[0089] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than limiting the present application. For those skilled in the art, the present application can be implemented without some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by showing examples of the present application.

[0090] It should be noted that in this document, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "comprising..." does not exclude the existence of additional identical elements in the process, method, article or device comprising the element.

[0091] Before elaborating on the technical solutions provided by the embodiments of the present application, for the convenience of understanding the embodiments of the present application, the problems existing in the related technologies are specifically described in the present application:

[0092] Currently, after each database updates its own data, it will synchronize and interact these updated data with other databases. For example, database A updates its own data to obtain updated data C; database B updates its own data to obtain updated data D. Subsequently, database A sends updated data C to database B, and database B sends updated data D to database A to achieve the synchronization and interaction of updated data between databases.

[0093] However, during the synchronization and interaction of updated data between databases, illegal access may occur, that is, the database is invaded by data, and these invaded data will cause the leakage of updated data synchronized and interacted by the database.

[0094] In the related technology, the method of setting up an interception node is usually adopted to intercept the invaded data, but this method is relatively blind, and users do not know where to set up the interception node. Therefore, the security of the updated data synchronized and interacted by the database is relatively low.

[0095] In addition, during the process of synchronizing and interacting data between databases, there are other problems, such as: there is a time delay during the process of synchronizing and interacting data, resulting in the database being unable to obtain the required data in a timely manner. Also, when multiple databases modify the same data simultaneously, conflicts occur, resulting in inconsistent data and ultimately causing the data to be unavailable or damaged.

[0096] Embodiments of the present application provide a method, apparatus, device, computer storage medium, and computer program product for updating data synchronization detection, which can solve at least one of the above technical problems existing in the related art.

[0097] During the process of synchronizing the data of the first database and the second database in the distributed database through the data interaction chain in the embodiment of the present application, when it is detected that there is intrusion data, the first preset transmission time and the first actual transmission time are obtained. The difference between the first preset transmission time and the first actual transmission time is compared with a preset value to obtain a first comparison result. According to the first comparison result, it is determined that there is intrusion data in the target database. According to the target database, the interception interval corresponding to the target database is obtained. In the target database, an interception node corresponding to the number of the interception intervals is created to intercept the intrusion data. By obtaining the first preset transmission time and the first actual transmission time, the present application can determine which database the intrusion data appears in according to the difference between the above two times, so that an interception node can be set at the accurate position to intercept the intrusion data, thereby improving the security of the updated data in the database synchronization interaction.

[0098] The method for updating data synchronization detection provided by the embodiments of the present application is introduced below.

[0099] Figure 1 The flowchart of the method for updating data synchronization detection provided by an embodiment of the present application is shown. As Figure 1 shown, the method may include steps S110 - S150.

[0100] S110: During the process of synchronizing the data of the first database and the second database in the distributed database through the data interaction chain, when it is detected that there is intrusion data, obtain the first preset transmission time and the first actual transmission time.

[0101] In this embodiment, during the process of synchronizing the data of the first database and the second database in the distributed database by using the data interaction chain, it is detected whether there is intrusion data. When the intrusion data is detected, the first preset transmission time and the first actual transmission time are obtained.

[0102] Among them, the data interaction chain is used for data interaction and transmission between databases.

[0103] Among them, the first preset transmission time represents the preset transmission time for the updated data in the synchronous distributed database to reach the intermediate node, the first actual transmission time represents the actual transmission time for the updated data to reach the intermediate node, and the intermediate node is set at the midpoint position of the data interaction chain.

[0104] In the step process of the embodiment of the present application, when intrusion data is detected, by obtaining the first preset transmission time and the first actual transmission time, it is convenient to subsequently determine the specific location of the intrusion data according to the first preset transmission time and the first actual transmission time.

[0105] S120: Compare the difference between the first preset transmission time and the first actual transmission time with a preset value to obtain a first comparison result.

[0106] In this embodiment, after obtaining the first preset transmission time and the first actual transmission time, calculate the difference between the first preset transmission time and the first actual transmission time, and compare this difference with the preset value to obtain a first comparison result.

[0107] S130: Determine that there is intrusion data in the target database according to the first comparison result.

