Traceability application-oriented block chain database data management system and method

Abstract

The invention provides a traceability application-oriented blockchain database data management system, comprising: 1) an analysis and conversion component layer comprising a plurality of analysis andconversion components ARP to realize simple processing and analysis of BDQL statements; 2) a logic combination processing layer, which is used for realizing recombination of statements; 3) a data driving layer converting data into a data format required by the BCD driver, wherein the data is sent to the BCD driver after being processed by the logic processing layer, and the BCD driver converts thedata format into BCD executable data BED and sends the BCD executable data BED to the data storage layer; and 4) a data storage layer for storing data. The invention discloses a traceability application-oriented block chain database data management method. The method comprises the steps of block chain database BDQL language conversion and data query, insertion and updating operation in a block chain database through BDQL. According to the system and the method, the data format is converted, the standardized operation is completed, a developer directly inputs SQL-like statements, and the BCD of the block chain database is added, modified and checked through the BDQL.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a traceability application-oriented blockchain database data management system and method. Background technique [0002] Blockchain refers to a chained data structure that combines many blocks that store data in chronological order. It uses cryptography to ensure that data cannot be tampered with, and uses distributed storage to ensure data security and use. The consensus mechanism is used to ensure the validity of the data, and the smart contracts composed of automated script codes are used to realize data processing and related business operations. [0003] Traceability refers to the traceability of the entire life cycle of the processing object to monitor the entire process, find problems and trace them back to the specific responsible person. However, the current pain points of traceability are: centralized data storage, there is a risk that the intermediate management par...

AI Technical Summary

Problems solved by technology

[0006] 1. NoSQL non-relational databases are usually used and do not support SQL standards;

[0007] 2. The query process is complicated;

[0008] 3. System maintenance is difficult;

[0009] 4. Data display is difficult

[0010] For example, BigchainDB is more complicated to use for developers and data management clients, and it is not easy to be compatible with other systems. It is difficult for developers to use and operate, and the learning cycle is long.
