Description

Technical Field

[0001] This application relates to the field of data analysis, specifically to a data processing method, apparatus, device, and medium. Background Technology

[0002] In some workflow-based business approval systems, the approval data is edited and saved multiple times during the workflow process. The relevant technologies directly update and save the current data, which cannot record the historical state of the business data, nor can they associate the business data snapshot with the approval process node at that time. Therefore, it is impossible to query the business data based on the approval history.

[0003] In addition, in workflow engines of related technologies, business data is divided into three categories: data in process, historical data, and effective data, and stored in three tables in the corresponding relational database of the system backend to achieve the recording and tracking of data changes. However, this method requires the construction of three isomorphic storage tables for each specific business scenario, and each set of tables for each scenario needs to be developed and coded separately, which is labor-intensive and inefficient. Summary of the Invention

[0004] This application provides a data processing method, apparatus, device, and medium for querying business data based on user-adjusted nodes, thereby improving data processing efficiency.

[0005] In a first aspect, embodiments of this application provide a data processing method, the method comprising:

[0006] In response to a user-triggered business request, determine the business data corresponding to the business request and determine the maximum baseline number corresponding to the business data;

[0007] Retrieve and display at least one piece of service information associated with the maximum baseline number from the memory, and receive service adjustment requests triggered by the user;

[0008] Based on the service adjustment request, at least one piece of service information associated with the maximum baseline number is retrieved from the memory;

[0009] A new baseline is created based on the at least one piece of business information, and at least one piece of business information in the new baseline is adjusted;

[0010] The baseline number of the new baseline is determined based on the maximum baseline number, and the baseline number of the new baseline is associated with the new baseline.

[0011] In this application, after a user triggers a business adjustment request, the method of adding a new baseline ensures that both the user's current adjustment operation and the current business data adjustment operation occur in the new baseline. This ensures that the current adjustment operation on the business data will not affect the historical data. Therefore, historical data and new data can be stored simultaneously. Users can view historical data through the baseline number, which improves data processing efficiency and is easy to develop and implement.

[0012] In some possible embodiments, after determining the business data corresponding to the business request in response to a user-triggered business request, the method further includes:

[0013] If the status of the business data is determined to be unsubmitted, then the business information corresponding to the business adjustment request is determined to be the first business information. The first business information is adjusted while keeping the version number associated with the first business information unchanged; wherein, the version number is used to represent the number of times the business information has been adjusted, and the first business information is the business information associated with the maximum baseline number; or,

[0014] If the status of the business data is determined to be unsubmitted, then the business information corresponding to the business adjustment request is determined to include first business information and second business information. The second business information is retrieved from the memory. The first business information and the second business information are adjusted. The maximum version number associated with the second business information is updated according to a preset method, while keeping the version number associated with the first business information unchanged. The second business information is the business information corresponding to the business adjustment request that does not belong to the business information associated with the maximum baseline number.

[0015] In this application, different maximum baseline numbers are set for business data in the unsubmitted state, depending on the type of business information, making the management of business data more flexible.

[0016] In some possible embodiments, the step of determining the service information corresponding to the service adjustment request is all first service information, and adjusting the first service information includes:

[0017] If the adjustment type is deletion, then the target business information to be deleted is determined from the first business information, and the target business information is deleted; or,

[0018] If the adjustment type is a modification type, then the target business information to be modified is determined from the first business information, and the target business information is modified.

[0019] In this application, business information is processed differently based on different business adjustment requests triggered by users, making the processing of business information more accurate.

[0020] In some possible embodiments, updating the maximum version number associated with the second business information according to a preset method includes:

[0021] The maximum version number of the second service information is increased by a step value to obtain the current maximum version number.

[0022] In this application, the new maximum version number is determined by increasing it in increments of a step value, which makes the management of business information more precise.

[0023] In some possible embodiments, after determining the business data corresponding to the business request in response to a user-triggered business request, the method further includes:

[0024] If the status of the business data is determined to be effective, then the effective baseline number corresponding to the business data is determined; the effective baseline number is the sequence number of the effective baseline corresponding to the business data.

