[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0024] Embodiment 1

[0025] Figure 1 This is a flow chart of a data model switching method provided in the first embodiment of the present invention. This embodiment can be applied to the case of switching data models with different structures, especially to the application scenario where the data model is relatively complex and the data switching process must ensure that the data is completely consistent and the existing business is running uninterrupted. The method can be executed by a data model switching device, which can be implemented by software and / or hardware and integrated into a server. Figure 1 As shown, the method specifically comprises the following steps:

[0026] S110: Receive a current data request sent by the client.

[0027] The client may refer to an application software program that provides local services to users. The current data request may refer to a currently received data request. The current data request may include a data read request, such as a data query request, or a data write request, such as a data registration request.

[0028] S120. Based on the current processing mode, the current data request is processed, the current response data corresponding to the current data request is determined, and the current response data is returned to the client, wherein the initial mode of the current processing mode is the data verification mode, the data verification mode performs data verification on the original data model and the improved data model, and determines the mode of the current response data corresponding to the current data request based on the data verification result.

[0029] Among them, the current processing mode may refer to the way of processing the current data request. The current response data may refer to the request processing result. The data model may refer to a database used to store data. The data model may include: a hierarchical model, a network model or a relational model. The fundamental difference between them lies in the different ways of expressing the connection between data. The original data model may refer to the data model originally used by the server. The improved data model is a data model obtained after redesign and improvement. The improved data model in this embodiment has a different data structure from the original data model, so it is necessary to verify the data consistency after data synchronization. The improved data model and the original data model can achieve a one-to-one correspondence through a single field and multiple joint fields, that is, a field mapping relationship, so as to perform data synchronization operations and data verification operations based on the field mapping relationship.

[0030] Specifically, when it is necessary to switch the data model, the data verification mode is used as the initial mode of the current processing mode, so that the data verification mode is used to verify the original data model and the improved data model, and the current response data corresponding to the current data request is determined based on the data verification result, thereby realizing online automatic verification of the data of the original data model and the improved data model. For example, the original request processing logic can be used to obtain the first field data corresponding to the current data request from the original data model, and the first field data is logically processed to obtain the first business data that can be returned to the client. At the same time, the improved request processing logic can also be used to obtain the second field data corresponding to the current data request from the improved data model, and the second field data is logically processed to obtain the second business data that can be returned to the client. This embodiment can synchronously perform data verification operations and response data return operations. For example, it can verify whether the first field data matches the second field data based on the field mapping relationship, and verify whether the first business data and the second business data are the same. When the verification is successful, that is, the first field data matches the second field data and the first business data and the second business data are the same, the second business data can be returned to the client as the current response data corresponding to the current data request, or, whether the verification is successful or failed, the first business data can be directly returned to the client as the current response data corresponding to the current data request to improve the response speed. If the verification fails, that is, the first field data does not match the second field data and / or the first business data and the second business data are not the same, an alarm message can be generated, and the alarm message can be reported to relevant personnel to promptly remind relevant personnel to check and maintain. This embodiment can also asynchronously perform data verification operations and response data return operations to further improve the response speed. For example, the first business data can be directly returned to the client as the current response data corresponding to the current data request, and at the same time, it can be asynchronously checked whether the first field data matches the second field data, and whether the first business data and the second business data are the same. When the verification fails, an alarm message can be generated, thereby further improving the response speed and ensuring that the data is completely consistent during the data model switching process.

[0031] S130. If it is detected that the preset data verification success condition is currently met, the current processing mode is updated from the data verification mode to the data model switching mode, wherein the data model switching mode is a mode for determining the current response data corresponding to the current data request based on the improved data model.

[0032] The preset data verification success condition may be a pre-set condition used to indicate that the current processing mode can be updated. For example, the preset data verification success condition may mean that no alarm information is generated within a preset time period, or that no alarm information is generated after a preset number of requests are processed.

[0033] Specifically, when it is detected that the current request processing situation meets the preset data verification success condition, it indicates that the data of the original data model is consistent with the data of the improved data model. At this time, the current processing mode can be updated from the data verification mode to the data model switching mode, and the operation of step S110 can be returned to execute, so that the data model switching mode can be used to switch the original data model to the improved data model, and the current response data corresponding to the current data request received subsequently can be directly determined based on the improved data model. By updating the current processing mode, the seamless switching of the data model can be achieved without affecting the operation of the existing business, improving the switching efficiency, and without the need for improvements at the business level, making the business unaware and reducing the switching cost.

