Description

Technical Field

[0001] The present application relates to the field of data processing technology, and in particular to a collection data updating method and related devices. Background Art

[0002] As the number of people using credit cards continues to expand, the number of people who are overdue for credit card repayments is also gradually increasing. The bank's core system sends the current overdue credit card account information, basic information of overdue credit cards, and other supporting information to the collection system every day. The collection system updates the historical collection data in the system based on the received information to obtain the latest collection data for subsequent collection work.

[0003] The collection data updating method may include: the collection system obtains incremental credit card basic information and collection account information from the core system, updates the full credit card basic information in the system according to the incremental credit card basic information, and obtains the latest full credit card basic information; and then updates the historical collection data in the system according to the obtained collection account information and the latest full credit card basic information, and obtains the latest collection data. However, the collection data updating method is inefficient and cannot generate the latest collection data in a timely manner.

[0004] Therefore, how to improve the updating efficiency of collection data has become an urgent problem to be solved. Summary of the invention

[0005] The present application provides a collection data updating method and related devices, which improve the updating efficiency of collection data.

[0006] In a first aspect, the present application provides a method for updating collection data, which is executed by a collection system, and the method includes: obtaining incremental credit card basic data and overdue credit card account data; extracting to-be-updated collection data from the full credit card basic data based on the overdue credit card account data, wherein the full credit card basic data includes credit card account data, and the to-be-updated collection data includes credit card basic data corresponding to the credit card account data in the full credit card basic data that is the same as the overdue credit card account data; updating the to-be-updated collection data based on the incremental credit card basic data to obtain the collection data.

[0007] In this method, the collection system extracts the collection data to be updated from the full amount of credit card basic data in the system according to the latest overdue credit card account data obtained, and then updates the collection data to be updated according to the acquired incremental credit card basic data to obtain the latest collection data. Compared with first updating the full amount of credit card basic data in the system according to the acquired incremental credit card basic information to obtain the latest full amount of credit card basic data, and then extracting the latest collection data from the latest full amount of credit card basic information according to the acquired latest overdue credit card account data, this method adopts a method of separating the collection data update and the credit card basic data update, avoiding the update of the collection data by updating the full amount of credit card basic data, shortening the collection data update time, and improving the collection data update efficiency.

[0008] In one possible implementation, the method further includes: establishing a collection information table sub-table based on the collection information table in the collection system, the collection information table including historical collection data, the historical collection data in the collection information table sub-table being consistent with the historical collection data in the collection information table; and updating the historical collection data in the collection information table sub-table based on the collection data to obtain an updated collection information table sub-table.

[0009] In this implementation, the latest collection data is updated to the collection information table sub-table. Compared with directly updating the latest collection data to the collection information table main table, this solves the problem that the collection information table main table cannot perform batch collection data updates during online business, and improves the update efficiency of the collection information table.

[0010] In one possible implementation, the method further includes: receiving query request information, wherein the query request information is used to request a query for one or more pieces of data in the collection data; querying the one or more pieces of data from the updated collection information table sub-table according to the query request information; updating the historical collection data in the collection information table according to the one or more pieces of data; and marking the one or more pieces of data in the collection information table sub-table as updated.

[0011] In this implementation, the collection system queries the required collection data from the collection information table sub-table according to the received query request information, and updates the collection information table main table according to the queried collection data. This avoids the situation of locking the table and blocking the online business caused by updating the collection information table main table according to the large amount of collection data in the updated collection information table sub-table, thereby improving the updating efficiency of the collection information table.

[0012] In a second aspect, the present application provides a device for updating collection data, the device comprising: an acquisition module for acquiring incremental credit card basic data and overdue credit card account data; an extraction module for extracting to-be-updated collection data from the full amount of credit card basic data based on the overdue credit card account data, the full amount of credit card basic data including credit card account data, the to-be-updated collection data including credit card basic data corresponding to the credit card account data identical to the overdue credit card account data in the full amount of credit card basic data; an update module for updating the to-be-updated collection data based on the incremental credit card basic data to obtain the collection data.

[0013] In one possible implementation, the device also includes an establishment module, which is used to establish a collection information table sub-table based on the collection information table in the collection system, wherein the collection information table includes historical collection data, and the historical collection data in the collection information table sub-table is consistent with the historical collection data in the collection information table; the update module is also used to update the historical collection data in the collection information table sub-table based on the collection data to obtain an updated collection information table sub-table.

[0014] In a possible implementation, the device also includes a receiving module, a query module and a marking module; the receiving module is used to receive query request information, and the query request information is used to request a query for one or more pieces of data in the collection data; the query module is used to query the one or more pieces of data from the updated collection information table sub-table according to the query request information; the update module is also used to update the historical collection data in the collection information table according to the one or more pieces of data; the marking module is used to mark the one or more pieces of data in the collection information table sub-table as updated.