[0025] Retrieve and display at least one piece of business information associated with the effective baseline number from the memory, and receive a service adjustment request triggered by the user;

[0026] Based on the service adjustment request, at least one piece of service information associated with the effective baseline number is retrieved from the memory;

[0027] A new baseline is created based on the at least one piece of business information, and at least one piece of business information in the new baseline is adjusted;

[0028] Obtain the effective baseline number of the business data corresponding to the business request, determine the baseline number of the new baseline based on the effective baseline number, and associate the baseline number of the new baseline with the new baseline.

[0029] In this application, for business data that has already taken effect, the business information to be displayed to the user is determined based on the effective baseline number, thus ensuring the accuracy of the business data display.

[0030] Secondly, this application provides a data processing apparatus, the apparatus comprising:

[0031] The business data determination module is used to determine the business data corresponding to the business request in response to a business request triggered by the user.

[0032] The maximum baseline number determination module is used to determine the maximum baseline number corresponding to the business data if the status of the business data is determined to be a submitted but not effective status.

[0033] The display module is used to retrieve and display at least one piece of business information associated with the maximum baseline number from the memory, and to receive service adjustment requests triggered by the user.

[0034] The business information acquisition module is used to acquire at least one piece of business information associated with the maximum baseline number from the memory based on the business adjustment request.

[0035] A baseline creation module is used to create a new baseline based on the at least one piece of business information, and to adjust at least one piece of business information in the new baseline;

[0036] The association module is used to determine the baseline number of the new baseline based on the maximum baseline number, and associate the baseline number of the new baseline with the new baseline.

[0037] In some possible embodiments, after the service data determination module executes a service request triggered by a user and determines the service data corresponding to the service request, the maximum baseline number determination module is further configured to:

[0038] If the status of the business data is determined to be unsubmitted, then the business information corresponding to the business adjustment request is determined to be the first business information. The first business information is adjusted while keeping the version number associated with the first business information unchanged; wherein, the version number is used to represent the number of times the business information has been adjusted, and the first business information is the business information associated with the maximum baseline number; or,

[0039] If the status of the business data is determined to be unsubmitted, then the business information corresponding to the business adjustment request is determined to include first business information and second business information. The second business information is retrieved from the memory. The first business information and the second business information are adjusted. The maximum version number associated with the second business information is updated according to a preset method, while keeping the version number associated with the first business information unchanged. The second business information is the business information corresponding to the business adjustment request that does not belong to the business information associated with the maximum baseline number.

[0040] In some possible embodiments, the maximum baseline number determination module determines that the service information corresponding to the service adjustment request is all first service information, and when adjusting the first service information, it is configured as follows:

[0041] If the adjustment type is deletion, then the target business information to be deleted is determined from the first business information, and the target business information is deleted; or,

[0042] If the adjustment type is a modification type, then the target business information to be modified is determined from the first business information, and the target business information is modified.

[0043] In some possible embodiments, when the maximum baseline number determination module updates the maximum version number associated with the second service information according to a preset method, it is configured as follows:

[0044] The maximum version number of the second service information is increased by a step value to obtain the current maximum version number.

[0045] In some possible embodiments, after the maximum baseline number determination module performs a response to a user-triggered service request and determines the service data corresponding to the service request, the maximum baseline number determination module is further configured to:

[0046] If the status of the business data is determined to be effective, then the effective baseline number corresponding to the business data is determined; the effective baseline number is the sequence number of the effective baseline corresponding to the business data.

[0047] Retrieve and display at least one piece of business information associated with the effective baseline number from the memory, and receive a service adjustment request triggered by the user;

[0063] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Unless otherwise specified, the embodiments and features in the embodiments of this application can be arbitrarily combined with each other. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than that shown here.

[0064] The terms "first" and "second" in the specification, claims, and accompanying drawings of this application are used to distinguish different objects, not to describe a specific order. Furthermore, the term "comprising" and any variations thereof are intended to cover non-exclusive protection. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or devices. The term "multiple" in this application can mean at least two, for example, two, three, or more, and the embodiments of this application do not impose limitations.

[0065] The data collection, dissemination, and use in this application all comply with relevant national laws and regulations.

[0066] Before introducing the data processing method provided in the embodiments of this application, for ease of understanding, the technical background of the embodiments of this application will be described in detail below.

[0067] The inventors discovered that in some workflow-based business approval systems, the approval data is edited and saved multiple times during the workflow process. Related technologies simply update and save the current data directly, failing to record the historical state of the business data or associate the business data snapshot with the approval process node at that time. Therefore, it is impossible to query the business data based on the approval history.

