Description

Technical Field

[0001] This application relates to the technical field of data processing, and in particular, to a method and apparatus for processing virtual asset data and a computer-readable storage medium. Background Art

[0002] In a data processing system, there may be multiple data processing devices. The data in these multiple data processing devices may be isolated from each other, and these multiple data processing devices may be respectively used to independently implement different data processing functions. In the process of independently implementing their own data processing functions, these multiple data devices may perform statistical calculations on the same data metric (for example, data metric z1).

[0003] It can be seen that since these multiple data processing devices independently implement their own data processing functions, the above data metric z1 will be executed once by each of these multiple data processing devices, which will result in a waste of computing resources in the entire data processing system.

[0070] Next, the technical solutions in this application will be clearly and completely described in conjunction with the accompanying drawings in this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0071] Please refer to Figure 1 , Figure 1 It is a schematic structural diagram of a network architecture provided by an embodiment of this application. As Figure 1 shown, the network architecture may include a server cluster and a terminal device cluster. The terminal device cluster may include one or more terminal devices, and the number of terminal devices will not be limited here. As Figure 1 shown, the multiple terminal devices may specifically include terminal device 100a, terminal device 101a, terminal device 102a,..., terminal device 103a; the server cluster may include server 200,..., server 300. As Figure 1 shown, terminal device 100a, terminal device 101a, terminal device 102a,..., terminal device 103a can all be network-connected to each server in the server cluster, so that each terminal device can perform data interaction with each server through the network connection.

[0072] As Figure 1 shown, each server in the server cluster can be an independent physical server, or a server cluster or distributed system composed of multiple physical servers, 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, CDN, and big data and artificial intelligence platforms. The terminal device can be: intelligent terminals such as smart phones, tablet computers, notebook computers, desktop computers, and smart TVs.

[0073] Next, taking the communication between terminal device 100a, server 200, and server 300 as an example, the specific description of the embodiment of this application will be carried out.

[0074] Please refer to Figure 2 , Figure 2This is a schematic diagram of a scenario for obtaining service-consuming assets provided by this application. As Figure 2 shown, server 200 can be a server for calculating the service-consuming assets of target user 107b for the virtual assets held by the user. Server 300 can be a server for reconciling the transactions of all users (including target user 107b) for virtual asset objects. Among them, server 200 can be the first data device in the corresponding Figure 3 embodiment, and server 300 can be the second data device in the corresponding Figure 3 embodiment. For the specific descriptions of server 200 and server 300, refer to the respective steps in the corresponding Figure 3 embodiment.

[0075] Server 300 also includes asset data table 102b. Asset data table 102b includes the held asset objects belonging to each user (including target user 107b) and the virtual assets held by each user for the held asset objects after server 200 has completed the reconciliation of the transactions of all users for virtual asset objects. Among them, the held asset object belonging to a user is the virtual asset object purchased by the user, and the virtual asset object can refer to virtual assets such as funds or stocks. The virtual assets held by a user for the held asset object belonging to the user are the purchase quantity (i.e., the purchase share) of the user for the held asset object belonging to the user. Among them, the held asset object purchased by target user 107b can be recommended by the wealth management platform for target user 107b to purchase. Therefore, target user 107b needs to pay the corresponding service fee to the wealth management platform, and this service fee is the service fee of target user for the held asset object belonging to the user. Server 200 and server 300 above can be understood as the background servers of this wealth management platform.

[0076] Server 200 and server 300 are physically isolated from each other, that is, server 200 and server 300 do not belong to the same server, and the data between server 200 and server 300 is not shared but isolated from each other. Therefore, first, server 200 can request server 300 to obtain the isolation access permission for asset data table 102b in server 300. After server 300 receives the access permission acquisition request of server 200 for the asset data table, server 300 can set the isolation access permission for asset data table 102b for server 200. Among them, for the specific process of how server 200 obtains the isolation access permission for asset data table 102b from server 300, refer to step S101 in the corresponding Figure 3 embodiment.

[0077] After the server 200 obtains the isolation access right to the asset data table 102b from the server 300, it can access the asset data table 102b in the server 300, and obtain from the accessed asset data table 102b the held asset objects 103b of the target user 107b, as well as the virtual assets held by the target user for the held asset objects 103b to which the target user belongs.

[0078] As Figure 2 shown, the held asset objects 103b of the target user 107b obtained by the server 200 here specifically include held asset object 1, held asset object 2, held asset object 3, held asset object 4, and held asset object 5. The virtual assets held by the target user 107b for the held asset objects to which the target user belongs obtained by the server 200 specifically include: the virtual asset 1 held by the target user 107b for the held asset object 1, the virtual asset 2 held by the target user 107b for the held asset object 2, the virtual asset 3 held by the target user 107b for the held asset object 3, the virtual asset 4 held by the target user 107b for the held asset object 4, and the virtual asset 5 held by the target user 107b for the held asset object 5.