[0108] In this embodiment, after obtaining the first comparison result, it can be determined that there is intrusion data in the target database according to the first comparison result.

[0109] Among them, the target database includes the first database or the second database.

[0110] S140: According to the target database, obtain the interception interval corresponding to the target database.

[0111] In this embodiment, according to the determined target database, obtain the interception interval corresponding to the target database.

[0112] In one embodiment, the interception interval corresponding to the target database can be calculated according to the parameters corresponding to the target database.

[0113] S150: Create the corresponding number of interception nodes in the target database according to the interception interval to intercept intrusion data.

[0114] In this embodiment, after determining the interception interval corresponding to the target database, create the corresponding number of interception nodes in the target database to intercept intrusion data.

[0115] It should be noted that the intrusion data intrudes inside the database and does not exist at a certain position in the data interaction chain.

[0116] In the process of synchronizing the data of the first database and the second database in the distributed database through the data interaction chain, when intrusion data is detected, the first preset transmission time and the first actual transmission time are obtained. The difference between the first preset transmission time and the first actual transmission time is compared with a preset value to obtain a first comparison result. According to the first comparison result, it is determined that there is intrusion data in the target database. According to the target database, an interception interval corresponding to the target database is obtained. In the target database, an interception node corresponding to the number of the interception intervals is created to intercept the intrusion data. By obtaining the first preset transmission time and the first actual transmission time, the present application can determine which database the intrusion data appears in according to the difference between the above two times, so that an interception node can be set at an accurate position to intercept the intrusion data, thereby improving the security of the updated data in the database synchronization interaction.

[0117] In one embodiment, the first preset transmission time can be calculated according to the preset transmission speed of the updated data in the data interaction chain and the path length of the data interaction chain; the first actual transmission time can be calculated according to the transmission start time and the transmission end time corresponding to the updated data.

[0118] In one embodiment, the expression for calculating the first preset transmission time is shown in formula (1).

[0119]

[0120] where t b represents the first preset transmission time, t 1 represents the transmission start time, and T b represents the second preset transmission time.

[0121] The expression for calculating the second preset transmission time is shown in formula (2).

[0122]

[0123] where T b represents the second preset transmission time, X represents the transmission path length of the data interaction chain, V represents the preset transmission speed, and t 1 represents the transmission start time.

[0124] In one embodiment, the expression for calculating the first actual transmission time is shown in formula (3).

[0125]

[0126] where t s represents the first actual transmission time, t 1 represents the transmission start time, and T s represents the second actual transmission time.

[0127] The expression for calculating the second actual transmission time is shown in Formula (4).

[0128] T s = t 2 - t 1 (4)

[0129] Wherein, T s represents the second actual transmission time, t 2 represents the transmission end time, and t 1 represents the transmission start time.

[0130] In one embodiment, the interception node may include an intrusion database, and the intrusion database is used to compare the consistency of the data characteristics of the intrusion data with the data characteristics in the intrusion database.

[0131] In one embodiment, after intercepting the intrusion data, the interception node may generate an abnormal interception alarm signal for notifying the user to perform corresponding processing.

[0132] In one embodiment, the target database includes a second database; according to the first comparison result, determining that there is intrusion data in the target database may include step S131.

[0133] S131: When the first comparison result indicates that the difference is equal to a preset value, it is determined that there is intrusion data in the second database.

[0134] In this embodiment, if the first comparison result indicates that the difference is equal to the preset value, it is determined that there is intrusion data in the second database.

[0135] In one example, the preset value may be 0.

[0136] In one embodiment, if the first comparison result indicates that the difference is equal to 0, it is determined that there is intrusion data in the second database.

[0137] In one example, the second database may be a database for receiving updated data.

[0138] In the embodiment of the present application, when comparing that the difference is equal to the preset value, it can accurately determine the database with intrusion data, which is convenient for subsequently setting an interception node in the database to improve the security of the updated data in the database synchronization interaction.

[0139] In one embodiment, the method for updating data synchronization detection further includes steps S132 - S133, as Figure 2 shown.