[0068] In addition, in workflow engines of related technologies, business data is divided into three categories: data in process, historical data, and effective data, and stored in three tables in the corresponding relational database of the system backend to achieve the recording and tracking of data changes. However, this method requires the construction of three isomorphic storage tables for each specific business scenario, and each set of tables for each scenario needs to be developed and coded separately, which is labor-intensive and inefficient.

[0069] The common technical approach in related technologies is to split a regular business entity table into three tables for storing process data, historical data, and effective data. This is to address the data storage and retrieval needs of the approval system at different times and in different scenarios. While this approach is easy for developers to understand and implement, it is not easy to maintain. The disadvantages of this approach are as follows:

[0070] 1) As business scenarios increase, the physical tables corresponding to the business entities are growing at a rate of three times, leading to increased operation and maintenance costs.

[0071] 2) When the data of the same business entity changes with the progress of the process, it involves linkage operations across three tables. For example, after the data approval is completed, the corresponding record needs to be deleted from the process table and added to the historical data table, and finally updated to the effective data table, which makes the processing efficiency of the business table low.

[0072] 3) Access to the same business entity data needs to be differentiated according to its status such as in progress, history, and currently active before it can be mapped to the corresponding physical table in the backend, which increases the development workload.

[0073] In view of this, this application proposes a data processing method, apparatus, electronic device, and storage medium to solve the above-mentioned problems. The inventive concept of this application can be summarized as follows: in response to a user-triggered service request, determining the service data corresponding to the service request and determining the maximum baseline number corresponding to the service data; retrieving and displaying at least one piece of service information associated with the maximum baseline number from a memory, and receiving a user-triggered service adjustment request; based on the service adjustment request, retrieving at least one piece of service information associated with the maximum baseline number from a memory; creating a new baseline based on at least one piece of service information and adjusting at least one piece of service information in the new baseline; determining the baseline number of the new baseline based on the maximum baseline number, and associating the baseline number of the new baseline with the new baseline.

[0074] For ease of understanding, the data processing method provided in this application embodiment will be described in detail below with reference to the accompanying drawings:

[0075] like Figure 1 The diagram shown illustrates an application scenario of a data processing method according to an embodiment of this application. The diagram includes: a server 10, a storage device 20, and a terminal device 30.

[0076] In response to a service request triggered by a user on terminal device 30, server 10 determines the service data corresponding to the service request; if the status of the service data is determined to be "submitted but not effective", it determines the maximum baseline number corresponding to the service data; it retrieves and displays at least one service information associated with the maximum baseline number from storage 20, and receives a service adjustment request triggered by the user; based on the service adjustment request, it retrieves at least one service information associated with the maximum baseline number from storage; it creates a new baseline based on at least one service information, and adjusts at least one service information in the new baseline; it determines the baseline number of the new baseline based on the maximum baseline number, and associates the baseline number of the new baseline with the new baseline.

[0077] The description in this application details only a single server, memory, and terminal device. However, those skilled in the art should understand that the illustrated servers, memory, and terminal devices are intended to illustrate the operation of the servers, memory, and terminal devices involved in the technical solutions of this application, and do not imply any limitation on the number, type, or location of the servers, memory, or terminal devices. It should be noted that adding additional modules to or removing individual modules from the illustrated environment will not change the underlying concept of the exemplary embodiments of this application. Furthermore, although for ease of explanation... Figure 1 The diagram shows a bidirectional arrow from memory 20 to server 10, but those skilled in the art will understand that the sending and receiving of the aforementioned data also needs to be achieved through a network.

[0078] It should be noted that the memory in the embodiments of this application can be, for example, a cache system, hard disk storage, memory storage, etc. Furthermore, the data processing method proposed in this application is not only applicable to… Figure 1 The application scenarios shown are also applicable to any device with data processing needs.

[0079] like Figure 2 The diagram shown is a schematic representation of the overall application flow of a data processing method provided in an embodiment of this application, wherein:

[0080] In step 201: In response to a user-triggered business request, determine the business data corresponding to the business request;

[0081] In step 202: If the status of the business data is determined to be "submitted but not effective", then determine the maximum baseline number corresponding to the business data;

[0082] In step 203: retrieve at least one service information associated with the maximum baseline number from the memory and display it; receive a service adjustment request triggered by the user.