[0015] The beneficial effects of the second aspect and various possible implementations of the second aspect can be found in the beneficial effects of the first aspect and various possible implementations of the first aspect, and will not be repeated here.

[0029] The following will describe the technical solutions in the embodiments of the present application in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0030] To facilitate understanding, some concepts involved in the embodiments of the present application are first explained.

[0031] Intermediate table: refers to a physical database table used for temporary transition. It can be deleted directly after use and rebuilt the next time it is used; it can also be retained after use and the current data can be cleared and reused the next time it is used.

[0032] Hot table: refers to a frequently used database table. Because it always remains popular, it is referred to as a hot table.

[0033] Sub-table: refers to a copy of the original table, which is used to replace the original table to perform some processing functions.

[0034] Table lock / table lock: refers to a write protection mechanism based on the database. When the database table records are modified more than a certain proportion at one time, they are exclusively locked.

[0035] Index: refers to a structure that sorts the values ​​of one or more columns in a database table. Indexes can be used to quickly access specific information in the database table.

[0036] Figure 1 FIG. 1 is a schematic diagram of a system architecture of an embodiment of the present application. Figure 1 As shown, the banking system 100 includes a core system 110 and a collection system 120 .

[0037] The core system 110 is used to collect daily incremental credit card basic information and current overdue credit card account information, and push the collected incremental credit card basic information and current overdue credit card account information to a designated address within a preset period of time. For example, the credit card basic information may include credit card account information and customer information corresponding to the credit card account.

[0038] The collection system 120 is used to update the full amount of credit card basic information and historical collection data within the collection system 120 according to the daily incremental credit card basic information and current overdue credit card account information pushed by the core system 110, and obtain the latest full amount of credit card basic information and collection data.

[0039] Understandably, Figure 1The system architecture shown is only an example of the banking system provided by the present application. In other embodiments of the present application, the banking system 100 may include more or fewer components than shown in the figure, or combine some components, or split some components, or arrange the components differently. The components shown in the figure may be implemented in hardware, software, or a combination of software and hardware, which is not limited in the present application.

[0040] Normally, the core system pushes the previous day's incremental credit card basic data and overdue credit card account data to the designated address between 4 and 5 a.m. Considering that data synchronization between the core system and the collection system requires a long execution time, in order to avoid affecting the online transactions in the bank system starting at 8 a.m., the batch data synchronization operation between the core system and the collection system will not be executed until 18:00. This will cause a large delay in the update of the full amount of credit card basic information and collection data in the collection system. In the actual collection process, the probability that the credit card user has already paid back but is still being collected increases, resulting in an increase in customer complaints. Therefore, it is necessary to shorten the data delay time when performing data synchronization operations between the core system and the collection system, thereby improving the update efficiency of the collection data in the collection system.

[0041] Based on the above problems, improvement plans have been proposed for both the core system and the collection system. For example, the improvement plans proposed for the core system include: ⑴ Adjust the execution time point of the batch program corresponding to the incremental credit card basic data and the current overdue credit card account data, and advance the execution time point of the batch program corresponding to the incremental credit card basic data and the current overdue credit card account data; ⑵ Optimize the performance of the core system and shorten the execution time of the batch program corresponding to the incremental credit card basic data and the current overdue credit card account data. The improvement plans proposed for the collection system include: ⑴ Optimize the index of the database table to which the credit card basic data and the collection data belong in the collection system, and shorten the time of data synchronization operations by improving the execution efficiency of data synchronization operations; ⑵ Separate different batch programs, and give priority to executing batch programs to which data with higher timeliness requirements belong. For example, if the timeliness requirements for overdue credit card account data are higher, the batch program to which the overdue credit card account data belongs will be executed first.

[0042] Although the above-mentioned improvement schemes can theoretically solve the problems such as data delay that occur during the data synchronization process between the current core system and the collection system, they have the following limitations and shortcomings: First, the execution order of the batch program of the core system has its inherent logic and may not be adjustable; second, the core system and the collection system have been optimized many times, and there is no room for significant optimization in performance; third, the amount of incremental credit card basic data and overdue credit card account data that the core system needs to push on large billing days will increase greatly, and the execution time of the core system and the collection system will be greatly extended, which may cause the collection system to fail to receive the data file containing the incremental credit card basic data and overdue credit card account data on time and report an error, or because the execution time of the collection system is too long, affecting the online business of the bank system; finally, the above-mentioned improvement scheme has very high requirements for nodes and no fault tolerance. Once a special situation occurs in the core system, the collection system will inevitably fail.

[0043] Therefore, the above-mentioned improvement method cannot effectively solve the problem of data delay when performing data synchronization operations between the core system and the collection system, and thus cannot improve the updating efficiency of the collection data in the collection system.

