Problems solved by technology

[0004] The purpose of the present invention is to improve the combination of ETL and blockchain, considering that the content of the blockchain is not easy to tamper with because it retains the business generation track, which is similar to the zipper table mode of ETL. To solve the problem that credible data governance is difficult to achieve in a large-scale distributed environment, a method and system for data credible data governance based on blockchain technology is proposed

Embodiment 1

[0049] The flow chart of a data credible data governance method based on blockchain technology is as follows: figure 1 shown, including the following steps:

[0050] A. After the original data is extracted, cleaned and converted, summary information corresponding to the data details is generated. The summary includes the timestamp of this operation, source database name or source data address, source table name, target database name or target database address, The name of the target table, the hash value of the data in this operation, the number of fields, the number of records, etc. The content of the summary information is as follows figure 2 shown. Along with the summary information, processed data details (that is, detailed data fields) are generated.

[0051] B. According to the data details, calculate the data hash value of this operation;

[0052] C. Store the summary information and data hash value on the chain;

[0053] D. Store the data details and data hash val...

Abstract

The invention discloses a data trusted data processing method and system based on a block chain technology in the technical field of data trusted processing. The method comprises the following steps:A, extracting, cleaning and converting original data to generate data details and abstract information corresponding to the data details; B, calculating a data hash value according to the data details; C, uploading and storing the abstract information and the data hash value; and D, storing the data details and the data hash values in a database under the chain. Using the method, abstract information generated in the data extraction and cleaning conversion process is uploaded to a block chain, the data is stored in a database under the chain, the relation between the under-chain data and the on-chain abstract information is established through the hash value and the record credible state, credibility management of the data is achieved through the storage mode, complexity caused by direct extraction conversion and up-chain operation on the original data is avoided, and efficient data governance work can still be conducted in a large-scale distributed environment.

Description

technical field [0001] The invention relates to the technical field of trusted data governance, and specifically discloses a trusted data governance method and system based on block chain technology. Background technique [0002] In most practices in the past 10 years, the basic idea of ​​data governance is data extraction and transformation, that is, ETL. Traditional ETL extracts data from the source database, and loads the cleaned data into the target database after a series of cleaning operations. Taking the original data extraction of the data warehouse as an example, the form of a zipper table is used to add updated data each time, adding the start and end time and valid status identification to each piece of data, and only incrementing without data deletion. After ETL processing, the newly added data is loaded into the data warehouse, and the data status is identified at the same time. This keeps the entire history of the data. [0003] For ETL, whether it is structu...