[0083] In step 204: Based on the service adjustment request, retrieve at least one piece of service information associated with the maximum baseline number from the memory;

[0084] In step 205: a new baseline is created based on at least one piece of business information, and at least one piece of business information in the new baseline is adjusted;

[0085] In step 206: the baseline number of the new baseline is determined based on the maximum baseline number, and the baseline number of the new baseline is associated with the new baseline.

[0086] In this application, after a user triggers a business adjustment request, the method of adding a baseline ensures that historical data and new data can be stored simultaneously, and users can view historical data through the baseline number, thereby improving data processing efficiency.

[0087] For ease of understanding, the following is... Figure 2 The steps are explained in detail below:

[0088] First, the system framework of the data processing method in the embodiments of this application will be described: The data processing system provided in this application includes a data version storage standard, a data version control method, and a data version access interface. The system architecture is as follows: Figure 3As shown in this application, the data version storage standard is used to define a set of general data models and data structures for multi-version storage, record the state changes of data at different node units in the process, and support storage reuse in multiple scenarios; the data version control method is used to add and submit versions of data changes at different nodes in the business process, and at the same time establish the association between different versions of data and other business processes or business entities; the data version access interface is used to provide external systems or workflows with unified operation of business data and query and use of business data in different versions and states.

[0089] The definitions of the technical terms used in this application are explained below:

[0090] In this application, two elements, baseline and version, are added to the business data. The baseline records the state value of a group of related business entity models when they take effect at a certain process node, while the version records the state value of each business entity when it takes effect at a certain process node. The state values ​​of the baseline are collectively referred to as the baseline number, and the state values ​​of the version are collectively referred to as the version number. It is important to know that a group of related business entity models typically refers to a group of business entities with primary and foreign key dependencies. This model will have a primary entity, and other child entities will be additional attributes, with a one-to-one or one-to-many relationship with the primary entity.

[0091] In this application, different management methods are set up for business data in different states. The management methods for business data in different states are described below:

[0092] 1. Submitted but not yet effective

[0093] In this application, for business data that has been submitted but not yet taken effect, the following can be implemented: Figure 2 The steps shown are used to ensure that current data and historical data coexist in the memory by creating a new baseline.

[0094] For example: In response to a user-triggered business request, if the user wants to query business data A, and business data A is determined to be in a submitted but not yet effective state, then the maximum baseline number of business data A is retrieved from storage as 5. The business information associated with baseline number 5 of business data A in storage includes: business information 1, business information 2, and business information 3. Then, if... Figure 4 As shown, the system displays to the user the business information 1, business information 2, and business information 3 associated with baseline number 5 of business data A.

[0095] To ensure that users can view historical data in real time, it is necessary to ensure that historical data and the latest data of the business data exist in the memory at the same time after each user adjusts the business information. Therefore, in this application, if a business adjustment request triggered by the user is detected, the business information associated with baseline number 5 is obtained, and a new baseline is created based on the business information. The baseline number of the new baseline is 6. The business data is adjusted and saved based on the user's adjustment request. At this time, the business information associated with baseline 5 and baseline 6 exist in the memory at the same time.

[0096] In the embodiments of this application, the adjustment request can be to add business information, modify business information, or delete business information. Examples are given below:

[0097] 1) Add type

[0098] If the adjustment request triggered by the user is of the "add" type, then the service information with the highest version number for the target service information that the user wants to add is retrieved from the memory based on the service code of that service code. In this application, each piece of service information has a corresponding service code and version number, and the service information is globally unique.

[0099] For example, the business information associated with baseline number 5 includes: Business Information Version 1-1, Business Information Version 2-3, and Business Information Version 3-2. If a user wants to add Business Information 4, baseline number 6 is created based on baseline number 5. At this time, the business information under baseline number 6 includes: Business Information Version 1-1, Business Information Version 2-3, and Business Information Version 3-2. Based on the business code S of business information 4, the business information with business code S in the current memory is determined to be: Business Information 4-Version 1, Business Information 4-Version 2, and Business Information 4-Version 3. Then, business information 4-Version 3 is added to the new baseline. If the user does not modify other business information, the version numbers of business information 1, business information 2, and business information 3 under baseline number 6 remain unchanged, while the version number of business information 4 is changed from version 3 to version 4. That is, the maximum baseline number associated with business information A is baseline number 6, and the business information associated with baseline number 6 is business information version 1-1, business information version 2-3, business information version 3-2, and business information version 4-4.