[0034] The technical solution of this embodiment pre-sets the data verification mode and the data model switching mode, and uses the data verification mode as the initial mode of the current processing mode, so that in the data verification mode, the original data model and the improved data model can be verified, and the current response data corresponding to the current data request sent by the client is determined based on the data verification result, so that the data of the original data model and the improved data model can be automatically verified online without human intervention, thereby ensuring data consistency. If it is detected that the preset data verification success condition is currently met, the current processing mode is updated from the data verification mode to the data model switching mode, so that in the data model switching mode, the current response data corresponding to the current data request sent by the client can be determined based on the improved data model, so that the original data model is switched to the improved data model, and the seamless switching of the data model is achieved without affecting the operation of the existing business, thereby improving the switching efficiency.

[0035] Based on the above technical solution, step S120 may include: based on the current request identifier in the current data request, detecting whether the current data request is within the current verification request range, and the current verification request range is updated based on the current verification result; if so, based on the current processing mode, processing the current data request to determine the current response data corresponding to the current data request; if not, determining the current response data corresponding to the current data request based on the original data model.

[0036] The current verification request range can be a user-configured set of data request identifiers currently used for data verification. The current verification request range can be configured and updated based on the current verification result. For example, if all data requests within the current verification request range are successfully verified, the current verification request range can be increased to verify the processing of more data requests and ensure data consistency.

[0037] Specifically, when the amount of data is large, you can configure the current verification request range to give priority to verifying a small number of data requests, and then expand the verification range of the data request after there is no problem, so as to further avoid affecting the response speed. When the current processing mode is the data verification mode, you can detect whether the current data request is within the current verification request range. If so, it indicates that the current data request can be verified. At this time, based on the data verification mode, the original data model and the improved data model can be verified, and the current response data corresponding to the current data request can be determined based on the data verification result. If it is not within the current verification request range, it means that there is no need to verify the current data request. At this time, the original request processing logic can be used to determine the current response data corresponding to the current data request based on the original data model, so that the step-by-step verification of the data model can be achieved.

[0038] On the basis of the above technical solution, before step S110, the method may further include: based on the field mapping relationship between the original data model and the improved data model, synchronously storing the original field data in the original data model into the improved data model.

[0039] Specifically, after obtaining the improved data model, the improved field data corresponding to the original field data in the original data model can be determined based on the field mapping relationship between the original data model and the improved data model, and the improved field data can be stored in the improved data model, thereby realizing data synchronization, and performing data verification after data synchronization to ensure the accuracy and consistency of data synchronization.

[0040] Embodiment 2

[0041] Figure 2 A flowchart of a data model switching method provided in Embodiment 2 of the present invention. In this embodiment, based on the above embodiments, the data verification mode may include: field data verification mode and business data verification mode. Accordingly, the initial mode of the current processing mode is the field data verification mode. On this basis, the step "if it is detected that the preset data verification success condition is currently met, the current processing mode is updated from the data verification mode to the data model switching mode" is further optimized. The explanations of the terms that are the same or corresponding to the above embodiments are not repeated here.

[0042] See also Figure 2 The data model switching method provided in this embodiment specifically includes the following steps:

[0043] S210: Receive a current data request sent by the client.

[0044] S220. Based on the current processing mode, process the current data request, determine the current response data corresponding to the current data request, and return the current response data to the client, wherein the initial mode of the current processing mode is the field data verification mode.

[0045] The field data validation mode may refer to a mode for validating the field data of the original data model and the improved data model and determining the current response data corresponding to the current data request. The field data may refer to the original data stored in the data model, that is, the unprocessed underlying data.

[0046] Specifically, when the data model needs to be switched, the field data verification mode is used as the initial mode of the current processing mode, so that the field data verification mode is used to first verify the field data of the original data model and the improved data model to ensure the consistency of the field data. For example, during the field data verification process, the data verification operation and the response data return operation can be performed synchronously or asynchronously to ensure the response speed.

[0047] Exemplarily, when the current processing mode is the field data verification mode, S220 may include: obtaining first field data corresponding to the current data request from the original data model, and obtaining second field data corresponding to the current data request from the improved data model; determining the current response data corresponding to the current data request based on the first field data, and based on the field mapping relationship between the original data model and the improved data model, asynchronously verifying whether the first field data and the second field data match, and if they do not match, generating an alarm message.

