Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the embodiments of the present invention will be described in further detail with reference to the accompanying drawings. The exemplary embodiments of the present invention and their descriptions herein are for the purpose of explaining the present invention, but are not to be construed as limiting the invention.
Fig. 1 shows an implementation flow of a blockchain-based database table processing method according to an embodiment of the present invention, and for convenience of description, only a portion relevant to the embodiment of the present invention is shown, which is described in detail below:
as shown in fig. 1, a blockchain-based database table processing method includes:
Step 101, when receiving a database table change request sent by the current source system 1104, determining an associated source system 1105 of the current source system 1104 according to an association relationship between database tables of the source system 1102; an association exists between the database table of the association source system 1105 and the database table of the current source system 1104;
102, associating the source system 1105 and the data management platform 1103 to perform consensus on a database table change request sent by the current source system 1104; the source system 1102 including the current source system 1104 and the associated source system 1105 and the data governance platform 1103 are both connected to the blockchain network 1101;
step 103, if the associated source system 1105 and the data management platform 1103 pass the database table change request sent by the current source system 1104, synchronously updating the database table change of the current source system 1104 to the associated source system 1105 and the data management platform 1103 through the blockchain network 1101.
In an embodiment of the present invention, source system 1102 includes current source system 1104 and associated source system 1105, and may include other source systems in addition to current source system 1104 and associated source system 1105. The current source system 1104 refers to a source system that sends a database table change request or a source system that needs to make a database table change. Wherein, there is an association (or dependency) between the database tables of the current source system 1104 and the database tables of the associated source system 1105, while there is no association between the database tables of the other source systems 1102 and the database tables of the current source system 1104.
In addition, the source system 1102 and the data governance platform 1103 are connected to the blockchain network 1101 by a protocol, that is, at least the current source system 1104, the associated source system 1105 and the data governance platform 1103 are connected to the blockchain network 1101 by a protocol, and other source systems 1102 are connected to the blockchain network 1101 by a protocol. The change of the database table may include a new addition, a deletion, or a modification of the database table structure, for example, a new addition, a deletion, or a modification of the database table structure.
When the database table synchronization is performed, the current source system 1104 sends a database table change request to the blockchain network 1101, and when the blockchain network 1101 receives the database table change request sent by the current source system 1104, the associated source system 1105 of the current source system 1104 is determined based on the association relationship between the database tables of the source system 1102. The association relationship between the database tables of each source system 1102 is pre-stored and configured, which indicates and reflects the association relationship between the database table of a certain source system and the database tables of another source system or systems. Preferably, the associations between database tables of the source system are configurable and stored in the blockchain network 1101.
Wherein, there is an association relationship between the database table of the current source system 1104 and the database table of the association source system 1105, that is, the database table having an association relationship with the database table of the current source system 1104 can be determined through the database table of the current source system 1104, and then the source system 1102 corresponding to the database table having an association relationship with the database table of the current source system 1104, that is, the association source system 1105, is determined based on the database table having an association relationship with the database table of the current source system 1104.
In view of the fact that there is a correlation between the current source system 1104 and the associated source system 1105 and the data management platform 1103, for example, a certain field of the database table of the current source system 1104 and a certain field of the database table of the associated source system 1105, the current source system 1104 needs to accurately transmit the database table to the data management platform 1103 under certain conditions, so that the change of the database table of the current source system 1104 affects the associated source system 1105 and the data management platform 1103, and therefore when receiving the database table change request sent by the current source system 1104, the associated source system 1105 and the data management platform 1103 need to commonly identify the database table change request sent by the current source system 1104. Allowing the current source system 1104 to make changes to the database table when the consensus passes; the current source system 1104 is not permitted to make changes to the database tables if the consensus fails.
Therefore, when the database table change request sent by the associated source system 1105 and the data management platform 1103 to the current source system 1104 passes through, the current source system 1104 is allowed to change the database table, and the database table change of the current source system 1104 is synchronously updated to the associated source system 1105 and the data management platform 1103 through the blockchain network 1101, so that the database table change of the source system 1102 is synchronized in other source systems 1102 and the data management platform 1103.
In the embodiment of the invention, when receiving a database table change request sent by the current source system 1104, determining an associated source system 1105 of the current source system 1104 according to the association relationship between database tables of the source system 1102; further, the associated source system 1105 and the data management platform 1103 perform consensus on the database table change request sent by the current source system 1104; if the consensus passes, then the changes to the database tables of the current source system 1104 are synchronously updated to the associated source system 1105 and the data administration platform 1103 via the blockchain network 1101. According to the embodiment of the invention, the association source system 1105 is determined based on the association relationship, when the association source system 1105 and the data management platform 1103 pass through the consensus, the current source system 1104 can perform database table change, and meanwhile, the database table change of the current source system 1104 can be effectively and synchronously updated to the association source system 1105 and the data management platform 1103 through the blockchain network 1101, so that the database table change synchronization among the current source system 1104, the association source system 1105 and the data management platform 1103 is realized.