[0100] 2) Deletion type

[0101] If the adjustment request triggered by the user is of the deletion type, then the target business information is determined from the business information in the maximum baseline number corresponding to the business data according to the adjustment request triggered by the user, and the target business information is deleted.

[0102] For example, baseline number 5 is associated with the following business information: Business Information Version 1-1, Business Information Version 2-3, and Business Information Version 3-2. If the user's adjustment request is a deletion request, baseline number 6 is created based on baseline number 5. At this point, the business information under baseline number 6 includes: Business Information Version 1-1, Business Information Version 2-3, and Business Information Version 3-2. Based on the user's adjustment request, the user wants to delete Business Information Version 1-1. Since the user has not modified any other business information, the version numbers of Business Information 2 and Business Information 3 under baseline number 6 remain unchanged, while Business Information Version 1-1 is deleted from baseline number 6. Therefore, the maximum baseline number associated with business information A is now baseline number 6, and the business information associated with baseline number 6 includes Business Information Versions 2-3 and 3-2.

[0103] 3) Modify type

[0104] If the adjustment request triggered by the user is of the modification type, then the target business information is determined from the business information in the maximum baseline number corresponding to the business data, and the target business information is modified according to the adjustment request triggered by the user.

[0105] For example, the business information associated with baseline number 5 includes: Business Information Version 1-1, Business Information Version 2-3, and Business Information Version 3-2. If the user's adjustment request is a modification type, then baseline number 6 is created based on baseline number 5. At this time, the business information under baseline number 6 includes: Business Information Version 1-1, Business Information Version 2-3, and Business Information Version 3-2. Based on the user's adjustment request, the business information that the user wants to modify is Business Information Version 1-1. Since the user has not modified other business information, the version numbers of Business Information 2 and Business Information 3 under baseline number 6 remain unchanged, while Business Information Version 1-1 is modified to Business Information Version 1-2. That is, at this time, the maximum baseline number associated with business information A is baseline number 6, and the business information associated with baseline number 6 is Business Information Version 1-2, Business Information Version 2-3, and Business Information Version 3-2.

[0106] It is important to know that users can modify, add, and delete business information under the maximum baseline number corresponding to the business data within a single adjustment. This application does not limit the number of adjustments triggered in a single business request; for example:

[0107] For example: Baseline number 5 is associated with the following business information: Business Information Version 1-1, Business Information Version 2-3, and Business Information Version 3-2. If the user's first adjustment request is a modification, then Baseline number 6 is created based on Baseline number 5. At this time, the business information under Baseline number 6 includes: Business Information Version 1-1, Business Information Version 2-3, and Business Information Version 3-2. Based on the user's adjustment request, the business information the user wants to modify is Business Information Version 1-1. Since the user has not modified other business information, the version numbers of Business Information 2 and Business Information 3 under Baseline number 6 remain unchanged, while Business Information Version 1-1 is modified to Business Information Version 1-2. Then, the user adjusts the business information again without submitting, and deletes Business Information 2-3. Therefore, Business Information 2-3 is deleted from Baseline number 6. Finally, the user adds Business Information Version 4-1 and submits. Therefore, the maximum baseline number associated with Business Information A is Baseline number 6, and the business information associated with Baseline number 6 includes Business Information Version 1-2, Business Information Version 3-2, and Business Information Version 4-1.

[0108] 2. Not submitted status

[0109] In this embodiment, if the status of the business data is determined to be "unsubmitted," it means that the user's adjustment operation on the business data has not yet ended, and therefore no new baseline will be added. The following descriptions are based on the type of business information and the response processing method:

[0110] 1) All business information is primary business information.

[0111] In some embodiments, if it is determined that the business information corresponding to the business adjustment request is all first business information, then the first business information is adjusted while keeping the version number associated with the first business information unchanged; wherein, the version number is used to represent the number of times the business information is adjusted, and the first business information is the business information associated with the maximum baseline number.

[0112] In this application, the adjustment types for the first business information include modification and deletion types, which are illustrated with examples below:

[0113] A. Modification Type

[0114] For example: A user is adjusting the business information associated with the maximum baseline number 5 corresponding to business data A. The business information associated with baseline number 5 includes: business information version 1-1, business information version 2-3, and business information version 3-2. The user wants to modify business information version 1-1. Based on the user's adjustment request, the target business information that the user wants to modify is determined to be business information version 1-1. Therefore, business information version 1-1 is modified based on the user's adjustment request. After the user's adjustment operation, the maximum baseline number corresponding to business data A is baseline 5, and the business information associated with baseline 5 includes: business information version 1-1, business information version 2-3, and business information version 3-2.

