[0046] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0047] In one embodiment, Figure 1 As shown, a method for storing financial account data based on a distributed storage system is provided, and the distributed storage system includes multiple storage units. This embodiment is illustrated by applying the method to a server in a distributed storage system. It can be understood that the method can also be applied to a system including a terminal and a server, and is implemented through the interaction between the terminal and the server. In this embodiment, the method includes the following steps:

[0048] S101, determining a first financial account and a second financial account whose account data are respectively stored in different storage units of a distributed storage system.

[0049] In a specific implementation, the distributed storage system includes multiple storage units, and the multiple storage units can store account data of different financial accounts. For the sake of distinction, in this application, multiple financial accounts whose account data are stored in different storage units are referred to as first financial accounts and second financial accounts.

[0050] In some optional embodiments, the storage unit may be a database, a database table in a database, or a server.

[0051] In some optional embodiments, after receiving the account relationship maintenance request, the first financial account and the second financial account may be determined according to the account identifier carried in the account relationship maintenance request.

[0052] S102: Acquire an account relationship between the first financial account and the second financial account.

[0053] After the first financial account and the second financial account are determined, a relationship analysis may be performed on the first financial account and the second financial account, and the account relationship between the first financial account and the second financial account may be obtained according to the analysis result.

[0054] S103, storing the account relationship in a storage unit corresponding to the first financial account, and storing the account relationship in a storage unit corresponding to the second financial account, so that when receiving an associated account query request for the first financial account or the second financial account, the account relationship is obtained from the storage unit corresponding to the first financial account or the storage unit corresponding to the second financial account, and the account data of the associated account is obtained according to the account relationship.

[0055] In actual applications, after determining the account relationship between the first financial account and the second financial account, the account relationship can be stored in the corresponding storage units, that is, the account relationship can be stored in the storage unit corresponding to the first financial account, and the account relationship can be stored in the storage unit corresponding to the second financial account. Then, when receiving an associated account query request for the first financial account, the account relationship with the first financial account can be obtained from the storage unit corresponding to the first financial account, and the account data of the associated account of the first financial account can be determined based on the account relationship. Alternatively, when receiving an associated account query request for the second financial account, the account relationship with the second financial account can be obtained from the storage unit corresponding to the second financial account, and the account data of the associated account of the second financial account can be determined based on the account relationship.

[0056] In this embodiment, it is possible to determine the first financial account and the second financial account whose account data are stored in different storage units of the distributed storage system respectively; then, the account relationship between the first financial account and the second financial account can be obtained; thereafter, the account relationship can be stored in the storage unit corresponding to the first financial account, and the account relationship can be stored in the storage unit corresponding to the second financial account, and then, when receiving a query request for an associated account for the first financial account or the second financial account, the account relationship can be obtained from the storage unit corresponding to the first financial account or the storage unit corresponding to the second financial account, and the account data of the associated account can be obtained according to the account relationship. In this application, on the one hand, by storing a large amount of account data in different storage units respectively, the corresponding query range when querying the associated account in the subsequent query can be effectively narrowed, and on the other hand, by identifying the account relationship and storing it in the corresponding storage unit respectively, the account data of the associated account can be quickly obtained according to the account relationship, reducing the number of queries and data search time in the entire system, and effectively improving the query efficiency of the account data of the associated account.

[0057] In addition, the unitized distributed storage of multiple financial accounts and their account relationships through storage units increases the flexibility of account information management and improves the efficiency and rationality of account relationship management.

[0058] In one embodiment, in step S103, storing the account relationship in a storage unit corresponding to the first financial account and storing the account relationship in a storage unit corresponding to the second financial account may include the following steps:

[0059] If the account relationship includes a positive relationship between the first financial account and the second financial account, and a negative relationship between the second financial account and the first financial account, the positive relationship is stored in a storage unit corresponding to the first financial account, and the negative relationship is stored in a storage unit corresponding to the second financial account.