[0048] Specifically, the original request processing logic can be used to obtain the first field data corresponding to the current data request from the original data model, and the improved request processing logic can also be used to obtain the second field data corresponding to the current data request from the improved data model. After obtaining the first field data, the first field data can be directly processed, and the obtained business data is returned to the client as the current response data. While determining the current response data, an asynchronous thread can be started, and the asynchronous thread can be used to verify whether the first field data and the second field data match based on the field mapping relationship. If they do not match, an alarm message can be generated, and the alarm message can be reported to relevant personnel to promptly remind relevant personnel to check and maintain. Therefore, through asynchronous operations, the response speed can be guaranteed while ensuring the accuracy of request processing, avoiding affecting the user experience.

[0049] For example, if the current data request is a data query request, the field data queried from the original data model can be used as the first field data, and the field data queried from the improved data model can be used as the second field data. The first field data is processed to obtain the query results to be displayed on the client, and the query results are returned to the client as the current response data. At the same time, the first field data and the second field data are asynchronously checked, that is, whether the correspondence between the first field data and the second field data conforms to the field mapping relationship. If not, an alarm message is generated.

[0050] For another example, if the current data request is a registration request, the registration information in the registration request can be written into the original data model, and the result of whether the writing is successful can be used as the first field data. The registration information in the registration request can be written into the improved data model, and the result of whether the writing is successful can be used as the second field data. The first field data is processed to obtain the registration result to be displayed on the client, and the registration result is returned to the client as the current response data. At the same time, the first field data and the second field data are asynchronously checked, that is, whether the correspondence between the first field data and the second field data conforms to the field mapping relationship. If not, an alarm message is generated.

[0051] S230. If it is detected that the preset data verification success conditions are currently met, the current processing mode is updated in sequence according to the order of field data verification mode, business data verification mode and data model switching mode, and the updating is stopped when the current processing mode is the data model switching mode.

[0052] Specifically, when it is detected that the current request processing situation meets the preset data verification success condition, it indicates that the field data of the original data model and the improved data model are consistent. At this time, the current processing mode can be updated from the field data verification mode to the business data verification mode, and the operation of step S110 can be returned to perform business data verification on the original data model and the improved data model again using the business data verification mode to ensure the consistency of the business data. Among them, the business data can refer to the data to be displayed by the client, that is, the data returned to the client through the interface.

[0053] Exemplarily, when the current processing mode is the business data verification mode, S220 may include: obtaining the third field data corresponding to the current data request from the original data model, and determining the first business data based on the third field data; obtaining the fourth field data corresponding to the current data request from the improved data model, and determining the second business data based on the fourth field data; performing data verification on the first business data and the second business data, and determining the current response data corresponding to the current data request based on the data verification result.

[0054] Specifically, the original request processing logic can be used to obtain the third field data corresponding to the current data request from the original data model, and the third field data can be processed to obtain the first business data that can be returned to the client. At the same time, the improved request processing logic can also be used to obtain the fourth field data corresponding to the current data request from the improved data model, and the fourth field data can be processed to obtain the second business data that can be returned to the client. This embodiment can determine whether the second business data after using the improved data model is consistent with the original first business data by verifying whether the first business data is the same as the second business data, thereby further ensuring that the data after the data model is switched is completely consistent.

[0055] Exemplarily, data verification is performed on the first business data and the second business data, and the current response data corresponding to the current data request is determined based on the data verification result, which may include: if the first business data and the second business data are verified to be the same, the second business data is used as the current response data corresponding to the current data request; if the first business data and the second business data are verified to be different, the first business data is used as the current response data corresponding to the current data request, and an alarm message is generated. When the first business data and the second business data are the same, the second business data after using the improved data model is returned to the client as the current response data, so that the data model can be gradually switched.

[0056] Specifically, when it is detected that the current request processing situation meets the preset data verification success condition, it indicates that the business data of the original data model and the improved data model are also consistent. At this time, the current processing mode can be updated from the business data verification mode to the data model switching mode, and the operation of step S110 can be returned to execute, so that the data model switching mode can be used to switch the original data model to the improved data model, and the current response data corresponding to the current data request received subsequently can be directly determined based on the improved data model. By updating the current processing mode, the seamless switching of the data model can be achieved without affecting the operation of the existing business, improving the switching efficiency, and without the need for improvements at the business level, making the business unaware and reducing the switching cost.

[0057] The technical solution of this embodiment utilizes the field data verification mode and the business data verification mode to perform field data verification and business data verification on the original data model and the improved data model respectively, thereby realizing step-by-step verification of the data model, so that problems can be discovered and solved in time, further improving switching efficiency.