[0079] The server 200 can also obtain the service consumption factors for the held asset objects to which the target user 107b belongs. The service consumption factor is other relevant factors in addition to being related to the virtual assets held by the target user 107b for the held asset objects to which the target user belongs when calculating the service consumption assets of the target user 107b for the held asset objects to which the target user belongs. Here, the server 200 can obtain the service consumption factor 1 for the held asset object 1 of the target user 107b, the service consumption factor 2 for the held asset object 2 of the target user 107b, the service consumption factor 3 for the held asset object 3 of the target user 107b, the service consumption factor 4 for the held asset object 4 of the target user 107b, and the service consumption factor 5 for the held asset object 5 of the target user 107b. Among them, the specific description of the service consumption factor can also be referred to in step S104 in the corresponding Figure 3 embodiment below.

[0080] Subsequently, the server 200 can calculate the held service consumption assets of the target user 107b for each held asset object to which the target user belongs through the virtual assets held corresponding to each held asset object of the target user 107b and the service consumption factors obtained. The held service consumption assets of the target user for one of his held asset objects are the service fees of the target user 107b for the held asset object. The specific explanation of the held service consumption assets can also be referred to in the Figure 3 corresponding embodiment below.

[0081] Here, as shown in block 105b, the server 200 can calculate the holding service consumption asset 1 of the holding asset object 1 based on the holding virtual asset 1 and the service consumption factor 1; the server 200 can calculate the holding service consumption asset 2 of the holding asset object 2 based on the holding virtual asset 2 and the service consumption factor 2; the server 200 can calculate the holding service consumption asset 3 of the holding asset object 3 based on the holding virtual asset 3 and the service consumption factor 3; the server 200 can calculate the holding service consumption asset 4 of the holding asset object 4 based on the holding virtual asset 4 and the service consumption factor 4; the server 200 can calculate the holding service consumption asset 5 of the holding asset object 5 based on the holding virtual asset 5 and the service consumption factor 5.

[0082] Subsequently, the server 200 can sum up the above-obtained holding service consumption asset 1, holding service consumption asset 2, holding service consumption asset 3, holding service consumption asset 4, and holding service consumption asset 5 to obtain the service consumption asset 106b. The service consumption asset 106b is the service fee of the target user for all the holding asset objects to which the target user belongs.

[0083] As can be seen from the above, since the server 300 will obtain the holding virtual assets of the target user for the holding asset objects to which the target user belongs when reconciling the transactions of the target user for the virtual asset objects, the server 200 can directly obtain the isolated access permission for the asset data table from the server 300, and then, based on the obtained isolated access permission for the asset data table, obtain the holding virtual assets of the target user for the holding asset objects to which the target user belongs from the server 300, without the need to pull the transaction data of the target user for the virtual asset objects to re-obtain the holding virtual assets of the target user for the holding asset objects to which the target user belongs. Therefore, through the method provided in this application, the efficiency of the server 200 in obtaining the holding virtual assets of the target user for the holding asset objects to which the target user belongs can be improved, and further, the efficiency of the server 200 in calculating the service consumption assets of the target user for the holding asset objects to which the target user belongs can be improved.

[0084] Please refer to Figure 3 , Figure 3 which is a schematic flowchart of a virtual asset data processing method provided in this application. As Figure 3 shown, the method may include:

[0085] Step S101, based on the isolated access permission for the asset data table in the second data device, obtain the access storage address of the asset data table in the second data device; the first data device and the second data device are in a state of physical isolation from each other;

[0086] Specifically, the embodiments of the present application can be executed by a first data device, which can be a server or a terminal device. The first data device and the second data device are physically isolated from each other. In other words, the first data device and the second data device are not the same device and are independent devices. The second data device can also be a server or a terminal device.

[0087] Among them, the virtual asset object held by the target user can be called the holding asset object to which the target user belongs, and the share of the target user in the holding asset object to which the target user belongs can be called the holding virtual asset of the target user in the holding asset object to which the target user belongs. The holding asset object of the target user can be a virtual asset object such as stocks or funds purchased by the target user, and the holding virtual asset (i.e., share) of the target user in the holding asset object is the quantity of the holding asset object purchased by the target user.

[0088] For example, if the target user purchases 50 shares of stock 1, the holding virtual asset to which the target user belongs can be stock 1, and the holding virtual asset of the target user in stock 1 is 50 shares.

[0089] Among them, the above-mentioned first data device and the second data device can be the back-end of a wealth management platform, and the holding virtual object purchased by the target user can be recommended by the wealth management platform for the target user to purchase. Therefore, after the target user purchases the virtual asset object recommended by the wealth management platform, the wealth management platform can charge service fees from the target user. This process can be described in another way, that is, the wealth management platform can provide investment consulting (investment advisor) services to the target user (i.e., recommend virtual assets that can be purchased to the target user). After the target user accepts the investment consulting services provided by the wealth management platform, the target user needs to pay service fees for the investment consulting services to the wealth management platform. The service fees that the target user needs to pay to the wealth management platform can be called the service consumption assets of the target user for the holding asset object.

