With the continuous growth of customer group information data, big data technology is generally used to maintain the customer group information data, such as MongoDB database. The financial business system receives the data request initiated by the salesperson, and then compares the received interface data with the obtained database data. If the comparison result is that the data is the same, the business operation corresponding to the data request is executed, such as modifying the data. For example, the specific comparison method can be to first convert the interface data and MongoDB data corresponding to the data request into a Json string, then convert them into a char array, and finally traverse and compare the char arrays one by one to see if they are the same.

In addition, although the functional modules are divided in the device schematic diagram and the logical order is shown in the flow chart, in some cases, the steps shown or described can be performed in a different order than the module division in the device schematic diagram or the order in the flow chart.

[0024] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used in this specification includes any and all combinations of one or more of the related listed items.

[0025] To facilitate understanding of this embodiment, a database string comparison method disclosed in the embodiment of the present application is first described in detail. Figure 1 , Figure 1 is a schematic diagram of the operating environment of the database string comparison method provided in the embodiment of the present application, such as Figure 1As shown, the execution subject of the database string comparison method provided in the embodiment of the present application is generally an electronic device with certain computing capabilities, such as a computer device. In some possible implementations, the database string comparison method can be implemented by a processor calling a computer-readable instruction stored in a memory. Figure 1 The computer device in the term can be a server. The server can be an independent server or a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, content delivery networks (CDNs), and big data and artificial intelligence platforms. It can be understood that Figure 1 The number of computer devices in the figure is only for reference and can be expanded to any number according to actual needs.

[0026] Please continue reading Figure 2 , Figure 2 is a schematic diagram of the execution flow of the database string comparison method provided in the embodiment of the present application, such as Figure 2 As shown, the following steps are included:

[0027] S1. Parse the received string comparison request to obtain a first string to be compared.

[0028] Among them, the above-mentioned string comparison request is generally initiated by the client through the access interface provided by the server. The client first generates a corresponding string comparison request according to the business needs and the string to be compared, and then sends the generated string comparison request to the server. For example, in the insurance sales system, the salesperson uses the customer's name on the client to inquire whether the customer has purchased a certain insurance product. After receiving the customer's name, the server needs to use the name to compare one by one in the list of people who have purchased the insurance product stored in the database.

[0029] S2. According to the string comparison request, obtain a corresponding second string from the target database.

[0030] The target database may be a non-relational database (NoSQL), such as a document database (such as MongoDB), a key-value database (such as Redis), a column family database (such as Cassandra), a graph database (such as Neo4j), etc. In the traditional comparison method, the interface string data and the database string data (such as the string in MongoDB) are uniformly converted into Json strings, and then converted into char arrays, and finally the char data are traversed one by one to compare whether they are the same. However, when dealing with a scenario with more than one billion string data, performance issues need to be considered. From the above program operation, it can be seen that it is an operation that consumes a lot of CPU resources.

[0031] S3. Convert the first character string into a first numerical value corresponding to a preset data system, and convert the second character string into a second numerical value corresponding to the preset data system.

[0032] Please continue reading Figure 3 , Figure 3 is a schematic diagram of the execution flow of string conversion in the database string comparison method provided in the embodiment of the present application, such as Figure 3 As shown, it may specifically include steps S31 to S36.

[0033] S31. Initialize a first initial value and a second initial value, wherein the first initial value is not equal to the second initial value.

[0034] For example, the first initial value X is set to 1, and the second initial value Y is set to 0;

[0035] S32, sequentially obtain each target character in the first character string, and convert the target character into a target character code value encoded in a preset character set.

[0036] As an optional implementation, the above-mentioned preset character set encoding is ASCII encoding, and the step of converting the target character to the target character encoding value of the preset character set encoding in step S32 can be: converting the target character to the corresponding ASCII encoding value, wherein the ASCII encoding value is decimal.

[0037] For example, taking the character string "CUST123" as an example, after converting to ASCII code values, the values ​​​​can be obtained in sequence: 67, 85, 83, 84, 1, 2, 3 (C corresponds to 67, U corresponds to 85, and so on).

[0038] S33, accumulating the target character code value and the first initial value to obtain a first sum value.

