform database level rollback. After confirming the transaction failure, the service providing end system determines that the modified data field in the data information belongs to invalid modification, thereby locating the modified data field in the data information by using the key value recorded in the data key value field, restoring the modified data field in the data information by using the corresponding data in the backup table, and ensuring the data consistency of the service providing end system and the service request end system.

[0069] S09, the field value of the data state field is modified to a preset confirmation parameter.

[0070] The preset confirmation parameter is used to indicate that the modification confirmation state of the data field in the current data information is confirmed. The embodiment of the present disclosure can confirm that the data information in the service providing end system is consistent with the service request end system after the data rollback of the data information.

[0071] Optionally, the embodiment of the present disclosure can also modify the field value of the flow state field in the transaction flow table to a preset success parameter in the case of obtaining the transaction success message sent by the service request end system. The field value of the data state field in the data information corresponding to the transaction flow table is modified to a preset confirmation parameter.

[0072] The service request end system will perform database level commit after the transaction is successful, and send a transaction success message to the service providing end system.

[0073] The embodiment of the present disclosure modifies the field value of the flow state field in the transaction flow table to a preset success parameter based on the transaction success message. The preset success parameter is used to indicate that the current processing state of the transaction flow generated by the transaction service is successful. The embodiment of the present disclosure can confirm that the transaction has been successfully completed through the preset success parameter.

[0074] The embodiment of the present disclosure can confirm that the current data information is consistent with the service request end system after confirming the transaction success, thereby modifying the field value of the data state field in the data information to a preset confirmation parameter.

[0075] Optionally, the embodiment of the present disclosure can also delete the backup table after step S09. The embodiment of the present disclosure can delete the backup table after the data rollback of the material information, thereby saving the system storage resources.

[0076] Optionally, the embodiment of the present disclosure can delete the backup table after step S11, thereby saving the system storage resources, or can retain the backup table after step S11, wait for the next time when the transaction service request sent by the service request end system is received, use the current material information to perform the image backup, and perform the data coverage on the backup table.

[0077] The data processing method provided by the embodiment of the present disclosure has low requirements on the service request end system, does not need to make large-scale modification on the existing bank distributed system, and simultaneously realizes the real-time forward update of the synchronous data of the service providing end system in multiple scenes, can be applied to the maintenance of the coverage data, and brings significant comprehensive benefits.

[0096] The data processing device provided by the present disclosure can be used in the distributed field or the financial field, and can be applied to a service providing end system. In response to a transaction service request sent by a service requesting end system, the data processing device performs image backup on material information associated with the transaction service request to obtain a backup table. The data processing device modifies a field value of a flow state field in a transaction flow table associated with the transaction service request to a preset processing in parameter.