[0044] Figure 2 FIG. 1 is a flowchart of a method for updating collection data. Figure 2 As shown, the method at least includes S201 to S204. The method is executed by a collection system, which can be Figure 1 The collection system in 120.

[0045] S201, the collection system obtains the latest incremental credit card basic information and overdue credit card account information from the core system.

[0046] As an example, the core system could be Figure 1 The core system 110 in.

[0047] S202, updating the full amount of credit card basic information in the system according to the incremental credit card basic information to obtain the latest full amount of credit card basic information.

[0048] S203, updating the historical collection data in the system according to the acquired overdue credit card account information and the latest full credit card basic information to obtain the latest collection data.

[0049] S204, updating the collection information table according to the latest collection data to obtain the latest collection information table.

[0050] According to statistics, the collection system stores billions of basic credit card information, the daily incremental basic credit card information is about five million, and the daily overdue credit card account information is about one million. Figure 2The collection data updating method shown in the figure first updates the basic information of all credit cards in the collection system of 100 million levels according to the acquired incremental basic credit card data of about 5 million levels, and then updates the historical collection data according to the updated basic information of all credit cards of 100 million levels and the overdue credit card account information of about 1 million levels to obtain the latest collection data. The amount of data updated in this method is large, so that the updating process of the collection data takes a long time, and the latest collection data cannot be obtained in time; in addition, Figure 2 In the method shown, the main table of the collection information table is directly updated according to the updated collection data, which has the risk of affecting the online business.

[0051] To solve Figure 2 In order to solve the problem in the above application, the present application proposes the following technical solution: the collection system first extracts about one million collection data to be updated from the full amount of credit card basic information of 100 million based on the received overdue credit card account information of about one million, and then updates the about one million collection data to be updated based on the acquired incremental credit card basic information of about five million to obtain the latest collection data; and, updates the collection information table sub-table based on the latest collection data to obtain the latest collection information table sub-table, and completes the collection data query business based on the latest collection information table sub-table, thereby improving the updating efficiency of the collection data and avoiding the problem that the data updating business and the online business cannot be carried out synchronously due to the direct updating of the main table of the collection information table.

[0052] Figure 3 FIG. 1 is a flow chart of a method for updating collection data according to an embodiment of the present application. Figure 3 As shown, the method at least includes S301 to S303. The method is executed by a collection system, which can be Figure 1 The collection system in 120.

[0053] S301, obtaining incremental credit card basic data and overdue credit card account data.

[0054] In one possible implementation, the collection system obtains the latest incremental credit card basic data and overdue information card account data from the core system in the form of data files, and imports the obtained incremental credit card basic data and overdue credit card account data into the corresponding intermediate table.

[0055] As an example, the core system pushes a data file containing the latest incremental credit card basic data and overdue information card account data to the designated address before 5 a.m. The collection system starts to obtain the data file at 7 o'clock and imports the incremental credit card basic data and overdue information card account data in the data file into the corresponding intermediate table in sequence.

[0056] Exemplarily, the core system may be Figure 1 The core system 110 in.

[0057] Exemplarily, the collection system imports the acquired incremental credit card basic information into the card account customer intermediate table.

[0058] Exemplarily, the collection system imports the acquired overdue credit card account data into the intermediate table of collection account information.

[0059] S302, extracting the collection data to be updated from the full amount of credit card basic data based on the overdue credit card account data, the full amount of credit card basic data including the credit card account data, and the collection data to be updated includes the credit card basic data corresponding to the credit card account data that is the same as the overdue credit card account data in the full amount of credit card basic data.

[0060] In one possible implementation, the collection system extracts the credit card basic data corresponding to the credit card account data that is the same as the overdue credit card account data from the local full credit card basic data as the collection data to be updated, and imports the extracted collection data to be updated into the corresponding intermediate table.

[0061] As an example, the collection system queries the basic data of millions of credit cards under collection from the local full card account customer data table that has not been updated based on the latest overdue credit card account data in the intermediate table of information on accounts under collection, that is, the collection data to be updated, and imports it into the intermediate table of basic information on credit cards under collection.

[0062] S303, updating the collection data to be updated according to the incremental credit card basic data to obtain the collection data.

[0063] In a possible implementation, the collection system updates the to-be-updated collection data in the collection account information intermediate table according to the acquired incremental credit card basic data to obtain the latest collection data.

[0064] In one possible implementation, the collection system establishes a collection information table sub-table based on the collection information table in the system. The collection information table includes historical collection data. The historical collection data in the collection information table sub-table is consistent with the historical collection data in the collection information table. The historical collection data in the collection information table sub-table is updated according to the latest collection data to obtain an updated collection information table sub-table. The collection data in the updated collection information table sub-table is the latest collection data for use in certain special transaction queries that are sensitive to the timeliness of basic customer information.