[0090] Therefore, it should be noted that the first data device can be a device for calculating the service consumption assets of the target user for the holding asset object to which the target user belongs. The second data device can be a device for reconciling the transactions of the target user for the virtual asset object (such as transactions for redeeming virtual assets or purchasing virtual assets). Since the first data device and the second data device are physically isolated from each other, it can be understood that the data stored in the first data device and the data stored in the second data device are isolated from each other.

[0091] Among them, when the first data device calculates the service consumption assets of the target user for the held asset object to which the target user belongs, it needs to calculate through the virtual assets held by the target user for the held asset object to which the target user belongs (i.e., asset shares). When the second data device reconciles the transactions of the target user for the virtual asset object, it will obtain the virtual assets held by the target user for the held asset object to which the target user belongs. Therefore, the first data device can request access rights to the second data device, so that the first data device can directly obtain from the second data device the virtual assets held by the target user for the held asset object to which the target user belongs.

[0092] Among them, for a better understanding of this embodiment, the process by which the second data device reconciles the transactions of the target user for the virtual asset object to obtain the virtual assets held by the target user for the held virtual assets may be as follows:

[0093] Since the second data device needs to reconcile the transactions of the target user for the virtual asset object every day, and the principle of the second data device reconciling the transactions of the target user for the virtual assets every day is the same, the process of the second data device reconciling the transactions of the target user for the virtual asset object on the Dth day is taken as an example for description here. Please refer to the following.

[0094] Since it can be confirmed that all the transactions of the target user on the Dth day have been completed at the end of the Dth day (i.e., the early morning of the D + 1th day), the second data device can reconcile the transactions of the target user for the virtual assets on the Dth day in the early morning of the D + 1th day: The second data device can obtain the virtual assets held by the target user for the held asset object to which the target user belongs on the D - 1th day. The second data device can also reconcile with the institutions with which the target user has transacted on the Dth day (such as the institutions to which the purchased or redeemed virtual assets belong). During the reconciliation process, the second data device can update the virtual assets held by the target user for the held asset object to which the target user belongs on the D - 1th day according to the transactions made by the target user on the Dth day. After all the transactions are reconciled, the virtual assets held by the target user for the held asset object to which the target user belongs on the Dth day can be obtained.

[0095] For example, if the virtual assets held by the target user for the held asset object 1 on the D - 1th day are 100 shares, and the target user purchases another 50 shares of the held asset object 1 on the Dth day, then at the end of the Dth day, the virtual assets held by the target user for the held asset object 1 will be 150 shares.

[0096] Among them, since the target user can conduct transactions on virtual asset objects every day, the held asset objects to which the target user belongs every day can be different, and the virtual assets held for the held asset objects to which the target user belongs can also be different. Therefore, when the second data device obtains the virtual assets held by the target user for the held asset objects to which the target user belongs, it is to obtain the held asset objects of the target user for each day and the virtual assets held for the held asset objects.

[0097] Among them, the data after reconciling the transactions of the target user on virtual asset objects by the second data device can be stored in the asset data table in the second data device. Therefore, the first data device only needs to provide the second data device with the access right to the asset data table, and the access right of the first data device to the asset data table in the second data device can be called the isolated access right.

[0098] Among them, the process by which the first data device obtains the isolated access right to the asset data table from the second data device can be as follows: The first data device can generate a permission acquisition request for the asset data table. This permission acquisition request is the request for the first data device to obtain the isolated access right to the asset data table from the second data device. This permission acquisition request can carry the device identifier (i.e., device ID) of the first data device and the data table identifier of the asset data table.

[0099] The first data device can send the generated permission acquisition request to the second data device. After obtaining the permission acquisition request, the second data device can obtain the device identifier of the first data device and the data table identifier of the asset data table from the permission acquisition request. The second data device can identify the device identity of the first data device according to the obtained device identifier of the first data device. A device list (which can be imported by developers) can be pre-imported into the second data device. This device list can include the device identifiers of multiple devices. The second data device can give the isolated access right to the asset data table to the devices that exist in this device list.

[0100] Therefore, developers can pre-add the device identifier of the first data device to this device list. Therefore, after the second data device detects the device identifier of the first data device in the permission acquisition request and detects that the device identifier of the first data device exists in the device list, it indicates that the second data device has successfully identified the device identity of the first data device. After the second data device successfully identifies the device identity of the first data device, it can find the asset data table according to the data table identifier of the asset data table in the permission acquisition request, and then set the isolated access right to the found asset data table for the first data device.