[0140] S132: When the difference indicated by the first comparison result is not equal to the preset value, compare the difference with the target difference to obtain a second comparison result.

[0141] Wherein, the target difference represents the difference between the second preset transmission time and the second actual transmission time. The second preset transmission time represents the preset transmission time for the updated data to pass through the data interaction chain throughout the process, and the second actual transmission speed represents the actual transmission time for the updated data to pass through the data interaction chain throughout the process.

[0142] In this embodiment, if the difference indicated by the first comparison result is not equal to the preset value, the difference can be compared with the target difference to obtain a second comparison result.

[0143] S133: Determine that there is intrusion data in the target database according to the second comparison result.

[0144] In this embodiment, after obtaining the second comparison result, it can be determined that there is intrusion data in the target database according to the second comparison result.

[0145] In the embodiment of the present application, when the difference is not equal to the preset value, by comparing the comparison difference with the target difference, it is further determined according to the comparison result which database has intrusion data, facilitating subsequent setting of an interception node in this database to improve the security of the updated data in the database synchronization interaction.

[0146] In one embodiment, the target database includes a first database and a second database; determining that there is intrusion data in the target database according to the second comparison result may include step S1331 and step S1332, as Figure 3 shown.

[0147] S1331: When the absolute value of the difference indicated by the second comparison result is equal to the target difference, determine that there is intrusion data in the first database.

[0148] In this embodiment, if the absolute value of the difference indicated by the second comparison result is equal to the target difference, it can be determined that there is intrusion data in the first database.

[0149] In one example, the first database may be the database that sends the updated data.

[0150] S1332: When the absolute value of the difference indicated by the second comparison result is less than the target difference, determine that there is intrusion data in the second database.

[0151] In this embodiment, if the absolute value of the difference indicated by the second comparison result is less than the target difference, it can be determined that there is intrusion data in the second database.

[0152] In one example, the second database may be the database that receives the updated data.

[0153] In the embodiment of the present application, by comparing the absolute value of the difference with the target difference, it is possible to further determine the database where the intrusion data exists.

[0154] In one embodiment, according to the target database, obtaining the interception interval corresponding to the target database may include steps S141 - S143, as Figure 4 shown.

[0155] S141: Obtain the second preset transmission time and the second actual transmission time.

[0156] Among them, the second preset transmission time represents the preset transmission time for the update data to pass through the data interaction chain in its entirety, and the second actual transmission speed represents the actual transmission time for the update data to pass through the data interaction chain in its entirety.

[0157] In this embodiment, the second preset transmission time and the second actual transmission time can be obtained.

[0158] In one embodiment, the second preset transmission time can be calculated based on the preset transmission speed of the update data in the data interaction chain and the path length of the data interaction chain; the second actual transmission time can be calculated based on the transmission start time and the transmission end time corresponding to the update data.

[0159] S142: Calculate the difference between the second preset transmission time and the second actual transmission time to obtain the target difference.

[0160] In this embodiment, when the second preset transmission time and the second actual transmission time are obtained, the difference between the second preset transmission time and the second actual transmission time can be calculated to obtain the target difference.

[0161] S143: Determine the interception interval according to the weight coefficient, difference, and target difference corresponding to the target database.

[0162] In this embodiment, when the target difference is calculated, the interception interval corresponding to the target database can be determined according to the weight coefficient, difference, and target difference corresponding to the target database.

[0163] In one embodiment, arithmetic operations can be performed on the weight coefficient, difference, and target difference corresponding to the target database to obtain the interception interval corresponding to the target database.

[0164] In one example, if the target database is the first database, the weight coefficient corresponding to the first database is L1; if the target database is the second database, the weight coefficient corresponding to the second database is L2.

[0165] In the embodiments of the present disclosure, by obtaining the second preset transmission time and the second actual transmission time, the target difference can be determined, so that the interception interval corresponding to the target database can be accurately determined.

[0166] In one embodiment, the weight coefficients include a first weight coefficient, a second weight coefficient, a third weight coefficient, and a fourth weight coefficient. Determining the interception interval according to the weight coefficient, difference, and target difference corresponding to the target database may include steps S1431 - S14310, as Figure 5 shown.