[0060] In a specific implementation, a bidirectional relationship type may exist between the first financial account and the second financial account. The bidirectional relationship type may be understood as the first financial account and the second financial account respectively playing different roles in the account relationship, such as parents, children, spouse, etc. If the user corresponding to the first financial account is the parent of the user corresponding to the second financial account, then the user corresponding to the second financial account is the child of the user corresponding to the first financial account.

[0061] Based on this, in this embodiment, account relationships can be distinguished to determine positive relationships and negative relationships, wherein the positive relationship can be understood as the account relationship understood from the perspective of the first financial account, and the negative relationship can be understood as the account relationship understood from the perspective of the second financial account.

[0062] After obtaining the positive relationship and the negative relationship, the positive relationship can be stored in the storage unit corresponding to the first financial account, and the negative relationship can be stored in the storage unit corresponding to the second financial account. Thus, the account relationship between the financial account and other financial accounts can be accurately recorded in different storage units.

[0063] In one embodiment, Figure 2 As shown, in step S102, obtaining the account relationship between the first financial account and the second financial account may include the following steps:

[0064] S201, receiving a reference account relationship between a first financial account and a second financial account input by a first financial account.

[0065] In a specific implementation, the user may input the account relationship between the first financial account and the second financial account through the first financial account, and the account relationship may be referred to as a reference account relationship.

[0066] S202, determining the relationship type of the reference account relationship.

[0067] After obtaining the reference account relationship, the corresponding relationship type can be determined. In some embodiments, the relationship type can include an equal relationship type and a two-way relationship type, wherein the equal relationship type can include at least one of the following: a friend relationship, a business relationship. Exemplarily, a business relationship can include a guarantor, a stock owner, a beneficiary, etc. The two-way relationship type can include at least one of the following: a parent and a child, a spouse.

[0068] In some optional embodiments, multiple relationships may be classified in advance to determine the classification results, and then, after the reference account is determined, the corresponding relationship type may be determined by matching with the multiple relationships.

[0069] S203: If the relationship type is an equal relationship type, determine the reference account relationship as the account relationship to be stored in the storage unit corresponding to the first financial account and the storage unit corresponding to the second financial account.

[0070] If the relationship type is an equal relationship type, the reference account relationship can be determined as the account relationship to be stored in the storage unit corresponding to the first financial account and the storage unit corresponding to the second financial account. In addition, in some embodiments, the account relationship of the equal relationship type can also be distinguished in positive and negative directions.

[0071] S204: If the relationship type is a bidirectional relationship type, the reference account relationship is determined as a positive relationship, and a negative relationship corresponding to the positive relationship is determined.

[0072] If the relationship type is a bidirectional relationship type, the reference account relationship provided by the first financial account may be determined as a positive relationship, and based on the positive relationship, a negative relationship between the second financial account and the first financial account may be determined.

[0073] For example, as shown in Table 1 below, the account relationship between financial account 1 and financial account 2 and financial account 3 is provided:

[0074] Table 1

[0075]

[0076] When maintaining account relationships, if the storage space (such as storage unit) of financial account 1 is located in the table of unit 1, after financial account 1 registers a relationship information with financial account 2, the relationship type is determined. If it is a social relationship, then according to the mapping relationship, an account relationship information is recorded in the table of unit 2 of the storage space of financial account 2. If financial account 1 is registered as the stock owner of financial account 3, the relationship type is determined. If it is a business relationship, a reverse business relationship is recorded in unit 3 where financial account 3 is located, and the relationship direction is recorded as reverse.

[0077] In this embodiment, by determining the recording method of the account relationship in multiple storage units according to the relationship type when receiving the reference relationship, the accuracy of account relationship maintenance can be effectively improved, and it is convenient to accurately screen out the associated accounts with the specified relationship in the subsequent process.

[0078] In one embodiment, after storing the account relationship in the storage unit corresponding to the first financial account and storing the account relationship in the storage unit corresponding to the second financial account, the method may further include the following steps:

[0079] In response to a modification request for an account relationship, the account relationship stored in a storage unit corresponding to the first financial account and the account relationship stored in a storage unit corresponding to the second financial account are locked; and according to a new account relationship carried in the modification request, the locked account relationship in the storage unit corresponding to the first financial account and the storage unit corresponding to the second financial account are modified.