[0101] After obtaining the isolation access right to the asset data table in the second data device, the first data device can obtain the storage address of the asset data table in the second data device based on the isolation access right to the asset data table. The storage address of the asset data table in the second data device can be referred to as the access storage address.

[0102] Furthermore, the first data device and the second data device can also be blockchain nodes belonging to different blockchain networks. For example, the first data device can be a blockchain node belonging to the first blockchain network, and the second data device can be a blockchain node belonging to the second blockchain network. Therefore, it can be known that since the first data device and the second data device are blockchain nodes belonging to different blockchain networks, the data in the first data device and the data in the second data device are also isolated from each other.

[0103] Since the first data device needs to obtain the virtual assets held by the target user for the held asset objects in the asset data table of the second data device, the first data device and the second data device need to perform cross-chain interaction.

[0104] Among them, the cross-chain interaction between the first data device and the second data device can be achieved through smart contracts. A first smart contract can be constructed in the first data device, and this first smart contract is used for the first data device to send an access request for the asset data table to the second data device. A second smart contract can also be constructed in the second data device, and this second smart contract is used to respond to and execute the access request for the asset data table from the first data device. Among them, the first smart contract and the second smart contract can be interconnected. The second smart contract can identify the contract type of the first smart contract and respond to the access request for the asset data table initiated based on the first smart contract. Similarly, the first smart contract can also identify the contract type of the second smart contract and receive the data synchronized based on the second smart contract.

[0105] It should be noted that the above-mentioned first smart contract and second smart contract are used to achieve cross-chain interaction between the first data device and the second data device. However, for the first data device to access the second data device, it still needs the isolation access right to the asset data table. Therefore, the first data device can send a storage address acquisition request for the asset data table to the second data device through the first smart contract and the isolation access right to the asset data table in the second data device. The first data device sending a storage address acquisition request for the asset data table to the second data device is also initiating an access right for the asset data table to the second data device.

[0106] After obtaining the storage address access request sent by the first data device, the second data device can parse the storage address access request through a second smart contract. By parsing the storage address access request, the second data device can obtain the access storage address indicated by the storage address access request, which is the storage address of the asset data table in the second data device. For example, the data table identifier of the asset data table can be carried in the storage address acquisition request, and the access storage address indicated by the storage address acquisition request is the access storage address of the asset data table indicated by the data table identifier in the storage address acquisition request.

[0107] The second data device can send the access storage address of the asset data table obtained according to the storage address acquisition request to the first data device through the second smart contract, and the first data device can receive the access storage address sent by the second data device through the second smart contract through the first smart contract.

[0108] Step S102: Traverse the asset objects in the asset data table based on the access storage address and the user identifier of the target user to obtain the held asset objects to which the target user belongs;

[0109] Specifically, after obtaining the access storage address for the asset data table, the first data device can traverse the asset objects in the asset data table based on the access storage address and the user identifier of the target user. By traversing the asset objects in the asset data table, the held asset objects of the target user can be screened out from the asset data table. Since the first data device also needs to calculate the service consumption assets of the held virtual assets of the target user for the held asset objects to which the target user belongs every day, the held asset objects to which the target user belongs obtained by the first data device here are the held asset objects of the target user at the current latest.

[0110] For example, if the first data device needs to calculate the held virtual assets of the target user for the held asset objects to which the target user belongs on the Dth day, the held asset objects to which the target user belongs obtained by the first data device here can be the held asset objects to which the target user finally belongs on the Dth day obtained by the first data device at the early morning of the (D + 1)th day.

[0111] Since the holding asset object to which the target user belongs obtained by the first data device needs to be the final holding asset object of the target user after the second data device completes the transaction reconciliation of the target user for the virtual asset object on the same day (i.e., the day when the service consumption assets need to be calculated, such as the above-mentioned Day D). Therefore, before traversing the asset data table, the first data device also needs to determine the reconciliation status of the second data device for the target user's transaction of the virtual asset object. If the reconciliation status is the completed reconciliation status, it indicates that the asset data table has been updated with the target user's final holding asset object on the same day. Therefore, at this time, the first data device can traverse the asset data table according to the user identifier of the target user to obtain the target user's final holding asset object on the same day.

[0112] For example, first, the first data device can determine the process reconciliation status of the second data device for the asset reconciliation process in the asset data table based on the access storage address of the asset data table. The asset reconciliation process refers to the process of the second data device reconciling the holding asset object belonging to the target user in the asset data table. When the first data device determines that the process reconciliation status of the second data device for this asset reconciliation process is the completed reconciliation status, it indicates that the second data device has completed the update of the target user's final holding asset object on the same day in the asset data table. At this time, the first data device can traverse the asset data table according to the user identifier of the target user to obtain the target user's final holding asset object on the same day.