[0065] Since the latest collection data is only updated to the collection information table sub-table, and the collection information table sub-table is only used for querying some special transactions, in order to enable all other related transactions to obtain the latest collection data, the collection data in the collection information table main table for all transactions needs to be updated to the latest data. However, for online hot tables such as the collection information table, large-scale data updates will cause problems such as locking the table and blocking online business operations. Therefore, the embodiment of the present application adopts a triggered update method to achieve a full update of the collection data in the collection information table.

[0066] As an example, the collection system receives query request information, where the query request information is used to request a query for one or more collection data, and queries the one or more collection data from an updated collection information table sub-table based on the query request information. Based on the queried one or more collection data, the historical collection data in the collection information table main table is updated, and the one or more collection data in the collection information table sub-table are marked as updated.

[0067] Exemplarily, when the collection system performs a special transaction query operation, the latest collection data is obtained from the collection information table sub-table and returned to the user. At the same time, the latest collection data obtained is updated to the collection information table main table. At the same time, the collection data in the collection information table sub-table is set to an updated status and will not be updated the next time it is queried.

[0068] This solution implements the update of a single household or a small batch of collection data in the collection information table. The update time is short and the possibility of locking the table is avoided. When the collection data is queried from the main table of the collection information table during the execution of ordinary transactions, the collection data obtained is the latest state. In the end, although all the data in the main table of the collection information table is not updated to the latest, the data queried in the main table of the collection information table has been updated to the latest, and a full update has been achieved from the perspective of actual use. If non-latest data is still found when executing ordinary transactions, the data update operation can be triggered by special transaction queries.

[0069] The technical solution provided by the present application is that the collection system extracts the collection data to be updated from the full credit card basic data in the system based on the latest overdue credit card account data obtained, and then updates the collection data to be updated based on the obtained incremental credit card basic data to obtain the latest collection data. It adopts a method of separating the collection data update and the credit card basic data update, avoids the update of the collection data by updating the full credit card basic data, shortens the update time of the collection data, and improves the update efficiency of the collection data.

[0070] Figure 4 This is a flow chart of a method for updating collection data according to an embodiment of the present application. Figure 4As shown, the method at least includes S401 to S409. The method is executed by the collection system, which can be Figure 1 The collection system in 120.

[0071] S401, obtaining incremental credit card basic data and overdue credit card account data.

[0072] S402, extracting the collection data to be updated from the local full credit card basic data based on the overdue credit card account data.

[0073] S403, updating the collection data to be updated according to the acquired incremental credit card basic data to obtain the latest collection data.

[0074] It should be noted that S401 to S403 may refer to S301 to S303 and will not be described in detail here.

[0075] S404, based on the collection information table in the collection system, a collection information table sub-table is established, the collection information table includes historical collection data, and the historical collection data in the collection information table sub-table is consistent with the historical collection data in the collection information table.

[0076] The main collection information table in the collection system includes historical collection data and is used to perform online business for all transactions in the banking system; while the secondary collection information table is only used for querying some special transactions.

[0077] S405, updating the historical collection data in the collection information table sub-table according to the latest collection data to obtain an updated collection information table sub-table.

[0078] For online hot tables such as the collection information table, large-scale data updates may cause problems such as locking the table and blocking the development of online business. Therefore, the latest collection data is first updated to the collection information table sub-table for use in some special transaction queries that are sensitive to the timeliness of basic customer information.

[0079] S406, receiving query request information, where the query request information is used to request a query for one or more collection data.

[0080] S407: query the one or more collection data from the updated collection information table sub-table according to the query request information.

[0081] S408: Update the historical collection data in the collection information table according to the one or more collection data found.

[0082] In one possible implementation, the collection system updates the historical collection data in the main table of the collection information table based on the latest one or more collection data retrieved from the sub-table of the collection information table, thereby realizing the update of a single collection data or a small batch of collection data in the main table of the collection information table, and avoiding the situation where large-scale data updates to hot tables such as the main table of the collection information table cause table locking or affect online business.

[0083] S409: Mark the one or more pieces of collection data found in the collection information table sub-table as being in an updated state.

[0084] In one possible implementation, after the historical collection data in the main table of the collection information table is updated based on one or more collection data queried from the sub-table of the collection information table, the one or more collection data in the sub-table of the collection information table are marked as updated, and the next time the one or more collection data are queried, the main table of the collection information table will no longer be updated.

[0085] The technical method provided by the present application does not require modification of the core system, thus reducing the difficulty of implementation; it adopts a mode in which collection data updates and credit card basic data updates are separated, adjusts the update method, narrows the update scope, and effectively shortens the update time of collection data; it adopts a mode of directional update of the collection information table sub-table, thus solving the problem that batch data updates in the collection information table main table cannot be synchronized with online business; it adopts a triggered update method, thus realizing the full update of active data actually in use in the collection information table.