[0167] S1431: When the target database represents the first database, determine the first weight coefficient and the second weight coefficient.

[0168] In this embodiment, if the target database represents the first database, the first weight coefficient and the second weight coefficient corresponding to the first database can be obtained.

[0170] In this embodiment, the difference between the target difference of each data interaction chain and the absolute value of the difference can be calculated and then added to obtain the first data.

[0171] It can be understood that the first database and the second database can transmit and update data through multiple data interaction chains.

[0172] S1433: Multiply the first data by the first weight coefficient to obtain the second data.

[0173] In this embodiment, after obtaining the first data, the first data can be multiplied by the first weight coefficient to obtain the second data.

[0174] S1434: Add the second data and the product of the difference and the second weight coefficient to obtain the third data.

[0176] S1435: Determine the value obtained by dividing the preset target value by the third data as the interception interval corresponding to the first database.

[0177] In this embodiment, after obtaining the third data, the value obtained by dividing the preset target value by the third data can be determined as the interception interval corresponding to the first database.

[0178] In one example, the target value can be 1.

[0179] S1436: When the target database represents the second database, determine the third weight coefficient and the fourth weight coefficient.

[0180] In this embodiment, if the target database represents the second database, the third weight coefficient and the fourth weight coefficient corresponding to the second database can be obtained.

[0181] S1437: Add the absolute values of the differences of each data interaction chain to obtain the fourth data.

[0182] In this embodiment, the absolute values of the differences of each data interaction chain can be added to obtain the fourth data.

[0183] S1438: Multiply the fourth data by the third weight coefficient to obtain the fifth data.

[0184] In this embodiment, after obtaining the fourth data, the fourth data can be multiplied by the third weight coefficient to obtain the fifth data.

[0185] S1439: Add the fifth data and the product of the target difference and the fourth weight coefficient to obtain the sixth data.

[0186] In this embodiment, after obtaining the fifth data, the product of the target difference and the fourth weight coefficient can be calculated, and then this product is added to the fifth data to obtain the sixth data.

[0187] S14310: Determine the interception interval corresponding to the second database as the value obtained by dividing the target value by the sixth data.

[0188] In this embodiment, after obtaining the sixth data, the value obtained by dividing the target value by the sixth data can be determined as the interception interval corresponding to the second database.

[0189] In one example, the expression for determining the interception interval corresponding to the first database is shown in formula (5).

[0190]

[0191] where T q represents the interception interval of the first database, n represents the number of data interaction chains, T 1 represents the difference, T 2 represents the target difference, w 1 represents the first weight coefficient, w 2 represents the second weight coefficient.

[0192] In another example, the expression for determining the interception interval corresponding to the second database is shown in formula (6).

[0193]

[0194] Among them, T g represents the interception interval of the second database, n represents the number of data interaction chains, and T 1 represents the difference, and T 2 represents the target difference, and w 3 represents the third weight coefficient, and w 4 represents the fourth weight coefficient.

[0195] According to the weight coefficient, difference, and target difference corresponding to the target database in the embodiments of the present application, the interception interval corresponding to the target database can be accurately determined.

[0196] In one embodiment, during the process of synchronizing the data of the first database and the second database in the distributed database through the data interaction chain, when it is detected that there is intrusion data, before obtaining the first preset transmission time and the first actual transmission time, the method for updating data synchronization further includes steps S210-S250, as Figure 6 shown.

[0197] S210: In response to receiving the first information, transmit the updated data through the data interaction chain based on the first information.

[0198] Among them, the first information includes the preset transmission speed and the transmission start time. The first information represents the updated data synchronization interaction trigger information. The transmission start time represents the time when the updated data starts to be sent from the database, and the preset transmission speed represents the transmission speed of the updated data preset in the data interaction chain.

[0199] In this embodiment, when the first information is received, the updated data can be transmitted through the data interaction chain according to the first information.

[0200] S220: Obtain the transmission end time corresponding to the updated data.

[0201] In this embodiment, the transmission end time corresponding to the updated data can be obtained.

