Data blood relationship display method, system and device and storage medium

The invention discloses a data consanguinity display method, system and device and a storage medium. The data consanguinity display method comprises the following steps: scanning a DAG configuration directory to obtain a job task; querying an SQL (Structured Query Language) task unit in the job task; analyzing the SQL task unit to obtain first metadata; analyzing the first metadata to obtain second metadata; and according to the second metadata, generating a data blood relationship graph and displaying the data blood relationship graph. According to the method, the SQL task unit in the job task is acquired in real time by scanning the DAG configuration directory, and automatic analysis and metadata acquisition of a new task are realized; the data consanguinity graph is generated through the second metadata and displayed, rapid positioning and checking of problem data in the data link are achieved, the data repairing efficiency is improved, and the method and device can be widely applied to the technical field
