Example 1
Referring to fig. 1, fig. 1 is a flowchart of a multi-type database adaptation method according to an embodiment of the present application, which includes the following steps:
s101: receiving a first type of operation instruction issued by a block chain network;
after receiving an operation instruction (referred to as a standard operation instruction in the present invention) issued by the blockchain network, determining a type of the operation instruction, wherein the first type may refer to any type, and the first type of operation instruction may be an operation instruction corresponding to an existing type of database or may be a custom operation instruction.
S102: detecting the type of a database actually installed in the current blockchain node equipment, and determining the type of an operation instruction which is suitable for the type of the database as a second type;
the type of database actually installed in the current blockchain node device is determined, the type of database that can be detected is referred to as the actual database type, and the type of operation instruction that is adapted to the actual database type is determined as the second type (relative to the standard operation instruction issued by the blockchain network, the second type of operation instruction may be referred to herein as the actual operation instruction) in order to effect the conversion of the operation instruction type, because the blockchain network cannot identify the second type of operation instruction used by the blockchain node when the first type is different from the second type on the same function of instructions, and the blockchain node cannot identify the first type of operation instruction that it receives until the database that is adapted to the first type of operation instruction is not installed.
Furthermore, if multiple types of databases are actually installed on the current blockchain node device, one of the most suitable types of databases can be selected as an actual database type according to actual conditions, and an operation instruction corresponding to the actual database type is determined as a second type. The specific manner may be based on the similarity between each type of operation instruction in describing the same function as the first type of operation instruction, all possible special requirements, etc., and is not specifically limited herein.
S103: converting the first type of operation instruction into the second type of operation instruction through a preset multi-type database adaptation rule;
based on S102, this step aims to complete the conversion from the first type to the second type (conversion from standard operation instruction to actual operation instruction) of the operation instruction through the preset multi-type database adaptation rule, so that the current block link point device can complete the task and related operation issued by the block chain network according to the converted operation instruction without installing the specific type of database. The multi-type database adaptation rule comprises a corresponding relation between a first type of operation instruction of each function and a second type of operation instruction of the same function of each type of database.
The adaptation rule may also be embodied as a special adaptation rule as shown in fig. 2 or a general adaptation rule as shown in fig. 3, depending on whether the first type of operation instruction is an existing operation instruction of a certain type.
FIG. 2 is a representation of an adaptation rule corresponding to a first type of operation as an existing type of operation instruction, i.e., a special adaptation rule is provided for a blockchain network requiring the use of a database of a certain type, and assuming that a blockchain network requires the use of a T-class operation instruction corresponding to a database of class X, then the same is true of providing an operation instruction conversion rule capable of converting the T-class operation instruction into an operation instruction recognizable by a plurality of other types of databases, i.e., a special adaptation rule is provided for the A blockchain network in a targeted manner, so that the database of class X no longer has to be installed in a node device as the A blockchain network to normally process the T-class operation instruction from the A blockchain network. However, in this case, once the other blockchain network that requires the use of the non-X type database is replaced, it is also necessary to provide an adaptation rule for adapting between the operation instruction type corresponding to the non-X type database and the other operation instruction types.
In consideration of that when the special adaptation rule is used, the special instruction conversion rule between each type of database and other types of databases needs to be created respectively, which is troublesome and is relatively responsible for management, a new operation instruction can be generated as a standard operation instruction according to the operation instruction types respectively used by the existing multiple types of databases, and when all blockchain networks apply the standard blockchain network, only the general adaptation rule created according to the correspondence between the standard operation instruction and other types of operation instructions needs to be provided (the correspondence contained in the general adaptation rule formed in this way can be seen in fig. 3). In other words, the standard operation instruction at this time is obtained after processing according to a plurality of existing operation instructions (corresponding to each type of database respectively), and the processing process is that is, the process of establishing the corresponding relationship, that is, the standard operation instruction at this time will be used as an upper operation instruction to send the operation instruction to the specific blockchain node device, and the general adaptation rule changes the operation instruction into the actual operation instruction corresponding to the type of the actual database through the corresponding relationship contained in the general adaptation rule, so as to achieve higher universality.
