Embodiment 1

[0053] figure 1 is a flow chart of a metadata-based management method according to an exemplary embodiment, applied to a metadata management node, figure 1 The methods shown include:

[0054] Step 101: acquiring metadata processing information;

[0055] In an exemplary embodiment, the metadata management node may correspond to a terminal device or server used to manage data in a business field, wherein the metadata management node may be divided into: a metadata management front-end module and a management node back-end module, obtaining The metadata processing information may be the front-end module of the metadata management node, wherein the metadata is the description information of the data, and the metadata processing information may include: creating metadata, modifying metadata, deleting metadata, accessing metadata, Metadata traceability request.

[0056] Step 102: According to the processing information of the metadata, send the corresponding operation instruction...

Embodiment 2

[0101] Figure 7 is a flowchart of a metadata management method shown in Embodiment 2, which is applied to a metadata management node, Figure 7 The methods shown include:

[0102] Step 701: At least one metadata management node among multiple metadata management nodes acquires metadata processing information;

[0103] In an exemplary embodiment, each metadata management node can correspond to a terminal device or server used to manage data in a business field, wherein each metadata management node can be divided into: a metadata management front-end module and a management node rear The end module, which obtains metadata processing information can be the front-end module of the metadata management node, where the metadata processing information can include: creating metadata, modifying metadata, deleting metadata, accessing metadata, and requesting metadata traceability .

[0104] Step 702: According to the processing information of the metadata, send the corresponding ope...

Embodiment 3

[0111] Figure 8 It is a blockchain-based metadata management method shown in Embodiment 3, which is applied to blockchain. Such as Figure 8 As shown, the method includes:

[0112] Step 801: The metadata management contract module receives the corresponding operation instruction of the metadata processing information;

[0113] Step 802: Complete the operation corresponding to the processing information of the metadata on the blockchain according to the corresponding operation instruction.

[0114] In an exemplary embodiment, the metadata management contract module receives corresponding operation instructions for metadata processing information sent by the backend module of the metadata management node, and performs corresponding operations on the metadata processing information on the blockchain , the purpose is to store the metadata processing information of all metadata management nodes on the blockchain to ensure the consistency of metadata of all metadata management n...

Abstract

The invention discloses a block chain-based metadata management method and system, and a computer storage medium, and the method comprises the steps: obtaining the processing information of metadata;and according to the processing information of the metadata, sending a corresponding operation instruction and the metadata to a metadata management contract module, so as to complete an operation corresponding to the processing information of the metadata on the blockchain, and after an instruction capable of synchronizing the metadata on the blockchain to a local database is obtained, synchronizing the metadata on the blockchain to the local database. According to the technical scheme, the metadata can be managed in a decentralized mode, the authenticity of the metadata is guaranteed, the phenomena of data pollution and tampering are eradicated, and the metadata is managed and backed up through a plurality of service ends.

Description

technical field [0001] The present invention relates to the technical field of data management, in particular to a blockchain-based metadata management method, system and computer storage medium. Background technique [0002] With the growth of metadata volume and business needs, many requirements need to be completed by combining metadata of multiple enterprises or units. In this way, metadata is provided by all parties, that is, metadata is scattered within each organization, and data users cannot Ensure that the data used is authentic and reliable. The existing metadata management technologies are all aimed at the data management of databases or data warehouses. The current metadata management methods have the following disadvantages: [0003] 1. Centralized storage of metadata cannot guarantee authenticity and cannot be tampered with; [0004] 2. Single-point storage of metadata has a single-point problem, and the robustness of the system is low; [0005] 3. It is not ...
