In order to make the technical solutions of the present application better understood, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Based on the above problems, embodiments of the present invention provide a data updating method, which is described in detail below.

A data updating method in the embodiment of the present application is described below with reference to fig. 1, where fig. 1 is a schematic flow chart of the data updating method provided in the embodiment of the present application, and the method specifically includes the following steps S101 to S104.

S101, acquiring a data updating request of the target account.

And the data updating request carries the target account identification of the target account.

The data update request may be a value increase request and a value decrease request, the value increase request is a request for sending money to the target account, and the value decrease request is a request for sending money from the target account to another account. The account identifier refers to a unique identifier of an account, one account corresponds to one unique identifier, different accounts correspond to different unique identifiers, and the unique identifier can be an account number.

As can be seen, in this example, the account identifier is carried in the data update request in advance, so that the account of the data update request is determined based on the account identifier.

And S102, judging whether the target account is a hot spot account or not according to the target account identifier and the target database.

The target database is used for recording a hotspot account and first data of the hotspot account, the first data is used for reflecting second data of the hotspot account, the first data is n times of the second data of the hotspot account, n is greater than 0, specifically, n may be 0.5, 1, 5, and the like, without specific limitation, and the target database includes an account identifier of the hotspot account.

The target database is created by a service provider, stored in electronic equipment provided by the service provider, and used for maintaining a hotspot account and first data of the hotspot account. If the account created by the user is the hotspot account, the server records the account identification of the hotspot account and the first data in the target database. If the account created by the user is not the hotspot account, the server does not record the account identifier of the hotspot account and the first data in the target database.

Specifically, the implementation manner of determining whether the target account is a hotspot account according to the target account identifier and the target database may be: comparing the target account identification with the account identification in the target database one by one; if the target account identification exists in the target database, determining that the target account is the hotspot account; if the target account identification does not exist in the target database, determining that the target account is not the hotspot account.

As can be seen, in this example, only the account identifier of the hot account is stored in the target database in advance, the target account identifier is compared with the account identifiers stored in the target database one by one, if the target database has the target account identifier, it is determined that the target account is the hot account, and if the target database has the target account identifier, it is determined that the target account is not the hot account, so that the intelligence of determining the hot account is improved, and the efficiency of updating the account data is further improved.

The target database may be in the form of a table, or may be in the form of an account set, and is not particularly limited.

Taking three created accounts as an example, if the three created accounts include account a, the account a corresponds to account number 1, and the first data is 200; account B, corresponding to account number 2, with first data of 5000; account C, corresponding to account number 3, and the first data is 9000.

Illustratively, the target database is in the form of a table, and specifically, the aforementioned three accounts created may be recorded as:

account	Account number	First data (element)
			A	1	200.00
B	2	5000.00
			C	3	9000.00

For example, the target database is in the form of an account set, and then the target database may be presented in the following { x, y, z }, where x refers to an account, y refers to an account number, z refers to first data, and the unit is an element, specifically, the aforementioned three created accounts may be recorded as: { account a, account 1, 200.00}, { account B, account 2, 5000.00}, and { account C, account 3, 9000.00 }.

It will be appreciated that the value of the second data may be equal to the value of the first data.

In this example, by maintaining the target database recording the account identifier of the hot account, it can be determined whether the account corresponding to the data update request carrying the target account identifier is the hot account, and the target database is managed in a unified manner.

S103, if the target account is the hotspot account, updating the first data of the target account in the target database according to the data updating request.

And the numerical value of the first data after updating is greater than or equal to 0 and is not equal to the numerical value of the first data before updating.

In a specific implementation, when the data update request is a value increase request, the updated value of the first data is the value of the first data before update and the value of the amount of money of the data update request

And (4) summing. When the data update request is that the numerical value of the first data after update is the numerical value of the first data before update and the numerical value of the amount of money of the data update request

The difference, and only if the value of the first data before update is greater than or equal to the value of the amount of money requested for data update

The first data can be updated successfully.

And S104, updating second data of the target account according to the first data.

In a specific implementation, when the data update request is a value increase request, the updated value of the second data is the value of the second data before update and the value of the amount of money of the data update request

And (4) summing. When the data update request is a value decrease request, the updated value of the second data is the value of the second data before update and the value of the amount of money requested by the data update

Specifically, the second data of the target account can be updated according to the data update request only after the first data of the target account is successfully updated according to the data update request.