Under the condition that the standard operation instruction is generated according to the general adaptation rule, a database capable of directly processing the standard operation instruction without conversion does not exist, that is to say, the simple standard operation instruction does not have any meaning and is only used as a source operation instruction for determining the target operation instruction in the corresponding relation, so that the length of the standard operation instruction can be shortened as far as possible, the flow consumed in the data transmission process is reduced, and the information interaction efficiency is improved.
S104: and carrying out corresponding operation on the database through the second type of operation instruction.
According to the method and the device, the multi-type database adaptation rule comprising the corresponding relation between the first type of operation instruction (standard operation instruction) with each function and the second type of operation instruction (actual operation instruction) with the same function as each type of database is utilized, the first type of operation instruction (standard operation instruction) sent by the target blockchain network is converted into the second type of operation instruction (actual operation instruction) corresponding to the actual database, so that the database which cannot process the format originally can also perform corresponding operation according to the converted actual operation instruction, a user does not need to install the database of the specific type through a complex installation process again due to mismatching of the database types, the universality of the database is improved, and the user experience is improved.
Example two
Referring to fig. 4, fig. 4 is a flowchart of a general adaptation rule generating method provided in an embodiment of the present application, and on the basis of the first embodiment, the present embodiment aims to provide a general adaptation rule generating method without providing a respective special adaptation rule for each type of database, including the following steps:
s201: acquiring a second type of operation instruction which represents the same function in each type of database;
s202: generating a first type of operation instruction representing the same function according to the same or similar parts in each second type of operation instruction;
in order to make the first type of operation instruction (standard operation instruction) more relevant to the second type of operation instruction corresponding to the currently existing database type, the present embodiment generates the first type of operation instruction (standard operation instruction) representing the same function from the same or similar part of each second type of operation instruction.
S203: and establishing a corresponding relation between the first type of operation instruction of each function and the second type of operation instruction of the same function of the databases of various types, and generating a multi-type database adaptation rule according to each corresponding relation.
On the basis of S202, a correspondence may be easily established according to the process of searching for the same point, and a general adaptation rule may be generated according to each correspondence.
Under the mode of adopting general adaptation rule, firstly, a more superior operation instruction type with higher universality is required to be determined, and the original operation instruction type can be selected and also can be automatically established, when the self-establishment is adopted, the self-establishment can be combined with the position or meaning of the keyword in each existing operation instruction according to different modes, and the standard operation instruction obtained by the self-establishment cannot be directly processed by the existing various databases in the self-establishment mode, namely, the simple standard operation instruction has no meaning and is only used as the source operation instruction for determining the target operation instruction in the corresponding relation, so that the length of the operation instruction can be shortened as far as possible, the flow consumed in the data transmission process is reduced, and the information interaction efficiency is increased.
Example III
Referring to fig. 5, fig. 5 is a flowchart of a method for selecting a multi-type actual database in a multi-type database adaptation method provided in an embodiment of the present application, and on the basis of the foregoing embodiments, the embodiment provides a method for determining an actual type for a scenario in which a plurality of types of databases are installed in a current blockchain node, including the following steps:
s301: calculating the instruction similarity between the operation instructions corresponding to each type of database and the operation instructions of the first type respectively;
s302: the type of database with the highest instruction similarity is selected as the actual database type.
The instruction similarity represents the difference between the actual operation instructions of the databases of different types when the operation instructions of the same function are represented, the higher the similarity is, the smaller the difference between the two types of data is, the higher the coupling degree of the execution mode of the instructions is in the actual operation process, and the less error is likely to happen, so the embodiment selects the type of the database with the highest instruction similarity as the actual database type, and performs the conversion operation of the subsequent step according to the selected actual database type.
Because of the complexity and cannot be illustrated by one, those skilled in the art will recognize that many examples exist in accordance with the basic method principles provided herein in combination with actual situations, which are within the scope of the present application without significant inventive effort.
