[0042] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0043] like Figure 1 The flowchart of a questionnaire generation method proposed in an embodiment of the present invention is shown, and the method includes:

[0044] S201, creating a periodic quota table based on the original quota group table, quota condition table, and quota checkpoint table.

[0045] Specifically, the original quota group table (named: qdes_quota), the original quota condition table (named: survey_quotacondition), and the original quota checkpoint table (named: survey_quotacheckitem) are set first, and a periodic quota table (named: qdes_quotaround) is created in the original quota group table, quota condition table, and quota checkpoint table. The fields in the periodic quota table include round_type (quota type), enumeration type, natural day day, natural week week, natural month month, custom custom, quota_id (ID of the configuration group table), name (name of this period), for example: 2021-13W means the 13th week of 2021, start_at (cycle start time), end_at (cycle end time), quota_cond_list (quota condition table ID list), quota_checkitem_list (quota checkpoint table ID list).

[0046] In order to set different quota amounts for different periods, in a preferred embodiment of this solution, after creating a periodic quota table based on the original quota group table, quota condition table, and quota checkpoint table, it also includes: adding the quota group table field and quota condition table field.

[0047] Specifically, new quota group table fields and quota condition table fields have been added. The new fields in the quota group qdes_quota table are as follows: (1).is_round (whether it is a periodic quota), enumeration type. This application is compatible with the original quota. There is no situation where 0 indicates a general quota and 1 indicates a periodic quota; (2).round_type (quota type), redundant field, enumeration type, natural day day, natural week week, natural month month, custom custom. The new fields in the quota condition table are as follows: (1).is_round, redundant field; (2).round_type, redundant field; (3).start_at (period start time), redundant field; (4).end_at (period end time), redundant field; (5).ID of the quota period table. The design of redundant fields is conducive to reducing database operations, the probability of exchanging space for time, improving system performance, and making the user experience stronger.

[0048] S202: When the user's option information is obtained to set a period quota, corresponding period quota table data is generated according to the set period number.

[0049] Specifically, Figure 2 The following is a page display diagram for setting periodic quotas. It supports setting quotas within a time period, and this time period supports natural days, natural weeks, natural months, and custom time periods. When the user chooses to set a periodic quota, the corresponding periodic quota table data is generated according to the number of periods set. Each period corresponds to a data record. Batch generation of records can reduce the number of database operations and improve performance. At the same time, the quota group table stores more is_round and round_type information when updating.

[0050] S203: Based on the periodic quota table data, batch generate data records corresponding to each period, wherein the data records include quota condition table records and quota checkpoint table records.

[0051] Specifically, Figure 3The figure shows the effect after the periodic quota is set. When the user chooses to set it as a periodic quota, the corresponding periodic quota table data is generated according to the set number of periods. Each period corresponds to a data record, and the records are generated in batches. According to the newly generated periodic quota table record, the following data records are generated: (1). There are one or more quota condition table records; (2). There are one or more quota checkpoint table records. Since this application supports ordinary quotas and cross quotas, and can support the situation where there is no upper limit on the number of periods, different quota amounts are set for different periods, which can provide users with more flexible usage scenarios. It should be noted that the rules for generating data records are the same as those for using general quotas. When setting periodic quotas, the following data is generated once for each period, and batch operations are used to improve performance and function availability.

[0052] In order to meet more research needs of users and make subsequent analysis results more accurate, the preferred embodiment of this solution also includes:

[0053] When the periodic quota is added, periodic quota table data, quota condition table data, quota checkpoint table data are created, and the status and type of the corresponding quota record period in the quota group table are updated;

[0054] When modifying the periodic quota, new periodic quota table data, quota condition table data, and quota checkpoint table data are created and the original corresponding data are deleted, and the status and type of the recording period of the corresponding quota in the quota group table are updated;

[0055] When deleting the periodic quota, the corresponding periodic quota table data, quota condition table data, and quota checkpoint table data are deleted, and the status and type of the recording period of the corresponding quota in the quota group table are updated.

