Identifier-based data tracing method and device and storage medium

The invention discloses an identifier-based data tracing method and device and a storage medium. According to the method, firstly, metadata information of data is stored in a resource identification information table, and resource identification serves as a primary key of the resource identification information table; then creating an identifier as a primary key of the data, wherein the identifier is formed by splicing a resource identifier and associated data; the associated data in the source data identifier and the associated data in the destination data identifier have the characteristic of mutual derivation; creating an association relationship between the source data resource identifier and the target data resource identifier; and finally, data tracing is carried out according to the identifier. According to the method, the accuracy of data traceability is effectively improved, the storage requirement of the annotation information is obviously reduced, and meanwhile, the traceability query efficiency is