[0113] Furthermore, the virtual asset object recommended by the wealth management platform for the target user to purchase can also be an investment portfolio plan, which can include multiple asset objects (the virtual asset object can be simply referred to as an asset object). Therefore, there can be multiple holding asset objects to which the target user belongs. Specifically, the first data device can first package and encapsulate the access storage address of the asset data table and the user identifier of the target user to generate access information for accessing the asset data table, and this access information includes the access storage address of the asset data table and the user identifier of the target user. The first data device can access the asset data table through the access storage address in the access information. After successfully accessing the asset data table, it can traverse the virtual asset objects in the accessed asset data table according to the user identifier of the target user in the access information to traverse and filter out the combination of the target user's final holding asset objects on the same day. This combination of holding asset objects is the combination composed of multiple asset objects in the investment portfolio plan purchased by the target user. In other words, this combination of holding asset objects includes multiple holding asset objects to which the target user belongs. The first data device can use all the asset objects in the combination of holding asset objects as the currently obtained holding asset objects to which the target user belongs.

[0114] Through the above process, the first data device can obtain the held asset objects to which the target user belongs on the same day (the day for which service consumption assets need to be calculated, such as the above-mentioned Dth day).

[0115] Step S103: Obtain the virtual assets held by the target user for the held asset objects to which the target user belongs from the asset data table;

[0116] Specifically, after the second data device obtains the held asset objects to which the target user belongs on the same day in the asset data table, it can also obtain from the asset data table the virtual assets held by the target user for each held asset object to which the target user belongs on the same day, that is, obtain the holding shares corresponding to each held asset object respectively.

[0117] Step S104: Determine the service consumption assets of the target user for the held asset objects to which the target user belongs according to the virtual assets held by the target user for the held asset objects to which the target user belongs;

[0118] Specifically, the first data device can obtain the service consumption factors associated with each held asset object of the target user respectively. The service consumption factor refers to other relevant factors in addition to being related to the virtual assets held by the target user for the held asset objects when calculating the service consumption assets of the held asset objects to which the target user belongs. The first data device can calculate the service fees corresponding to each held asset object respectively through the service consumption factors associated with each held asset object of the target user respectively and the virtual assets held by the target user for each held asset object respectively, and the service fees corresponding to each held asset object respectively can be called the holding service consumption assets corresponding to each held asset object respectively.

[0119] The first data device can sum up the holding service consumption assets corresponding to each held asset object respectively, and then use the sum of the holding service consumption assets corresponding to each held asset object respectively as the service consumption assets of the target user for the held asset objects to which the target user belongs finally calculated.

[0120] For example, if among multiple (at least two) held asset objects of the target user there is a held asset object f n , where n is a positive integer less than or equal to the total number of assets of the multiple held asset objects of the target user, that is, the held asset object f n can be any one of the multiple held asset objects of the target user.

[0121] Therefore, the first data device can obtain the net asset value and asset rate of the held asset object f n , and the obtained net asset value and asset rate are the net asset value and asset rate associated with the held asset object f nAssociated service consumption factors. Then, the first data device can multiply the net asset value, the asset rate, and the virtual assets held by the target user for the asset object f n to obtain the product value of the net asset value, the asset rate, and the virtual assets held by the target user for the asset object f n . This product value is the service consumption assets held by the first data device for the target user for the asset object f n .

[0122] Every day, the first data device obtains the service fees for the asset objects held by the target user every day through the process described above. Moreover, the first data device can accumulate the service fees for the asset objects held by the target user obtained every day and charge the target user for the service fees once per quarter (it can also be other periods, specifically determined according to the actual application scenario).

[0123] Specifically, assuming that the above-obtained service consumption assets are the consumption assets (i.e., service fees) of the target user obtained by the first data device for the affiliated asset objects on the last day of a deduction cycle, then the consumption assets of the target user obtained by the first data device for the affiliated asset objects before that (every day except the last day of a deduction cycle) can be called historical consumption assets.

[0124] It can be said that the above service consumption assets are the consumption assets of the target user obtained by the first data device for the affiliated asset objects at the current moment. The current moment can refer to the final moment of the day to which the service consumption assets belong. For example, if the service consumption assets are the consumption assets of the target user calculated for the affiliated asset objects on the Dth day, then the current moment can be the final moment of the Dth day.

[0125] Similarly, the above historical consumption assets are the consumption assets of the target user obtained by the first data device for the affiliated asset objects at the historical moment. The historical moment can refer to the final moment of the day to which the historical consumption assets belong. For example, if the historical consumption assets are the consumption assets of the target user calculated for the affiliated asset objects on the Mth day, then the historical moment can be the final moment of the Mth day.

[0126] Therefore, when the above current moment meets the asset deduction cycle, the first data device can obtain the historical consumption assets of the target user for the affiliated asset objects at the historical moment. Among them, the current moment meeting the asset deduction cycle means that the current moment is the final moment of the last day of a deduction cycle, that is, the above service consumption assets are the consumption assets of the target user obtained by the first data device for the affiliated asset objects on the last day of a deduction cycle.

