83 results about "Consanguinity" patented technology

Consanguinity ("blood relation", from the Latin consanguinitas) is the property of being from the same kinship as another person. In that aspect, consanguinity is the quality of being descended from the same ancestor as another person.

Method and device for determining data consanguinity based on structural data

The present invention provides a method and device for determining data consanguinity based on structural data. The method comprises: parsing a selection statement to obtain a source abstract syntax tree, and organizing the table information and the field information obtained by traversing the source abstract syntax tree into a source list layer by layer; obtaining the target abstract syntax treeby parsing the insertion statement, and organizing the table information and the field information obtained by traversing the target abstract syntax tree into the target list layer by layer; traversing the source manifest to obtain the source table information and traversing the target manifest to obtain the target table information to obtain the table granularity data kinship relationship; extracting the target field information for the target table from the target manifest, starting from the first layer of the source manifest, finding the source field in the source table with the same name as the target field information of the target table layer by layer, and when the source table to which the source field belongs no longer comes from the subquery, determining the corresponding source field to be the source field with blood relationship corresponding to the target field information.