Fig. 2 shows a flow of implementing step 101 in the blockchain-based database table processing method according to the embodiment of the present invention, and for convenience of description, only the portion relevant to the embodiment of the present invention is shown, which is described in detail below:
in an embodiment of the present invention, in order to improve the efficiency of determining the associated source system 1105, as shown in fig. 2, step 101, when receiving a database table change request sent by the current source system 1104, determines the associated source system 1105 of the current source system 1104 according to the association relationship between database tables of the source system 1102, including:
step 201, when receiving a database table change request sent by the current source system 1104, acquiring an association table from the blockchain network 1101; the association table comprises association between database tables of the source system 1102;
step 202, determining the associated source system 1105 of the current source system 1104 according to the association relationship between the database tables of the source system 1102 in the association relationship table.
In an embodiment of the present invention, the association between database tables of the source system 1102 may be pre-configured in an association table in the blockchain network 1101. In this way, when determining the association source system 1105 of the current source system 1104, only the association relationship table needs to be directly obtained from the blockchain network 1101, and then the association source system 1105 of the current source system 1104 is determined through the association relationship table.
Specifically, upon receiving the database table change request sent by the current source system 1104, an association table containing association relationships between database tables of each source system 1102 is obtained from the blockchain network 1101. Further, the source system 1102 corresponding to the database table having the association relationship with the database table of the current source system 1104, that is, the association source system 1105 is determined by determining the database table having the association relationship with the database table of the current source system 1104 and then based on the database table having the association relationship with the database table of the current source system 1104.
In the embodiment of the present invention, when receiving the database table change request sent by the current source system 1104, the association relationship table is obtained from the blockchain network 1101, and the association source system 1105 of the current source system 1104 is determined according to the association relationship between the database tables of the source system 1102 in the association relationship table, so that the efficiency of determining the association source system 1105 can be improved. Meanwhile, the association table configuration is stored in the blockchain network 1101, so that the accuracy of the association between database tables of the source system 1102 can be ensured.
Fig. 3 shows another implementation flow of the blockchain-based database table processing method according to the embodiment of the present invention, and for convenience of description, only the portion relevant to the embodiment of the present invention is shown, which is described in detail below:
In an embodiment of the present invention, in order to improve accuracy of the association table, as shown in fig. 3, based on the above method steps, the method for processing a database table based on a blockchain further includes:
step 301, when a configuration request of an association table is received, obtaining a consensus result of a source system 1102 in a blockchain network 1101;
in step 302, after the source system 1102 passes the configuration request consensus of the association table, the association table is configured into the blockchain network 1101.
In the embodiment of the invention, the association table can be configured in the blockchain network 1101 through the blockchain technology, so that the accuracy of the association table is improved. Meanwhile, the association relation between the database tables of the source system 1102 is configured in a manner of configuring the association relation table, so that the flexibility of adjusting the association relation between the database tables of the source system 1102 can be improved.
Specifically, when configuring the association table, firstly, a configuration request of the association table is received, and in view of the association between database tables of the source system 1102 reflected by the association table, each source system 1102 accessing the blockchain network 1101 performs consensus on the configuration request of the association table, and configures the association table in the blockchain network 1101 under the condition that the consensus passes.
In the embodiment of the invention, when receiving the configuration request of the association table, the consensus result of the source system 1102 in the blockchain network 1101 is obtained, and after the configuration request of the source system 1102 for the association table is consensus passed, the association table is configured in the blockchain network 1101, so that the accuracy of the association table can be improved, and meanwhile, the flexibility of adjusting the association between database tables of the source system 1102 can be improved.
In an embodiment of the present invention, in order to improve the accuracy of the database table of the source system 1102, as shown in fig. 3, the method for processing the database table based on the blockchain further includes:
in step 303, if the database table change request sent by the associated source system 1105 and the data management platform 1103 to the current source system 1104 fails to pass the consensus, the change of the database table of the current source system 1104 cannot be written into the blockchain network 1101.
In the embodiment of the present invention, the associated source system 1105 and the data management platform 1103 perform consensus on the database table change request sent by the current source system 1104, and if the consensus is not passed, the database table change of the current source system 1104 is refused to be written into the blockchain network 1101, that is, the database table is not allowed to be changed by the current source system 1104 at this time, so that the accuracy of the database table of the source system 1102 can be improved.