[0115] B. Deletion Type

[0116] For example: A user is adjusting the business information associated with the maximum baseline number 5 corresponding to business data A. The business information associated with baseline number 5 includes: business information version 1-1, business information version 2-3, and business information version 3-2. If the user wants to delete business information version 1-1, then based on the user's adjustment request, the target business information that the user wants to delete is determined to be business information version 1-1, and therefore business information version 1-1 is deleted from the business information associated with baseline 5. After the user's adjustment operation, the maximum baseline number corresponding to business data A is baseline 5, and the business information associated with baseline 5 includes: business information version 2-3 and business information version 3-2.

[0117] 2) Business information includes first business information and second business information.

[0118] If the status of the business data is determined to be unsubmitted, then the business information corresponding to the business adjustment request is determined to include first business information and second business information. The second business information is retrieved from the storage. The first business information and the second business information are adjusted. The maximum version number associated with the second business information is updated according to a preset method, while keeping the version number associated with the first business information unchanged. The second business information is the business information corresponding to the business adjustment request that does not belong to the business information associated with the maximum baseline number.

[0119] For example: A user is adjusting the business information associated with the maximum baseline number 5 corresponding to business data A. The business information associated with baseline number 5 includes: Business Information Version 1-1, Business Information Version 2-3, and Business Information Version 3-2. The user wants to adjust Business Information Version 4-1. It is determined that Business Information Version 4-1 is not currently associated with the business information of baseline 5. Therefore, Business Information Version 4-1 is the second business information. Based on the user's adjustment request, Business Information Version 4-1 is added to baseline 5 and modified to Business Information Version 4-2. After the user's adjustment operation, the maximum baseline number corresponding to business data A is baseline 5, and the business information associated with baseline 5 includes: Business Information Version 1-1, Business Information Version 2-3, Business Information Version 3-2, and Business Information Version 4-1.

[0120] 3. Status: Already in effect

[0121] In this application, each piece of business data that has taken effect has a corresponding effective baseline number, i.e., the sequence number of the effective baseline. However, the effective baseline number of this business data is not necessarily the maximum baseline number. For example, if the effective baseline number of business data A is 5, and the user adjusts the business data, the maximum baseline number of business data A becomes baseline 6, but the adjusted data may not yet be effective. Specific implementation details include... Figure 5 The steps shown are as follows:

[0122] In step 501: After responding to the business request triggered by the user and determining the business data corresponding to the business request;

[0123] In step 502: If the status of the business data is determined to be effective, then the effective baseline number corresponding to the business data is determined; the effective baseline number is the sequence number of the effective baseline corresponding to the business data.

[0124] In step 503: retrieve at least one service information associated with the effective baseline number from the memory and display it; receive a service adjustment request triggered by the user.

[0125] In step 504: Based on the service adjustment request, at least one piece of service information associated with the effective baseline number is retrieved from the memory;

[0126] In step 505: a new baseline is created based on at least one piece of business information, and at least one piece of business information in the new baseline is adjusted;

[0127] In step 506: obtain the effective baseline number of the business data corresponding to the business request, determine the baseline number of the new baseline based on the effective baseline number, and associate the baseline number of the new baseline with the new baseline.

[0128] For example: In response to a user-triggered business request, if it is determined that the business data the user wants to query is business data A, and that business data A is already in effect, then the effective baseline number of business data A is retrieved from the memory as 5. The business information associated with baseline number 5 of business data A in the memory is determined to include: business information 1, business information 2, and business information 3. Then, business information 1, business information 2, and business information 3 associated with baseline number 5 of business data A are displayed to the user.

[0129] If a user-triggered service adjustment request is detected, the service information associated with baseline number 5 is retrieved, and a new baseline is created based on this information. The new baseline has a baseline number of 6. The service data is adjusted and saved based on the user's adjustment request. At this point, the service information associated with both baseline 5 and baseline 6 exists in the memory. If baseline 6 is already in effect, the effective baseline number for service data A is 6; if baseline 6 is not in effect, the effective baseline number for service data A is 5, with a maximum baseline number of 6. After baseline 6 becomes effective, baseline 6 is used as the effective baseline number for service data A.

