Embodiment 1

[0031] see figure 1 , figure 1 Shown is a schematic flowchart of a method for writing a relational database based on blockchain technology provided by the embodiment of the present application. A method for writing a relational database based on block chain technology, comprising the steps of: writing a plurality of rows of data into a block chain database respectively, and the above block chain database provides two intervention mechanisms for each write operation, one of which is One of the above-mentioned intervention mechanisms includes selecting one or more of the above-mentioned row data as readable items, and another above-mentioned intervention mechanism includes controlling whether the above-mentioned row data is allowed to be inserted.

[0032]In detail, the manner in which multiple rows of data are respectively written into the blockchain database can use any conventional choice in the prior art, and no specific description is necessary here. According to the bloc...

Embodiment 2

[0049] A schematic diagram of the principle of a relational database writing system based on blockchain technology provided by the embodiment of the present application. A relational database writing system based on blockchain technology, including a blockchain database, filters and triggers, the above-mentioned blockchain database is used to write row data multiple times through user requests, and for each write operation Two intervention mechanisms are provided, one of which includes selecting one or more of the above-mentioned row data as readable items, and the other above-mentioned intervention mechanism includes controlling whether the above-mentioned row data is allowed to be inserted; the above-mentioned filter is used to pass the write operation Realize the selection of one or more rows of data; the trigger is used to control whether the row of data is allowed to be inserted through a write operation.

[0050] In some embodiments of the present invention, the above-me...

Abstract

The invention provides a relational database writing method and system based on a block chain technology, and relates to the technical field of block chains. The relational database writing method based on the block chain technology comprises the following steps that: multiple pieces of line data are written into a block chain database, the block chain database provides two intervention mechanisms for each writing operation, one intervention mechanism comprises selecting one or more pieces of line data as readable items, and the other intervention mechanism comprises controlling whether the line data is allowed to be inserted. The invention further provides a relational database writing-in system based on the block chain technology. The relational database writing-in system based on the block chain technology is realized based on the relational database writing-in method based on the block chain technology.

Description

technical field [0001] The present invention relates to the field of block chain technology, in particular, to a method and system for writing relational databases based on block chain technology. Background technique [0002] A relational database is a database built on the basis of a relational database model. It uses concepts and methods such as set algebra to process data in the database. It is also a form organized into a set of formally descriptive tables. Is a special collection loaded with data items, the data in these tables can be accessed or recalled in many different ways without reorganizing the database tables. The definition of a relational database results in a table of metadata or in a formal description of tables, columns, scopes and constraints. Each table (sometimes called a relation) contains one or more data types represented by columns. Each row contains a unique data entity of the type defined by the column. [0003] For traditional relational data...