In the embodiment of the present invention, if the database table change request sent by the associated source system 1105 and the data management platform 1103 to the current source system 1104 fails to be known together, the change of the database table of the current source system 1104 cannot be written into the blockchain network 1101, so that the accuracy of the database table of the source system 1102 can be improved.
Fig. 4 shows a flow implemented in step 103 in the blockchain-based database table processing method according to the embodiment of the present invention, and for convenience of description, only the portions relevant to the embodiment of the present invention are shown, which are described in detail below:
in an embodiment of the present invention, in order to improve the accuracy of the synchronized database tables, as shown in fig. 4, step 103, if the database table change request sent by the associated source system 1105 and the data management platform 1103 to the current source system 1104 is commonly passed, the database table change of the current source system 1104 is synchronously updated to the associated source system 1105 and the data management platform 1103 through the blockchain network 1101, including:
step 401, if the associated source system 1105 and the data management platform 1103 pass the database table change request sent by the current source system 1104, the current source system 1104 writes the change of the database table into the blockchain network 1101;
In step 402, the blockchain network 1101 synchronously updates changes to the database tables of the current source system 1104 to the associated source system 1105 and the data administration platform 1103.
When the database table of the current source system 1104 is changed and synchronized to the associated source system 1105 and the data management platform 1103, if the database table change request sent by the associated source system 1105 and the data management platform 1103 passes through the database table change request, the current source system 1104 is allowed to change the database table, namely, the current source system 1104 writes the change of the database table into the blockchain network 1101 to ensure the accuracy of the database table, and then the blockchain network 1101 synchronously updates the change of the database table of the current source system 1104 to the associated source system 1105 and the data management platform 1103, thereby improving the accuracy of the database table synchronized to the associated source system 1105 and the data management platform 1103.
In the embodiment of the present invention, if the associated source system 1105 and the data management platform 1103 pass the database table change request sent by the current source system 1104, the current source system 1104 writes the change of the database table into the blockchain network 1101, and the blockchain network 1101 synchronously updates the change of the database table of the current source system 1104 to the associated source system 1105 and the data management platform 1103, so that the accuracy of the synchronized database table can be improved.
FIG. 5 shows a partial implementation flow of yet another blockchain-based database table processing method according to an embodiment of the present invention, and for convenience of description, only the portion relevant to the embodiment of the present invention is shown, which is described in detail below:
in an embodiment of the present invention, in order to improve the accuracy of the database table issued by the current source system 1104 to the data administration platform 1103, as shown in fig. 5, the blockchain-based database table processing method further includes:
step 501, when receiving a data issuing request sent by a current source system 1104, comparing a database table of the current source system 1104 with a database table of an associated source system 1105 in a blockchain network 1101, which has an association relationship with the database table of the current source system 1104;
step 502, if the database table associated with the database table of the current source system 1104 in the association source system 1105 in the blockchain network 1101 is inconsistent with the database table of the current source system 1104, updating the database table of the current source system 1104 according to the database table associated with the database table of the current source system 1104 in the association source system 1105;
in step 503, according to the data issuing request sent by the current source system 1104, the updated database table of the current source system 1104 is issued to the data management platform 1103 through the blockchain network 1101.
In an embodiment of the present invention, the database tables of the source system 1102 are all configured in the blockchain network 1101. Upon receiving a data issue request sent by the current source system 1104, in order to ensure the accuracy of the database table issued by the current source system 1104, the database table of the current source system 1104 is compared with the database table of the associated source system 1105 in the blockchain network 1101. The database table of the association source system 1105 refers to a database table having an association relationship with the database table of the current source system 1104.
If the database table of the current source system 1104 is consistent with the database table of the associated source system 1105 in the blockchain network 1101, indicating that the database table of the current source system 1104 is accurate, the database table of the current source system 1104 may be directly issued to the data administration platform 1103 by the blockchain network 1101.
If the database table of the current source system 1104 is inconsistent with the database table of the associated source system 1105 in the blockchain network 1101, the database table of the associated source system 1105 is generally accurate because the database table of the associated source system 1105 in the blockchain network 1101 is stored in the blockchain network after being agreed, which indicates that the database table of the current source system 1104 is inaccurate, the database table of the current source system 1104 cannot be directly issued to the data administration platform 1103 through the blockchain network 1101. At this time, the database table of the current source system 1104 needs to be updated based on the database table of the accurate associated source system 1105, so as to synchronize the database table content of the accurate associated source system 1105 to the database table of the current source system 1104, and after updating, based on the data issuing request, the updated database table of the current source system 1104 is issued to the data management platform 1103 through the blockchain network 1101.