It can be seen that, in the embodiment of the application, first, a data update request of a target account is obtained, where the data update request carries a target account identifier of the target account, then, according to the target account identifier and a target database, it is determined whether the target account is a hotspot account, the target database is used to record a hotspot account and first data of the hotspot account, where the first data is used to reflect second data of the hotspot account, and the target database includes an account identifier of the hotspot account, if the target account is a hotspot account, according to the data update request, the first data of the target account in the target database is updated, where a numerical value of the updated first data is greater than or equal to 0 and not equal to a numerical value of the first data before updating, and finally, a numerical value of the second data of the hotspot account is updated according to the first data. It can be seen that, according to the application, the hotspot account and the first data of the hotspot account are maintained in a special database, after the hotspot account data updating request is determined to be obtained, the first data of the hotspot account are updated, the data updating request is recorded, and when the data updating request is processed based on the special database without locking, whether the data updating request can be processed based on the first data can be rapidly identified, and under the condition that the first data is updated successfully, the data updating request is recorded, so that when a plurality of data updating requests without updating the second data exist, the second data cannot be updated concurrently, the error rate of updating the second data is reduced, and the safety of the account is improved.

As a possible implementation manner, the updating the first data of the target account in the target database according to the data update request includes: acquiring a request serial number, a source system, a request type and a service identifier of the data updating request; generating a target index of the data updating request according to the request serial number, the source system, the request type and the service identifier; judging whether the target index is an index appearing for the first time; and if the target index is the index appearing for the first time, updating the first data of the target account in the target database according to the data updating request.

Wherein the source system is a system generating the data update request.

Specifically, the implementation manner of generating the target index of the data update request according to the request serial number, the source system, the request type, and the service identifier may be: generating a first sub-code corresponding to the request serial number according to the request serial number and a first mapping relation, wherein the first mapping relation comprises the corresponding relation between the request serial number and the first sub-code; generating a second subcode corresponding to the source system according to the source system and a second mapping relation, wherein the second mapping relation comprises the corresponding relation between the source system and the second subcode; generating a third subcode corresponding to the request type according to the request type and a third mapping relation, wherein the third mapping relation comprises the corresponding relation between the request type and the third subcode; generating a fourth sub-code corresponding to the service identifier according to the service identifier and a fourth mapping relation, wherein the third mapping relation comprises a corresponding relation between the service identifier and the fourth sub-code; generating the target index according to the first subcode, the second subcode, the third subcode, and the fourth subcode.

Wherein, one request serial number corresponds to one first subcode, and different request serial numbers correspond to different first subcodes; one source system corresponds to one second subcode, and different source systems correspond to different second subcodes; one request type generates a third subcode, and different request types generate different third subcodes; one service identifier generates a fourth subcode, and different service identifiers generate different fourth subcodes.

Further, the implementation manner of generating the target index according to the first sub-code, the second sub-code, the third sub-code, and the fourth sub-code may be: and sequencing the first subcode, the second subcode, the third subcode and the fourth subcode according to a preset arrangement sequence to generate the target index. The preset arrangement sequence may be, from front to back, the first subcode, the second subcode, the third subcode, and the fourth subcode in sequence; the preset arrangement sequence may be the fourth subcode, the third subcode, the second subcode, and the first subcode from front to back, and the preset arrangement sequence is not specifically limited.

As a possible implementation manner, the obtaining of the request serial number, the source system, the request type, and the service identifier of the data update request includes: and acquiring the request serial number, the source system, the request type and the service identifier carried by the data updating request.

It can be seen that in this example, the first data of the target account in the target database is updated based on the data update request only if the target index is the first-appearing index. That is, the first data of the target account in the target database is updated based on the data update request when the data update request is not a repeated data update request.

As a possible implementation, the method further includes: if the target index is not the index appearing for the first time, ending the current process; and generating first information according to the data updating request, and sending the first information to user equipment of a target user, wherein the first information is used for indicating that the target index is abnormal.

The target user can be at least one of a requesting user, a user corresponding to the target account and a data update request supervisor set by a service provider. The target user may also be another user, and is not particularly limited.

The first information includes, but is not limited to, at least one of a request number, a request serial number, a source system, a request type, a service identifier, index duplication information, and request duplication information of the data update request. In a specific implementation, one data update request corresponds to one request number, and different data update requests correspond to different request numbers, the index repetition information may be that the target index is a repetition index, and the request repetition information may be that the data update request is a repetition data update request.

For example, the first information may be "the index of the currently processed data update request is a duplicate index, and the currently processed data update request is a duplicate index," which is not particularly limited.

As can be seen, in this example, when the target index is not the index appearing for the first time, the first data of the target account in the target database is not updated based on the data update request, and the prompt information indicating that the index of the data update request is abnormal is output, so that the first data of the target account is prevented from being affected by the data update request submitted repeatedly, and further, the second data of the target account is prevented from being affected by the data update request submitted repeatedly.

As a possible implementation manner, the updating the first data of the target account in the target database according to the data update request includes: obtaining a numerical value of the first data before updating of the target account; judging whether the data updating request is a numerical value reduction request or not; if the request type is a value reduction request, judging whether the value of the first data before updating is larger than or equal to the value corresponding to the data updating request

A difference of (d); if the request type is a value increasing request, obtaining the updated value of the first data according to the value of the first data before updating and the value corresponding to the data updating request, wherein the updated value of the first data is equal to the value of the first data before updating and the value corresponding to the data updating requestIs/are as follows

The sum of (a) and (b).