[0130] In the embodiments of this application, the adjustment request for business data that is already in effect can be to add business information, modify business information, or delete business information. Examples are given below:

[0131] 1) Add type

[0132] If the adjustment request triggered by the user is of the add type, then the service information with the largest version number of the target service information that the user wants to add is retrieved from the memory according to the service code of that service code.

[0133] For example: The business information associated with the effective baseline number 5 of business data A includes: Business Information Version 1-1, Business Information Version 2-3, and Business Information Version 3-2. If the user wants to add business information 4, a maximum baseline number 6 is created based on the effective baseline number 5. At this time, the business information under baseline number 6 includes: Business Information Version 1-1, Business Information Version 2-3, and Business Information Version 3-2. Based on the business code S of business information 4, the business information with business code S in the current storage is determined to be: Business Information 4-Version 1, Business Information 4-Version 2, and Business Information 4-Version 3. Then, business information 4-Version 3 is added to the new baseline. If the user does not modify other business information, the version numbers of business information 1, business information 2, and business information 3 under baseline number 6 remain unchanged, while the version number of business information 4 is changed from version 3 to version 4. That is, the maximum baseline number associated with business information A is baseline number 6, and the business information associated with baseline number 6 is business information version 1-1, business information version 2-3, business information version 3-2, and business information version 4-4. After baseline number 6 takes effect, it will be associated with the effective baseline number of business data A.

[0134] 2) Deletion type

[0135] If the adjustment request triggered by the user is of the deletion type, then the target business information is determined from the business information in the maximum baseline number corresponding to the business data according to the adjustment request triggered by the user, and the target business information is deleted.

[0136] For example, the business information associated with effective baseline number 5 includes: Business Information Version 1-1, Business Information Version 2-3, and Business Information Version 3-2. If the user triggers an adjustment request of type deletion, baseline number 6 is created based on effective baseline number 5. At this time, the business information under baseline number 6 includes: Business Information Version 1-1, Business Information Version 2-3, and Business Information Version 3-2. Based on the user's adjustment request, the business information the user wants to delete is Business Information Version 1-1. Since the user has not modified other business information, the version numbers of Business Information 2 and Business Information 3 under baseline number 6 remain unchanged, while Business Information Version 1-1 is deleted from baseline number 6. That is, at this time, the maximum baseline number associated with business information A is baseline number 6, and the business information associated with the maximum baseline number 6 is Business Information Version 2-3 and Business Information Version 3-2. After baseline number 6 takes effect, it is associated with the effective baseline number of business data A.

[0137] 3) Modify type

[0138] If the adjustment request triggered by the user is of the modification type, then the target business information is determined from the business information in the maximum baseline number corresponding to the business data, and the target business information is modified according to the adjustment request triggered by the user.

[0139] For example, the business information associated with effective baseline number 5 includes: Business Information Version 1-1, Business Information Version 2-3, and Business Information Version 3-2. If the user-triggered adjustment request is a modification type, baseline number 6 is created based on effective baseline number 5. At this time, the business information under baseline number 6 includes: Business Information Version 1-1, Business Information Version 2-3, and Business Information Version 3-2. Based on the user's adjustment request, the business information the user wants to modify is Business Information Version 1-1. Since the user has not modified other business information, the version numbers of Business Information 2 and Business Information 3 under baseline number 6 remain unchanged, while Business Information Version 1-1 is modified to Business Information Version 1-2. That is, the maximum baseline number associated with business information A is baseline number 6, and the business information associated with baseline number 6 is Business Information Version 1-2, Business Information Version 2-3, and Business Information Version 3-2. After baseline number 6 takes effect, it is associated with the effective baseline number of business data A.