[0202] Among them, the transmission end time refers to the time when the updated data reaches the database that receives the data.

[0203] S230: Obtain the transmission path length of the data interaction chain.

[0204] In this embodiment, the length of the transmission path of the data interaction chain can be obtained.

[0205] S240: Determine the actual transmission speed according to the ratio of the transmission path length to the difference between the transmission end time and the transmission start time.

[0206] In this embodiment, after obtaining the transmission path length, the difference between the transmission end time and the transmission start time can be calculated, and then the transmission path length is divided by this difference to obtain the actual transmission speed.

[0207] In one example, the expression for calculating the actual transmission speed is shown in formula (7).

[0208]

[0209] Wherein, V S represents the actual transmission speed, X represents the transmission path length of the data interaction chain, t 1 represents the transmission start time, and t 2 represents the transmission end time.

[0210] S250: When the difference between the actual transmission speed and the preset transmission speed is less than or equal to the preset speed threshold, it is determined that there is intrusion data.

[0211] In this embodiment, after calculating the actual transmission speed, the difference between the actual transmission speed and the preset transmission speed is calculated. If this difference is less than or equal to the preset speed threshold, it is determined that there is intrusion data.

[0212] Wherein, the magnitude of the preset speed threshold is not fixed and can be set according to user requirements.

[0213] In one example, the expression for calculating the difference between the actual transmission speed and the preset transmission speed is shown in formula (8).

[0214] V c =|V s -V| (8)

[0215] Wherein, V c represents the difference between the actual transmission speed and the preset transmission speed, V s represents the actual transmission speed, and V represents the preset transmission speed.

[0216] The embodiments of the present application compare the difference between the actual transmission speed of the updated data and the preset transmission speed with the preset speed threshold, which can accurately determine whether there is intrusion data in the database, facilitate subsequent execution of corresponding processing operations, and thus improve the security of the updated data for synchronous interaction.

[0217] In one embodiment, before transmitting the updated data through the data interaction chain based on the first information in response to receiving the first information, the method for updating data synchronization detection further includes steps S310 - S350, as Figure 7 shown.

[0218] S310: When it is detected that the third database does not include data corresponding to the received second information, obtain updated data from the fourth database.

[0219] Among them, the second information represents the expected demand information, that is, the problems that the user needs the database to process. The expected demand information is used to update the database, and the data includes updated data.

[0220] In this embodiment, it is detected whether the third database includes data corresponding to the second information according to the received second information. When it is detected that the third database does not include data corresponding to the received second information, obtain updated data from the fourth database.

[0221] In one embodiment, a Structured Query Language (SQL) query method can be used to determine whether the third database includes data corresponding to the second information.

[0222] S320: Use the third database to receive the updated data to obtain the first database.

[0223] In this embodiment, after obtaining the updated data, the third database can be used to receive the updated data to obtain the first database.

[0224] The step process of the embodiment of the present application uses the third database to receive the updated data to obtain the first database, which is equivalent to updating the data in the third database. It can be understood that the prerequisite for the database to perform updated data synchronization and interaction is that the database has been updated. Therefore, by updating the third database to obtain the first database, the subsequent first database and the second database can perform updated data synchronization and interaction.

[0225] S330: Classify the source data in the fourth database according to data characteristics to obtain classified source data.

[0226] Among them, the source data of the fourth database represents part of the data in the fourth database. The acquisition methods of the source data include but are not limited to methods such as sensor data collection, questionnaires, transaction records, web crawlers, and log files.

[0227] In this embodiment, the source data in the fourth database can be classified according to data characteristics to obtain classified source data.

[0228] In one embodiment, the source data in the fourth database can also be classified according to data characteristics to obtain initial classified source data, and then the data structure of the initial classified source data is converted according to a preset data structure to obtain classified source data. In this embodiment, by converting the data structure of the initial classified source data, it is used to keep the source data and the structure data consistent, and it is determined to reduce the occurrence of errors during the data comparison process.

[0229] S340: In the case where it is detected that the classified source data is inconsistent with the corresponding structure data in the fourth database, the classified source data and the structure data are merged to obtain a second database.