For example, when n is 1, that is, when the value of the first data is equal to the value of the second data, if the value of the first data before the update of the target account is 500, the data update request is a value decrease request, and the value of the amount of money of the value decrease request is 201, it is determined that the value 500 of the first data before the update is greater than the value 201 of the amount of money of the value decrease request, and then the value 500 of the first data is updated to 299. If the value of the first data before the update of the target account is 500, the data update request is a value increase request, and the value of the amount of the value increase request is 201, then the value of the first data is updated to be 799.

For example, when n is 2, if the value of the first data before updating of the target account is 500, the data updating request is a value decreasing request, and the value of the amount of money of the value decreasing request is 201, it is determined that the value of the first data before updating 500 is greater than the value of the amount of money of the value decreasing request

I.e., 100.5, the value 500 of the first data is updated to 399.5. If the value of the first data before the update of the target account is 500, the data update request is a value increase request, and the value of the amount of the value increase request is 201, the value 500 of the first data is updated to 600.5.

For example, when n is

If the value of the first data before updating of the target account is 500, the data updating request is a value reduction request, and the value of the amount of money of the value reduction request is 201, then it is determined that the value of the first data before updating 500 is greater than the value of the amount of money of the value reduction request

I.e., 402, the value 500 of the first data is updated to 98. If the value of the first data before the update of the target account is 500, the data update request is a value increase request, and the value of the amount of the value increase request is 201, then the value 500 of the first data is updated to 902.

It can be seen that in this example, when the data update request is a value increase request, the value of the first data can be directly updated to be the sum of the value of the first data before update and the value corresponding to the data update request, and when the data update request is a value decrease request, it is required to determine that the value of the first data before update is greater than or equal to the value corresponding to the data update request, and update the value of the first data to be the sum of the value of the first data before update and the value corresponding to the data update request, so that in a case that updating the first data is successful, the data update request is recorded, so as to ensure that when there are multiple data update requests without updating the second data, the second data cannot be updated concurrently, reduce an error rate of data update, and improve security of the account.

As a possible implementation manner, the determining whether the value of the first data before updating is greater than or equal to the value corresponding to the data updating request is performed

Thereafter, the method further comprises: if the value of the first data before updating is smaller than the value corresponding to the data updating request

Ending the current process; and generating second information according to the data updating request, and sending the second information to user equipment of a target user, wherein the second information is used for indicating that the processing of the data updating request fails.

Wherein the second information includes, but is not limited to, at least one of a request number, a request serial number, a source system, a request type, a service identifier, and processing failure information of the data update request. The processing failure information includes a result of the processing failure of the data update request and a reason.

For example, the second information may be "currently processed data update request processing fails, failure reason: the account balance of the target account is insufficient ", and the second information is not particularly limited.

As can be seen, in this example, when the data update request is a value reduction request, it is necessary to determine that the value of the first data before update is smaller than the value corresponding to the data update request

And ending the current process, outputting prompt information indicating that the data updating request fails to be processed, and avoiding updating the second data of the target account when the numerical value of the second data is smaller than the numerical value corresponding to the data updating request.

As a possible implementation manner, the updating the second data of the target account according to the first data includes: under the condition that the value of the first data changes, adding the data updating request to a request queue, wherein the request queue is used for indicating data updating requests of second data which are not updated and are sequentially arranged in the order from front to back according to the processing time; and updating the numerical value of the second data of the target account according to the data updating requests in the request queue in sequence.

Wherein the change in the value of the first data includes an increase in the value of the first data and a decrease in the value of the first data.

Wherein, according to the data update requests in the request queue in turn, the updating of the value of the second data of the target account may be implemented by performing the following operations for each data update request in the request queue: obtaining a numerical value of the second data of the target account before updating; and obtaining a value of the updated second data according to the value of the second data before updating and a value corresponding to a target data updating request in the currently processed request queue, wherein when the target data updating request in the currently processed request queue is a value decreasing request, the updated value of the second data is equal to a difference between the value of the second data before updating and the value corresponding to the target data updating request, and when the target data updating request in the currently processed request queue is a value increasing request, the updated value of the second data is equal to a sum of the value of the second data before updating and the value corresponding to the target data updating request.

Illustratively, the value of the second data before the update of the target account is 500, the value corresponding to the target data update request is 201, when the target data update request is a value decrease request, the value 500 for updating the second data is 299, and when the target data update request is a value increase request, the value 500 for updating the second data is 701.

It should be noted that, after updating the second data based on the data update request in the request queue, the data update request that has completed the second data update is immediately moved out of the request queue, thereby ensuring that the data update request in the request queue is a data update request that does not update the second data.

It will be appreciated that qualified data update requests (not duplicative and not numeric for the requested amount) are filtered out by the first data of the hotspot account

The data update request is larger than the first data before update), and then the second data of the hotspot account is updated based on the qualified delivery request.