[0140] It is important to know that users can modify, add, and delete business information under the effective baseline number corresponding to the business data in a single adjustment. This application does not limit the number of adjustments triggered in a single business request; for example:

[0141] For example: the business information associated with effective baseline number 5 includes: Business Information Version 1-1, Business Information Version 2-3, and Business Information Version 3-2. If the user's first adjustment request is a modification type, baseline number 6 is created based on effective baseline number 5. At this time, the business information under baseline number 6 includes: Business Information Version 1-1, Business Information Version 2-3, and Business Information Version 3-2. Based on the user's adjustment request, the business information the user wants to modify is Business Information Version 1-1. Since the user has not modified other business information, the version numbers of Business Information 2 and Business Information 3 under baseline number 6 remain unchanged, while Business Information Version 1-1 is modified to Business Information Version 1-2. Then, the user adjusts the business information again without submitting and deletes Business Information 2-3. Therefore, Business Information 2-3 is deleted from baseline number 6. Finally, the user adds Business Information Version 4-1 and submits. Therefore, the maximum baseline number associated with business information A is baseline number 6, and the business information associated with baseline number 6 includes Business Information Version 1-2, Business Information Version 3-2, and Business Information Version 4-1. After baseline number 6 takes effect, it will be associated with the effective baseline number of business data A.

[0142] In the above data processing method, the determination of the new baseline number and the new version number are incremented by a step value. It should be noted that technicians can set the step value according to their needs, and this application does not limit this.

[0143] like Figure 6 As shown, based on the same inventive concept, a data processing device 600 is proposed, the device comprising:

[0144] The business data determination module 6001 is used to determine the business data corresponding to the business request in response to a business request triggered by the user.

[0145] The maximum baseline number determination module 6002 is used to determine the maximum baseline number corresponding to the business data if the status of the business data is determined to be a submitted but not effective status.

[0146] The display module 6003 is used to retrieve and display at least one service information associated with the maximum baseline number from the memory, and to receive service adjustment requests triggered by the user.

[0147] The business information acquisition module 6004 is used to acquire at least one piece of business information associated with the maximum baseline number from the memory based on the business adjustment request.

[0148] The baseline creation module 6005 is used to create a new baseline based on the at least one piece of business information, and to adjust at least one piece of business information in the new baseline;

[0149] The association module 6006 is used to determine the baseline number of the new baseline based on the maximum baseline number, and associate the baseline number of the new baseline with the new baseline.

[0150] In some possible embodiments, after the service data determination module executes a service request triggered by a user and determines the service data corresponding to the service request, the maximum baseline number determination module is further configured to:

[0151] If the status of the business data is determined to be unsubmitted, then the business information corresponding to the business adjustment request is determined to be the first business information. The first business information is adjusted while keeping the version number associated with the first business information unchanged; wherein, the version number is used to represent the number of times the business information has been adjusted, and the first business information is the business information associated with the maximum baseline number; or,

[0152] If the status of the business data is determined to be unsubmitted, then the business information corresponding to the business adjustment request is determined to include first business information and second business information. The second business information is retrieved from the memory. The first business information and the second business information are adjusted. The maximum version number associated with the second business information is updated according to a preset method, while keeping the version number associated with the first business information unchanged. The second business information is the business information corresponding to the business adjustment request that does not belong to the business information associated with the maximum baseline number.

[0153] In some possible embodiments, the maximum baseline number determination module determines that the service information corresponding to the service adjustment request is all first service information, and when adjusting the first service information, it is configured as follows:

[0154] If the adjustment type is deletion, then the target business information to be deleted is determined from the first business information, and the target business information is deleted; or,

[0155] If the adjustment type is a modification type, then the target business information to be modified is determined from the first business information, and the target business information is modified.

[0156] In some possible embodiments, when the maximum baseline number determination module updates the maximum version number associated with the second service information according to a preset method, it is configured as follows:

[0157] The maximum version number of the second service information is increased by a step value to obtain the current maximum version number.

[0158] In some possible embodiments, after the maximum baseline number determination module performs a response to a user-triggered service request and determines the service data corresponding to the service request, the maximum baseline number determination module is further configured to:

[0159] If the status of the business data is determined to be effective, then the effective baseline number corresponding to the business data is determined; the effective baseline number is the sequence number of the effective baseline corresponding to the business data.

[0160] Retrieve and display at least one piece of business information associated with the effective baseline number from the memory, and receive a service adjustment request triggered by the user;

[0161] Based on the service adjustment request, at least one piece of service information associated with the effective baseline number is retrieved from the memory;

[0162] A new baseline is created based on the at least one piece of business information, and at least one piece of business information in the new baseline is adjusted;

[0163] Obtain the effective baseline number of the business data corresponding to the business request, determine the baseline number of the new baseline based on the effective baseline number, and associate the baseline number of the new baseline with the new baseline.