[0127] Next, the first data device can sum up the obtained historical consumption assets and service consumption assets, and the obtained sum value is the cumulative service consumption assets of the target user for the owned asset objects under a deduction cycle. This cumulative service consumption assets is the total service fee that the target user needs to pay within a deduction cycle.

[0128] Please refer to Figure 4 , Figure 4 which is a schematic diagram of a scenario for obtaining cumulative service consumption assets provided by this application. As Figure 4 shown, assume that a deduction cycle has n days, and these n days specifically include the 1st day, the 2nd day, ……, and the nth day of this deduction cycle. The first data device can calculate the service consumption assets of the target user for each day in these n days of this deduction cycle through the above process. Please refer to the following.

[0129] As Figure 4 shown, the owned asset objects of the target user on the 1st day may include owned asset object 1, owned asset object 2, and owned asset object 3. The owned virtual asset of the target user for owned asset object 1 on the 1st day may be owned virtual asset a1, the owned virtual asset of the target user for owned asset object 2 on the 1st day may be owned virtual asset b1, and the owned virtual asset of the target user for owned asset object 3 on the 1st day may be owned virtual asset c1.

[0130] Therefore, the first data device can calculate the owned service consumption asset fa1 of the target user for owned asset object 1 on the 1st day based on owned virtual asset a1; the first data device can calculate the owned service consumption asset fb1 of the target user for owned asset object 2 on the 1st day based on owned virtual asset b1; the first data device can calculate the owned service consumption asset fc1 of the target user for owned asset object 3 on the 1st day based on owned virtual asset c1. The first data device can sum up the owned service consumption assets fa1, owned service consumption asset fb1, and owned service consumption asset fc1, and then the service consumption asset 100c of the target user for all the owned asset objects on the 1st day can be obtained.

[0131] Similarly, the owned asset objects of the target user on the 2nd day may also include owned asset object 1, owned asset object 2, and owned asset object 3. The owned virtual asset of the target user for owned asset object 1 on the 2nd day may be owned virtual asset a2, the owned virtual asset of the target user for owned asset object 2 on the 2nd day may be owned virtual asset b1, and the owned virtual asset of the target user for owned asset object 3 on the 2nd day may be owned virtual asset c2.

[0132] Therefore, the first data device can calculate the holding service consumption assets fa2 of the target user for the holding asset object 1 on the second day based on holding the virtual asset a2; the first data device can calculate the holding service consumption assets fb1 of the target user for the holding asset object 2 on the second day based on holding the virtual asset b1; the first data device can calculate the holding service consumption assets fc2 of the target user for the holding asset object 3 on the second day based on holding the virtual asset c2. The first data device can sum up the holding service consumption assets fa2, the holding service consumption assets fb1, and the holding service consumption assets fc2, and then the service consumption assets 101c of the target user for all the holding asset objects to which the target user belongs on the second day can be obtained.

[0133] Similarly, the holding asset objects to which the target user belongs on the nth day can also include the holding asset object 1, the holding asset object 2, and the holding asset object 3. The virtual asset held by the target user for the holding asset object 1 on the nth day can be the virtual asset a2, the virtual asset held by the target user for the holding asset object 2 on the nth day can be the virtual asset b2, and the virtual asset held by the target user for the holding asset object 3 on the nth day can be the virtual asset c3.

[0134] Therefore, the first data device can calculate the holding service consumption assets fa2 of the target user for the holding asset object 1 on the nth day based on holding the virtual asset a2; the first data device can calculate the holding service consumption assets fb2 of the target user for the holding asset object 2 on the nth day based on holding the virtual asset b2; the first data device can calculate the holding service consumption assets fc3 of the target user for the holding asset object 3 on the nth day based on holding the virtual asset c3. The first data device can sum up the holding service consumption assets fa2, the holding service consumption assets fb2, and the holding service consumption assets fc3, and then the service consumption assets 102c of the target user for all the holding asset objects to which the target user belongs on the nth day can be obtained.

[0135] Through the above process, the first data device can calculate the service consumption assets of the target user for all the holding asset objects to which the target user belongs every day within a deduction cycle. The first data device can sum up the service consumption assets corresponding to each day within a deduction cycle, and then the final cumulative service consumption assets 103c of the target user within a deduction cycle can be obtained.

[0136] The first data device can generate an asset deduction prompt message according to the above cumulative service consumption assets. The asset deduction prompt message contains the cumulative service consumption assets that the target user needs to pay.

[0137] Moreover, the number of the above-mentioned historical consumption assets can be multiple, one corresponding to each day, that is, one corresponding to each historical moment. The first data device can also generate unit row description information corresponding to each historical consumption asset and the above-mentioned service consumption asset respectively. The unit row description information corresponding to one consumption asset may include the consumption asset.