[0056] Specifically, the business logic can be adjusted to meet different scenarios and better handle the intentions of different customers in different time periods in reality, and be more flexible in application. An interface is used to create, modify, and delete periodic quotas. If you want to add periodic quotas on the basis of the original ones, create periodic quota table data, quota condition table data, quota checkpoint table data, and update the status and type of the corresponding quota record period in the quota group table; if you want to modify periodic quotas, create new periodic quota table data, quota condition table data, quota checkpoint table data, delete the old corresponding data, and update the status and type of the corresponding quota record period in the quota group table; if you delete periodic quotas, delete the corresponding periodic quota table data, quota condition table data, quota checkpoint table data, and update the status and type of the corresponding quota record period in the quota group table. Business adjustments also include: 1. When modifying quota checkpoints, if it is a periodic quota, the checkpoint information stored in the quota condition table corresponding to other periods needs to be synchronized; 2. When deleting a quota, delete the corresponding periodic data and quota condition data and quota detection option data, and delete the quota data (add and delete periodic data on a general basis, and other general data will be deleted together); 3. When deleting quota options, if it is a periodic quota, the option data in other periods will be deleted synchronously, and the corresponding information stored in quota_cond_list and quota_checkitem_list in the period will be updated; 4. When adding options, if it is a periodic quota, the option data in other periods will be added synchronously, and the corresponding information stored in quota_cond_list and quota_checkitem_list in the period will be updated. The above operations to adjust the business logic require updating the quota progress. No matter which periodic quota it is, as long as there is a change, a message will be sent to update the quota progress, and the progress will be cached, so that the page display can achieve real-time update effect.

[0057] Refresh quota progress and refresh quota progress cache in real time to facilitate the call and display of quota progress data.

[0058] In order to verify the quota, in a preferred embodiment of this solution, the following is also included:

[0059] When answering questions to verify the quota, a check and judgment is performed according to the period corresponding to the quota and the quota progress is refreshed, and the quota progress is cached so as to be displayed on the terminal page.

[0060] Specifically, when answering questions to verify the quota, if there is a periodic quota, the verification and judgment will be performed according to the corresponding period, other services remain unchanged, and then the quota progress will continue to be refreshed, and the quota progress will be cached, so that real-time update effect can be achieved on the page display.

[0061] In order to realize the batch download quota progress, in the preferred embodiment of this scheme, it also includes:

[0062] When downloading quota progress in batches, if it is a periodic quota, obtain the corresponding period ID, search for the quota progress information of this period, and download it.

[0063] It should be noted that the technical implementation method of the periodic quota adopts the redis_memorize cache mechanism. Redis is actually a key-value database, but it also has some advantages of a relational database. Specifically, in the embodiment of the present application, through the redis_memorize technology, most of the quota progress data and periodic data can be read from the cache, reducing the quota progress calculation time and speeding up the web page response time.

[0064] S204: Generate a questionnaire based on the periodic quota table, the quota condition table records, and the quota checkpoint table records.

[0065] The present invention discloses a questionnaire generation method, the method comprising: creating a periodic quota table based on an original quota group table, a quota condition table, and a quota checkpoint table; when the user's option information is obtained to set a periodic quota, generating corresponding periodic quota table data according to the set number of periods; based on the periodic quota table data, batch generating data records corresponding to each period, the data records including quota condition table records and quota checkpoint table records. The periodic quota of the present application supports setting a quota amount within a time period, and this time period supports natural days, natural weeks, natural months, and custom time periods, so that it can better handle the intended selection of different customers in different time periods in reality, realize more flexible applications, make the collected data samples more targeted, and make the later analysis results of the questionnaire survey more accurate. It can meet more research needs of users and make the subsequent analysis results more accurate.

[0066] In order to further explain the technical idea of ​​the present invention, the technical solution of the present invention is now described in combination with specific application scenarios.