[0080] In this embodiment, when a modification request for a stored account relationship is received, a locking process may be performed first, that is, the account relationship stored in the storage unit corresponding to the first financial account and the account relationship stored in the storage unit corresponding to the second financial account may be determined and locked. In some optional embodiments, the locking process may be understood as invalidating them, for example, first invalidating the account relationship between the first financial account and the second financial account, and then invalidating the reverse relationship between the first financial account and the second financial account.

[0081] Then, the locked account relationship can be modified according to the new account relationship carried in the modification request, thereby maintaining the correspondence between the account relationship stored in the storage unit corresponding to the first financial account and the storage unit corresponding to the second financial account.

[0082] In some other embodiments, if it is necessary to delete the account relationship stored in the storage unit corresponding to the first financial account and / or the second financial account (i.e., the account relationship between the first financial account and the second financial account), the account relationship between the first financial account and the second financial account may be invalidated first, and then the reverse relationship between the first financial account and the second financial account may also be invalidated.

[0083] In one embodiment, in step S103, storing the account relationship in a storage unit corresponding to the first financial account may include the following steps:

[0084] An account relationship table stored in a storage unit corresponding to the first financial account is obtained; and an account identifier and an account relationship of the first financial account are associated and stored in the account relationship table.

[0085] In practical applications, when the storage unit is a server or a database, each storage unit may maintain an account relationship table corresponding to the storage unit, and the account relationship table may be used to store the account relationship of each financial account in the storage unit. Furthermore, after obtaining the account relationship between the first financial account and the second financial account, the account identifier of the first financial account and the obtained account relationship may be stored in the account relationship table.

[0086] In addition, the storage unit corresponding to the second financial account may also maintain an account relationship table. Accordingly, when storing the account relationship in the storage unit corresponding to the second financial account, the following steps may be included: obtaining the account relationship table stored in the storage unit corresponding to the second financial account; and associating the account identifier and the account relationship of the second financial account and storing them in the account relationship table.

[0087] In this embodiment, the account relationship of each financial account in the storage unit can be uniformly maintained through the account relationship table, which reduces the time of traversing different database tables, effectively narrows the search scope of account relationship, and improves the search efficiency of financial account data.

[0088] In one embodiment, after storing the account relationship in the storage unit corresponding to the first financial account and storing the account relationship in the storage unit corresponding to the second financial account, the following steps may also be included:

[0089] In response to a query request for associated accounts for the first financial account, the account relationship is acquired from an account relationship table in a storage unit corresponding to the first financial account according to the account identifier of the first financial account.

[0090] In some optional embodiments, a query request for associated accounts for the first financial account may be sent to the server. After receiving the request, the account identifier of the first financial account may be obtained. A storage unit for storing account data of the first financial account may be determined based on the account identifier of the first financial account. Then, an account relationship table may be read from the storage unit, and a corresponding account relationship may be searched in the account relationship table based on the account identifier of the first financial account.

[0091] It is understandable that the method for searching the account relationship of the second financial account may be the same as the method for searching the account relationship of the first financial account. That is, a request for querying the associated account for the second financial account may be sent to the server, and after receiving the request, the account identifier of the second financial account may be obtained, and the storage unit for storing the account data of the second financial account may be determined based on the account identifier of the second financial account, and then the account relationship table may be read from the storage unit, and the corresponding account relationship may be searched in the account relationship table based on the account identifier of the second financial account.

[0092] In this embodiment, the corresponding storage unit can be quickly located through the account identifier of the first financial account and the relevant account relationship can be determined in the account relationship table, thereby improving the search efficiency of the associated account.

[0093] It should be understood that, although the various steps in the flowcharts involved in the above-mentioned embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps does not have a strict order restriction, and these steps can be executed in other orders. Moreover, at least a part of the steps in the flowcharts involved in the above-mentioned embodiments can include multiple steps or multiple stages, and these steps or stages are not necessarily executed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily to be carried out in sequence, but can be executed in turn or alternately with other steps or at least a part of the steps or stages in other steps.