[0138] The first data device can sort the unit row description information corresponding to each historical consumption asset and the above-mentioned service consumption asset respectively according to the chronological order of the historical moment corresponding to each historical consumption asset and the current moment corresponding to the service consumption asset. The one with an earlier time (historical moment and current moment) is sorted later, and the one with a later time is sorted earlier. By sorting the unit row description information corresponding to each historical consumption asset and the above-mentioned service consumption asset respectively, a unit row sequence can be obtained, and this unit row sequence includes the unit row description information corresponding to each historical consumption asset and the above-mentioned service consumption asset respectively.

[0139] The first data device can perform table rendering on the obtained unit row sequence to obtain table description information including the unit row sequence. This table description information is a table, and one row in this table is a unit row description information.

[0140] Please refer to Figure 5 , Figure 5 which is a schematic diagram of a scenario for generating table description information provided by this application. As Figure 5 shown, the unit row description information generated here may include unit row description information 100d, unit row description information 101d, unit row description information 102d, unit row description information 103d, unit row description information 104d, unit row description information 105d, unit row description information 106d, and unit row description information 107d. The first half of each unit row description information represents the date of the day to which the corresponding service consumption asset belongs, and the second half of each unit row description information represents the corresponding service consumption asset. For example, the first half of the unit row description information 100d, "2020-01-08", indicates that the date of the day to which the service consumption asset corresponding to the unit row description information 100d belongs is January 8, 2020. The second half of the unit row description information 100d, "0.0002", indicates that the service consumption asset corresponding to the unit row description information 100d is 0.0002.

[0141] Among them, the historical moment or the current moment corresponding to each unit line description information can be simply referred to as the moment corresponding to each unit line. Here, the moment corresponding to the unit line description information 100d is t1, the moment corresponding to the unit line description information 101d is t2, the moment corresponding to the unit line description information 102d is t3, the moment corresponding to the unit line description information 103d is t4, the moment corresponding to the unit line description information 104d is t5, the moment corresponding to the unit line description information 105d is t6, the moment corresponding to the unit line description information 106d is t7, and the moment corresponding to the unit line description information 107d is t8.

[0142] As shown in the time axis 109d, the moment corresponding to t3 is earlier than the moment corresponding to t4, the moment corresponding to t4 is earlier than the moment corresponding to t7, the moment corresponding to t7 is earlier than the moment corresponding to t8, the moment corresponding to t8 is earlier than the moment corresponding to t6, the moment corresponding to t6 is earlier than the moment corresponding to t5, the moment corresponding to t5 is earlier than the moment corresponding to t2, and the moment corresponding to t2 is earlier than the moment corresponding to t1.

[0143] Therefore, according to each unit line description information, the order of sorting the unit line description information 100d, the unit line description information 101d, the unit line description information 102d, the unit line description information 103d, the unit line description information 104d, the unit line description information 105d, the unit line description information 106d, and the unit line description information 107d from front to back is: the unit line description information 100d, the unit line description information 101d, the unit line description information 104d, the unit line description information 105d, the unit line description information 107d, the unit line description information 106d, the unit line description information 103d, and the unit line description information 102d. This order is also the order of each unit line description information in the unit line sequence. Therefore, the table description information obtained according to the unit line sequence is the table description information 109d. The order of each unit line description information in the table description information 109d is also the order of each unit line description information in the unit line sequence.

[0144] The first data device can generate an asset deduction prompt message according to this table description information. In other words, the asset deduction prompt message can also include this table description information, and this table description information shows the consumed assets (i.e., service fees) of the target user for the held asset objects belonging to the target user every day within a deduction cycle.

[0145] The first data device can also send the generated asset deduction prompt message to the user terminal to which the target user belongs (for example, the terminal device on which the target user logs in to the financial management platform). The user terminal to which the target user belongs can output the asset deduction prompt message on the terminal page, and the output method can be the page display method or the voice broadcast method.

[0146] Among them, the user terminal to which the target user belongs can also respond to the confirmation operation of the target user for the asset deduction prompt information in the terminal page, and deduct the cumulative assets of service consumption that the target user needs to pay from the asset account of the target user.

[0147] Please refer to Figure 6 , Figure 6 which is a page schematic diagram of a terminal page provided by this application. As Figure 6 shown, the terminal device 102e is the user terminal of the target user, and the information displayed in the investment advisor service fee details page shown in the terminal page 100e of the terminal device 102e is the above-mentioned asset deduction prompt information. The asset deduction prompt information may include the table description information 109d obtained in the above Figure 5 .

[0148] In the area 101e of the terminal page 100e, specific deduction details are displayed, including the withdrawn product, withdrawal time, fund destination, and withdrawal amount. Among them, the withdrawal amount 15.34 in the area 101e is the cumulative assets of service consumption that the user needs to pay in the above-mentioned one cycle. The terminal device 102e can respond to the confirmation operation of the target user for the asset deduction prompt information in the terminal page 100e, and deduct 15.34 from the user account of the target user.