[0067] First, set the original quota group table, the original quota condition table, and the original quota checkpoint table, and create a periodic quota table in the original quota group table, quota condition table, and quota checkpoint table. The fields in the periodic quota table include round_type (quota type), enumeration type, natural day day, natural week week, natural month month, custom custom, quota_id (configuration group table ID), name (name of this cycle), end_at (end time of the cycle), quota_cond_list (quota condition table ID list), quota_checkitem_list (quota checkpoint table ID list).

[0068] This application has designed a periodic quota, including fixed periods such as natural days, natural weeks, and natural months. It can also set periods with different time spans, which can be flexibly used in various practical scenarios and use time and space to meet various needs. At the same time, the independence of periodic probability is achieved, which is well guaranteed in terms of portability and scalability, and can better adapt to future expansion. By using batch operation databases, a large number of database operation instructions are reduced, a large amount of database pressure is reduced, and the performance of system functions is guaranteed.

[0069] New quota group table fields and quota condition table fields have been added. The new fields in the quota group qdes_quota table are as follows: (1).is_round (whether it is a periodic quota), enumeration type. This application is compatible with the original quota. There is no situation where 0 indicates a general quota and 1 indicates a periodic quota; (2).round_type (quota type), redundant field, enumeration type, natural day day, natural week week, natural month month, custom. The new fields in the quota condition table are as follows: (1).is_round, redundant field; (2).round_type, redundant field; (3).start_at (period start time), redundant field; (4).end_at (period end time), redundant field; (5).ID of the quota period table. When the user chooses to set it as a periodic quota, the corresponding periodic quota table data is generated according to the number of periods set. Each period corresponds to a data record, and records are generated in batches. According to the newly generated periodic quota table record, the following data records are generated: (1) There are one or more quota condition table records; (2) There are one or more quota checkpoint table records. Since this application supports normal quotas and cross quotas, and can support the situation where there is no upper limit on the number of periods, it is possible to set different quota amounts for different periods, which can provide users with more flexible usage scenarios.

[0070] The business logic can be adjusted to meet different scenarios and better handle the intentions of different customers in different time periods in reality, and be more flexible in application. An interface is used to create, modify and delete periodic quotas. If you want to add periodic quotas on the basis of the original ones, create periodic quota table data, quota condition table data, quota checkpoint table data, and update the status and type of the corresponding quota record period in the quota group table; if you want to modify periodic quotas, create new periodic quota table data, quota condition table data, quota checkpoint table data, delete the old corresponding data, and update the status and type of the corresponding quota record period in the quota group table; if you delete periodic quotas, delete the corresponding periodic quota table data, quota condition table data, quota checkpoint table data, and update the status and type of the corresponding quota record period in the quota group table. Business adjustments also include: 1. When modifying quota checkpoints, if it is a periodic quota, the checkpoint information stored in the quota condition table corresponding to other periods needs to be synchronized; 2. When deleting a quota, delete the corresponding periodic data and quota condition data and quota detection option data, and delete the quota data (add and delete periodic data on a general basis, and other general data will be deleted together); 3. When deleting quota options, if it is a periodic quota, the option data in other periods will be deleted synchronously, and the corresponding information stored in quota_cond_list and quota_checkitem_list in the period will be updated; 4. When adding options, if it is a periodic quota, the option data in other periods will be added synchronously, and the corresponding information stored in quota_cond_list and quota_checkitem_list in the period will be updated. The above operations to adjust the business logic require updating the quota progress. No matter which periodic quota it is, as long as there is a change, a message will be sent to update the quota progress, and the progress will be cached, so that the page display can achieve real-time update effect. When the user needs to answer questions to verify the quota, if there is a periodic quota, the verification is performed according to the corresponding period, other services remain unchanged, and then the quota progress cache is refreshed. If the quota progress needs to be downloaded in batches, if it is a periodic quota, the corresponding period ID is obtained, the quota progress information of this period is searched, and downloaded.

[0071] In order to achieve the above technical objectives, the present application embodiment also proposes a questionnaire generation system, such as Figure 4 As shown, the system comprises:

[0072] A creation module 401 is used to create a periodic quota table based on the original quota group table, quota condition table, and quota checkpoint table;
