Detailed Description
The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
With the continuous progress of metauniverse research in recent years, the variety and quantity of information supporting normal operation of metauniverse are exponentially increasing. As one of the metauniverse five-earth foundation techniques, the reliability of information storage is of great importance. At present, most of the metadata realizes data storage through an erasure code database, however, the erasure code technology storage mechanism is not perfectly matched with the operation mode of the metadata, the operation error rate is high, the recovery efficiency is low, the operation cost is huge, the flexibility is low, and the storage of massive data cannot be satisfied, so that the serious hidden danger is brought to the information support reliability of the metadata users. Therefore, the application provides a data read-write scheme, which can effectively improve the information transmission efficiency and flexibility of the metauniverse user and reduce the operation cost of the metauniverse database.
Referring to fig. 1, an embodiment of the present application discloses a data read-write method, which is applied to a first data storage layer in a preset meta-universe database, wherein the preset meta-universe database includes a plurality of data storage layers, and the method includes:
and S11, determining a corresponding target data storage layer and a corresponding target communication channel based on the read-write target storage level information corresponding to the current meta-universe character.
It should be understood that, in this embodiment, in order to meet the high-reliability storage requirement of the metauniverse user in the context of artificial intelligence and big data age, the preset metauniverse database adopts an element layering method, and the database storage array is layered into a plurality of data storage layers based on the metauniverse function, and the memory space scale of each layer can be set by the metauniverse developer according to the actual requirement, and is specifically divided into: a role layer (i.e., the first data storage layer), an experience layer (i.e., the second data storage layer), a discovery layer (i.e., the third data storage layer), a co-creation layer (i.e., the fourth data storage layer), and other user-defined levels. The unused data storage layers are connected by communication channels between layers, wherein each communication channel connects the role layer and other data storage layers in the pre-set meta-universe database, respectively. Therefore, the storage functions of the data storage layers are independent and do not interfere with each other, so that the information transmission efficiency and flexibility of a metauniverse user are improved to the greatest extent on the premise of ensuring the working reliability of the metauniverse system, and the system operation cost is reduced.
It is further understood that the internal roles of the metauniverse are divided into: biological people, electronic people, digital people, virtual people, information people. Each metauniverse user has a metauniverse character, and each character has different attributes. The character layer is a top data storage layer of the preset metauniverse database and is also a layer closest to the metauniverse character, the layer is decomposed into a plurality of small storage partitions, and each partition stores personal information of each character in the metauniverse, including but not limited to identity information, image information and social information of the character in the metauniverse. The character data stored in each small independent partition of the character layer can be set and modified according to the attribute of the metauniverse user, and each independent partition has a unique storage address for identifying the character and the user attribution of the current partition by the metauniverse database. In fig. 2, a (a 1 、A 2 And A is a 3 ）、B（B 1 、B 2 And B is connected with 3 ）、C（C 1 、C 2 And C 3 ）、D（D 1 And D 2 ）、E（E 1 And E is connected with 2 ) Representing the different roles of three biometric persons, three electronic persons, three digital persons, two virtual persons and two information persons and their corresponding storage partition locations, respectively.
The environment layer is used for storing information necessary for ecology and environment appearance of the current metauniverse, including but not limited to metauniverse natural environment information, ecology climate information, civilization system information, science and technology level information and social order information. The layer provides environment information for all roles in the current meta-universe, the access does not need to distinguish the types of the roles, the specific storage address is not needed, and the stored information is shared by all roles. The information stored by the environment layer can only be modified by the meta-universe development administrator, and the layer storage partition is a read-only attribute for all roles of the meta-universe.
The discovery layer stores economic and ecological information existing in the meta-universe, and in short digitizes the content or product created by the character in the meta-universe to obtain profits, including but not limited to the ecological information mainly including the production, vending and consumption of the character. The information of the layer is shared by roles, the roles can access and modify the economic and ecological information of the roles, and the economic and ecological information stored by each role in the layer is marked with the storage address of the current role in the layer of the roles, so that the meta space development manager can manage in an overall mode.
For the co-creation layer, the meta-universe has extremely strong co-creation and decentralization characteristics, namely, all roles can produce contents, and the meta-universe functions and ecological space are expanded. For this purpose, the information stored by the co-creation layer is provided by all roles together and marks the storage address of the information provider at the role layer. And after the output content is inspected by a meta-universe development manager, the meta-universe upgrading optimization operation corresponding to the information can be executed. The role co-creation information of the metauniverse is stored in a co-creation layer of a metauniverse database. Besides the necessary data storage hierarchy, the preset meta-universe database can expand more custom data storage layers according to other requirements of users.
Step S12, determining the read-write attribute corresponding to the target data storage layer to obtain corresponding target read-write attribute information; the read-write attributes include read-only attributes and readable-write attributes.
In this embodiment, after the target communication channel is determined as shown in fig. 3, since the function of the target communication channel is related to the target data storage layer, the read-write attribute of the target data storage layer needs to be determined to determine the operations that can be performed through the target communication channel.
Specifically, as shown in connection with fig. 2, each communication channel may be classified into a unidirectional channel (data bus is read/write only) and a bidirectional channel (data bus is read/write capable) according to each hierarchy attribute. The experience layer is of a read-only property, and the discovery layer and the co-creation layer are of a readable and writable property because the discovery layer is role-sharing and the information stored in the co-creation layer is provided by all roles. Similarly, the read-write properties of other data storage layers may be determined. Furthermore, for the unidirectional channel, for example, channel 1 connecting the role layer and the experience layer, the experience layer may also perform a corresponding data reading operation to the decision layer based on the channel 1. For the bi-directional channel, for example, channel 2 connecting the role layer and the discovery layer, the discovery layer may also perform a corresponding data read or data write operation based on the channel 2 to enable inter-layer information exchange.