[0149] It can be seen from this that when calculating the service consumption assets of the target user for the held asset object to which the target user belongs, the first data device proposed by this application can directly obtain the held asset object to which the target user belongs and the held virtual assets of the target user for this held asset object from the second data device based on the isolated access permission to the asset data table. Therefore, the first data device can quickly calculate the service consumption assets of the target user for the held asset object to which the target user belongs based on the held virtual assets of the target user for the held asset object to which the target user belongs obtained from the second data device.

[0150] In addition, since the first data device can directly obtain the held virtual assets of the target user for the held asset object to which the target user belongs in the second data device, without having to re-statistically calculate the held virtual assets of the target user for the held asset object to which the target user belongs, the utilization rate of the computing resources related to the held virtual assets of the target user for the held asset object to which the target user belongs in the system (including the relevant data processing systems of the first data device and the second data device) is improved, that is, the utilization rate of the computing resources related to the service consumption assets of the target user for the held asset object to which the target user belongs in the system is improved.

[0151] Please refer to Figure 7 , Figure 7 which is a schematic flowchart of a virtual asset data processing method provided by this application. The method may include:

[0152] Step S201, query whether the share reconciliation is completed;

[0153] Specifically, batch running can be understood as settlement, which is executed by the above-mentioned first data device. The reconciliation database is the above-mentioned asset data table, and the reconciliation database is in the second data device. The investment advisor share database and the investment advisor billing database both belong to the first data device. The investment advisor share database is used for the first data device to store the virtual assets held (i.e., shares) of the target user for the held asset object to which the target user belongs, which are obtained from the second data device. The investment advisor billing database is used for the first data device to store the cumulative value (i.e., total fee) of the service consumption assets of the target user for the held asset object to which the target user belongs, which is calculated every day within a cycle.

[0154] Here, if the first data device is to calculate the service consumption assets of the target user for the held asset object on the (D - 1)th day, the first data device can, based on the isolated access permission to the reconciliation database, query the second data device to check whether the transaction reconciliation of the target user for the virtual asset object on the (D - 1)th day is completed (i.e., query whether the share reconciliation is completed here).

[0155] Step S202, after completion, pull the reconciled shares of the user and save them;

[0156] Specifically, if the first data device queries that the share reconciliation of the target user on the (D - 1)th day in the reconciliation database is completed, the first data device can pull the reconciled shares of the user saved in the reconciliation database, and the reconciled shares of the user saved are the virtual assets held by the target user for the held asset object to which the target user belongs on the (D - 1)th day finally.

[0157] Step S203, record the shares held by the user on the (D - 1)th day;

[0158] Specifically, the first data device can store the virtual assets held by the target user for the held asset object to which the target user belongs on the (D - 1)th day finally, which are pulled, into the investment advisor share database.

[0159] Step S204, pull the shares held by the user on the (D - 1)th day;

[0160] Specifically, when the first data device starts to calculate the service consumption assets of the target user for the held asset object on the (D - 1)th day, the first data device can pull the virtual assets held by the target user for the held asset object to which the target user belongs on the (D - 1)th day finally, which were previously recorded, from the investment advisor share database.

[0161] Step S205, calculate the fee for D-1 day;

[0162] Specifically, the first data device can calculate the fee for the (D-1)th day by pulling the virtual assets held by the target user for the held asset object belonging to the user on the (D-1)th day (as well as the corresponding service consumption factors) from the investment advisor share database. The fee for the (D-1)th day is the service consumption assets of the target user for the held asset object belonging to the user on the (D-1)th day.

[0163] Step S206, record the billing details and update the total fee;

[0164] Specifically, the first data device can record the service consumption assets of the target user for the held asset object belonging to the user on the (D-1)th day in the investment advisor billing database and update the total fee. The total fee refers to the cumulative service fee of the target user for the held asset object belonging to the user up to now within the current deduction cycle. For example, if the (D-1)th day is the 3rd day within the current deduction cycle, the updated total fee includes the sum of the service consumption assets for the first 3 days of the current deduction cycle. Another example, if the (D-1)th day is the 5th day within the current deduction cycle, the updated total fee includes the sum of the service consumption assets for the first 5 days of the current deduction cycle. If the (D-1)th day is the last day within the current deduction cycle, the updated total fee is the cumulative service consumption assets for the current deduction cycle.

[0165] By adopting the method of the present application to associate the first data device and the second data device, the first data device can directly and quickly obtain the updated virtual assets held by the target user for the held asset object belonging to the user in the second data device, and quickly calculate the service consumption assets of the target user through the obtained virtual assets held by the target user for the held asset object belonging to the user, improving the calculation efficiency of the service consumption assets.