[0039] For example, continuing to accumulate according to the above example of the string “CUST123”, the first sum value can be 326.

[0040] S34, accumulating the target character code value, the second initial value and the second sum value to obtain a second sum value.

[0041] For example, continuing to accumulate according to the above example of the string "CUST123", the second sum value can be 1756.

[0042] S35, converting the first sum value and the second sum value into a third sum value and a fourth sum value of a preset data system respectively.

[0043] As an optional implementation, if the preset data system is hexadecimal, then step S35 may specifically include: converting the first sum value and the second sum value into the third sum value and the fourth sum value in hexadecimal respectively.

[0044] For example, continuing with the example of the above character string "CUST123", the first sum value 326 is converted to the third sum value 0x146, and the second sum value 1756 is converted to 0x06dc.

[0045] S36. Link the third sum and the fourth sum to obtain the first value.

[0046] As an optional implementation, the above step S36 can be specifically as follows: setting the third sum value to the high-order word of the first numerical value, and setting the fourth sum value to the low-order word of the first numerical value; or, setting the third sum value to the low-order word of the first numerical value, and setting the fourth sum value to the high-order word of the first numerical value.

[0047] For example, continuing with the example of the above character string "CUST123", the third sum value is set as the high-order word, and the fourth sum value is set as the low-order word, then the first numerical value 0x06dc016 can be obtained.

[0048] As an optional implementation, the conversion method of the second string is the same as the conversion method of the first string, that is, the second string can be used to replace the first string, and then the steps of setting the first initial value to the third value, the second initial value to the fourth value to linking the third sum value and the fourth sum value are re-executed to obtain the second value.

[0049] As a preferred implementation, please continue to refer to Figure 4 , Figure 4 is a schematic diagram of the execution flow of pre-storing strings in the database string comparison method provided in an embodiment of the present application, such as Figure 4 As shown, the process may include steps S11 to S14.

[0050] S11. Parse the received string storage request to obtain a second string to be stored.

[0051] Among them, similar to the aforementioned string comparison request, the client sends a string storage request to the server. After the server verifies, it stores the corresponding string in the import database. For example, the salesperson of the insurance sales system adds a customer purchase record to the sales system on the client, and the customer's name will be sent to the server of the insurance sales system. After the server performs the corresponding data verification, it will save the customer name to the corresponding deployed database.

[0052] S12, replace the first string with the second string, and perform the steps of initializing the first initial value and the second initial value to linking the third sum value and the fourth sum value, to obtain the second character value corresponding to the second string. That is, using the same string conversion rule as above, it can be ensured that when comparing, the character values ​​corresponding to the same string are the same, and the character values ​​corresponding to different strings are different.

[0053] S13, storing the second character string and the second character value in the target database.

[0054] S14, when receiving a comparison request for the second character string, obtaining a second character value from the target database. When performing character string comparison, only the character string in the comparison request can be converted into a corresponding character value, thereby reducing the step of converting the character string in the database into a character value, further reducing the consumption and occupation of system computing resources during character string comparison, and improving the efficiency of database character string comparison.

[0055] S4. Compare the first value and the second value to see whether they are the same, and set the comparison result as the return result of the string comparison request.

[0056] As another preferred implementation, when the client initiates a string comparison request, the client can first convert the string to be compared into a corresponding character value, and the process of converting the above-mentioned first string into a corresponding first value is processed on the client. Such an operation can further reduce the conversion processing of string data on the server side, and the string value comparison can be directly performed on the server side to obtain the comparison result. In addition to reducing the consumption and occupation of system computing resources, the efficiency of database string comparison is improved, and the security during data transmission can be improved. What is transmitted during the transmission process is the string value rather than the specific string.

[0057] The database string comparison method provided in the embodiment of the present application obtains a first string to be compared by parsing a received string comparison request; obtains a corresponding second string from a target database according to the string comparison request; converts the first string into a first numerical value corresponding to a preset data system, and converts the second string into a second numerical value of the preset data system; compares whether the first numerical value and the second numerical value are the same, and sets the comparison result as the return result of the string comparison request, which not only reduces the consumption and occupation of system computing resources, but also improves the efficiency of database string comparison.
