Method for mapping metadata through data standard and related device

The invention provides a method for mapping metadata through a data standard and a related device, and can be applied to the field of big data or finance. When standard mapping needs to be carried out on a target field, a to-be-mapped data standard for the target field is generated, metadata information of each field stored in a campus business database is pulled from a metadata management system, and metadata information related to the to-be-mapped data standard is screened to obtain candidate metadata information; according to a standard Chinese name and a standard English name contained in the to-be-mapped data standard and a metadata Chinese name and a metadata English name contained in the candidate metadata information, calculating a matching degree between the to-be-mapped data standard and the candidate metadata information, and according to the matching degree, determining the to-be-mapped data standard according to the matching degree; and obtaining a mapping relationship between the to-be-mapped da