And step S13, when the target read-write attribute information indicates that the target data storage layer is a readable-write attribute, jumping to a corresponding readable-write state, and executing corresponding data reading or data writing operation based on the local read-write requirement corresponding to the current meta-universe role and the target communication channel.
In conjunction with fig. 3, in this embodiment, when it is determined that the target communication channel is a bidirectional channel, it is first determined that a specific read-write requirement type is to be executed after the target communication channel is skipped to a readable-writable state, so that the executing corresponding data reading or data writing operation based on the local read-write requirement corresponding to the meta-space role and the target communication channel may specifically include: judging the local read-write requirements corresponding to the current meta-universe role to obtain a corresponding judging result; and executing corresponding data reading or data writing operation based on the judging result and the target communication channel.
Further, in one embodiment, the determining result indicates that the local read-write requirement corresponding to the meta-space character is a data read requirement, and then the local storage address of the meta-space character and the corresponding read instruction are sent to the target data storage layer through the address bus of the target communication channel. And then receiving corresponding data to be read fed back by the target data storage layer through the target communication channel, so as to verify, and finishing the data reading operation. In another embodiment, the judging result indicates that the local read-write requirement corresponding to the current metauniverse role is a data write requirement, and then the local storage address of the current metauniverse role and a corresponding write instruction are sent to the target data storage layer through the address bus of the target communication channel. And then writing corresponding data to be stored into the target data storage layer through the data bus of the target communication channel so as to complete the data reading operation. It should be understood that the preset meta-universe database has N-1 communication channels (where N is the number of data storage layers), where each communication channel includes 1 address bus with a bit width of a and 1 data bus with a bit width of d.
It should be further understood that, referring to fig. 4, in this embodiment, the preset metauniverse database and the control CPU (Central Processing Unit ) of the corresponding metauniverse database server together form a metauniverse database control terminal, and a metauniverse database development manager may manage and maintain the metauniverse database by using the corresponding preset metauniverse database development application software through the metauniverse database server.
For many users, different terminals (such as a computer, a wearable device, chip implantation and the like) can be used for calling multiple technologies (such as a blockchain, artificial intelligence, the internet of things, edge calculation, virtual reality technology and the like), and a control CPU (central processing unit) connected with the metauniverse database server through a network or a radio and the like can acquire user data (such as character data, environment data, economic ecological data and the like) stored in the preset metauniverse database, so that the application of the metauniverse data is realized.
Therefore, in the embodiment of the application, the first data storage layer in the preset meta-universe database firstly determines the corresponding target data storage layer and the corresponding target communication channel based on the read-write target storage level information corresponding to the current meta-universe role; then determining the read-write attribute corresponding to the target data storage layer to obtain corresponding target read-write attribute information; the read-write attribute comprises a read-only attribute and a readable-write attribute; and then when the target read-write attribute information indicates that the target data storage layer is a readable-write attribute, jumping to a corresponding readable-write state, and executing corresponding data reading or data writing operation based on the local read-write requirement corresponding to the current meta-universe role and the target communication channel. According to the application, the preset meta space database is hierarchically divided, and the target data storage layer and the corresponding target communication channel are determined when the first data storage layer reads and writes data, so that the information transmission efficiency and flexibility of the meta space user can be effectively improved and the operation cost of the meta space database can be reduced on the premise of ensuring the reliability when the data is read and written on the basis of the specific communication channel.
Referring to fig. 5, an embodiment of the present application discloses a data read-write method, which is applied to a first data storage layer in a preset meta-universe database, where the preset meta-universe database includes a plurality of data storage layers, and the method includes:
and S21, determining a corresponding target data storage layer and a corresponding target communication channel based on the read-write target storage level information corresponding to the current meta-universe character.
Step S22, determining the read-write attribute corresponding to the target data storage layer to obtain corresponding target read-write attribute information; the read-write attributes include read-only attributes and readable-write attributes.
Step S23, when the target read-write attribute information indicates that the target data storage layer is of a read-only attribute, jumping to a corresponding read-only state, and executing corresponding data reading operation based on the target communication channel.
Specifically, in this embodiment, when it is determined that the target communication channel is a unidirectional channel, the specific read-write request type is not required to be determined after the target communication channel jumps to the read-only state, and the corresponding data reading operation can be directly performed when there is a request. That is, the local storage address of the metauniverse role and the corresponding read instruction are first sent to the target data storage layer through the address bus of the target communication channel. And then receiving corresponding data to be read fed back by the target data storage layer through the target communication channel, so as to verify, and finishing the data reading operation.
For the specific process of steps S21 to S22, reference may be made to the corresponding content disclosed in the foregoing embodiment, and no further description is given here.
Therefore, in the embodiment of the application, when the first data storage layer in the preset meta-universe database reads and writes data, the corresponding target data storage layer and the corresponding target communication channel are determined based on the read-write target storage level information corresponding to the current meta-universe role; then determining the read-write attribute corresponding to the target data storage layer to obtain corresponding target read-write attribute information; the read-write attribute comprises a read-only attribute and a readable-write attribute; and then when the target read-write attribute information indicates that the target data storage layer is of a read-only attribute, jumping to a corresponding read-only state, and executing corresponding data reading operation based on the target communication channel. Thus, when the demand corresponding to the current metauniverse role exists for the target communication channel, the data reading operation can be directly executed, and the efficiency is improved.
