Abstract

The invention discloses a method for supplementing metadata description. The method comprises the following steps: obtaining pre-stored full metadata from each source database; performing data blood relationship analysis on the full metadata to construct a blood relationship map among different data tables of the full metadata; obtaining a target field to be complementarily described from the full-scale metadata, and determining a target table to which the target field belongs; determining an upstream table of the target table according to the blood relationship map; and analyzing the similarity between the metadata field in the upstream table and the target field, and carrying out supplementary description on the target field according to the similarity. The invention further discloses adevice and equipment for supplementing metadata description and a storage medium. According to the method, in the process of supplementing metadata description, manual intervention is reduced, the labor cost is reduced, and the overall working efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of data governance, in particular to a method, device, device and storage medium for supplementing metadata description. Background technique [0002] Metadata is data used to describe data. The field description information of metadata refers to the information describing the meaning of fields in the metadata database. This information can assist data users to better understand the data. In the big data platform, sometimes there are cases where metadata field description information is not created due to various reasons, which will cause third parties to be unable to effectively understand the data when using the data, causing troubles. [0003] The existing supplementary metadata fields describe the main schemes, which are basically supplemented manually by relevant developers. Specifically, there are two schemes: 1) Developers modify the metadata description information in the source database thro...