[0230] In this embodiment, after obtaining the classified source data, the consistency between the classified source data and the structure data in the fourth database is detected. In the case where it is detected that the classified source data is inconsistent with the corresponding structure data in the fourth database, the classified source data and the structure data are merged to obtain a second database.

[0231] In one embodiment, in the case where it is detected that the classified source data is inconsistent with the corresponding structure data in the fourth database, the classified source data and the structure data can be merged to generate an updated feature database, the source data is classified to generate multiple updated feature databases, and then each updated feature database is merged to obtain a second database.

[0232] In one embodiment, in the case where it is detected that the classified source data is consistent with the corresponding structure data in the fourth database, the classified source data is deleted.

[0233] The step process of the embodiment of the present application obtains a second database by merging the classified source data and the structure data, which is equivalent to updating the fourth database to obtain the second database.

[0234] S350: Connect the first database and the second database to obtain a synchronous distributed database.

[0235] In this embodiment, after obtaining the first database and the second database, the first database and the second database can be combined to obtain a synchronous distributed database.

[0236] In one embodiment, the first database and the second database can be generated into corresponding first nodes and second nodes, and the first node and the second node are sequentially connected through a data interaction chain to obtain a synchronous distributed database.

[0237] The embodiment of the present application can obtain the first database and the second database by receiving or merging the data in the third database and the fourth database, thereby obtaining a synchronous distributed database, which is convenient for subsequent update data synchronization interaction based on the synchronous distributed database.

[0238] In one embodiment, before obtaining updated data from the fourth database when it is detected that the third database does not include updated data corresponding to the received second information, the method for detecting updated data synchronization further includes S410 - S450, as Figure 8 shown.

[0239] S410: Receive third information.

[0240] Among them, the third information includes target data characteristics, the third information represents user demand information, and the target data characteristics include data such as numerical data, text - numerical data, full - text data, term data, image data, and audio - video data.

[0241] In this embodiment, the third information can be received.

[0242] S420: Obtain the target data structure and the target data quantity corresponding to the target data characteristics.

[0243] In this embodiment, the target data structure and the target data quantity can be determined according to the target data characteristics.

[0244] S430: Obtain the target feature database corresponding to the target data characteristics from the fourth database.

[0245] In this embodiment, after determining the target data structure and the target data quantity, the target feature database corresponding to the target data characteristics can be obtained from the fourth database.

[0246] Among them, the target data feature library includes feature databases such as numerical databases, text - numerical databases, full - text databases, term databases, image databases, and audio - video databases.

[0247] S440: Obtain the target data corresponding to the target data structure and the target data quantity from the target feature database.

[0248] In this embodiment, after obtaining the target feature database, the target data corresponding to the target data structure and the target data quantity can be obtained from the target feature database.

[0249] Among them, the target data structure can be one or more.

[0250] S450: Generate the third database based on the target data.

[0251] In this embodiment, after obtaining the target data, the third database can be generated according to the target data.

[0252] It can be understood that, in the embodiments of the present application, by receiving the third information and generating the third database according to the target data of the fourth database, the size of the third database is made smaller than the size of the fourth database. Therefore, the first database generated subsequently based on the third database is smaller and the second database generated based on the fourth database is larger. Since the embodiments of the present application perform update data synchronization interaction between a larger database and a smaller database, avoiding update data synchronization interaction between two larger databases, the latency of the update data synchronization interaction is reduced and the efficiency of the update data synchronization interaction is improved.

[0253] In one embodiment, the method for update data synchronization detection may further include steps S510 - S540, as Figure 9 shown.

[0254] S510: When the difference between the actual transmission speed and the preset transmission speed is greater than the preset speed threshold, obtain the update data by using the fifth database.

[0255] Wherein, the fifth database represents the database for obtaining the update data, and the fifth database includes the first database or the second database.

[0256] In this embodiment, if it is detected that the difference between the actual transmission speed and the preset transmission speed is greater than the preset speed threshold, the update data can be obtained by using the fifth database.

[0257] S520: Based on the fifth database, the characteristic data and data structure corresponding to the update data, map the update data to obtain the target transmission update data.

[0258] In this embodiment, after the fifth database obtains the update data, the update data can be mapped to obtain the target transmission update data according to the fifth database, the characteristic data and data structure corresponding to the update data.

[0259] In one embodiment, after the fifth database obtains the update data, the update data can be mapped into the characteristic database corresponding to the data structure according to the characteristic data and data structure corresponding to the update data to obtain the target transmission update data.

[0260] S530: Detect the consistency between the data characteristics and data structure corresponding to the target transmission update data and the data characteristic library and data structure corresponding to the update data, and detect the consistency between the value of the target transmission update data and the value of the update data.

[0261] In this embodiment, after obtaining the target transmission update data, the consistency between the data characteristics and data structure corresponding to the target transmission update data and the data characteristic library and data structure corresponding to the update data can be detected, and the consistency between the value of the target transmission update data and the value of the update data can be detected.

[0262] S540: When it is detected that the data features and data structure corresponding to the target transmission update data are consistent with the data feature library and data structure corresponding to the update data, and the value of the target transmission update data is consistent with the value of the update data, it is determined that the fifth database is successfully updated.

[0263] In this embodiment, if it is detected that the data features and data structure corresponding to the target transmission update data are consistent with the data feature library and data structure corresponding to the update data, and the value of the target transmission update data is consistent with the value of the update data, it can be determined that the fifth database is successfully updated.

[0264] In the embodiment of the present application, when the database receives the update data, the update data is detected based on the data features and data structure, which can improve the consistency of the update data synchronization interaction and reduce the probability of data unavailability or data corruption.

[0265] In one embodiment, the method for update data synchronization detection may further include step S550 and step S560, as Figure 10 shown.

[0266] S550: When it is detected that the data features and data structure corresponding to the target transmission update data are inconsistent with the data feature library and data structure corresponding to the update data, or the value of the target transmission update data is inconsistent with the value of the update data, obtain the permission list from the preset permission list database.

[0267] Among them, the preset permission list database represents the database for managing the permission list, and the permission list is used to manage the permission accounts for users to access the database.

[0268] In this embodiment, if it is detected that the data features and data structure corresponding to the target transmission update data are inconsistent with the data feature library and data structure corresponding to the update data, or it is detected that the value of the target transmission update data is inconsistent with the value of the update data, the permission list can be obtained from the preset permission list database.

[0269] S560: Modify the permission code corresponding to the permission list so that the data features and data structure corresponding to the target transmission update data are consistent with the data feature library and data structure corresponding to the update data, and the value of the target transmission update data is consistent with the value of the update data.

[0270] In this embodiment, after obtaining the permission list, the permission code corresponding to the permission list can be modified so that the data features and data structure corresponding to the target transmission update data are consistent with the data feature library and data structure corresponding to the update data, and the value of the target transmission update data is consistent with the value of the update data.

[0271] By modifying the permission list in the embodiments of the present application, the consistency between the target transmission of updated data and the updated data can be improved, thereby reducing the probability of data unavailability or data corruption.

[0272] In one embodiment, modifying the permission code corresponding to the permission list may include steps S561 - S563, as Figure 11 shown.

[0273] S561: Modify the permission code corresponding to the permission list and detect whether there is an access by an abnormal permission account.

[0274] In this embodiment, the permission code corresponding to the permission list can be modified, and it is detected whether there is an access by an abnormal permission account.

[0275] S562: Based on the abnormal permission account, generate an abnormal permission list in the case of detecting an access by an abnormal permission account.

[0276] In this embodiment, if it is detected that there is an access by an abnormal account, an abnormal permission list can be generated according to the abnormal permission account.

[0277] S563: Generate an alarm message according to the abnormal permission list.

[0278] In this embodiment, after generating the abnormal permission list, an alarm message can be generated according to the abnormal permission list to notify the user to perform corresponding processing.

[0279] In one embodiment, the user can perform an inhibition process on the abnormal permission list based on the alarm signal to prevent accessing the database.

[0280] By modifying the permission code corresponding to the permission list in the embodiments of the present application, generating an abnormal permission list and giving an alarm, the security of the database can be improved.
