-Source Concepts are mapped through a [[documentation:​vocabulary:​mappings|mapping]] to Standard Concepts, and these have relationships of various semantic natures to each other. In addition, they have hierarchical relationships to each other and the Classification Concepts, in this case derived from the Vocabularies A, B and C. Hierarchical relationships amongst Classification Concepts generally are only happening between Concepts of the same Vocabulary. ​+Source Concepts are mapped through a [[documentation:​vocabulary:​mapping|mapping]] to Standard Concepts, and these have relationships of various semantic natures to each other.

 All Concepts are stored in the [[documentation:​cdm:​concept|CONCEPT]] table, all relationships in the [[documentation:​cdm:​concept_relationship|CONCEPT_RELATIONSHP]] table and all generation-spanning hierarchical relationships in the [[documentation:​cdm:​concept_ancestor|CONCEPT_ANCESTOR]] table. The latter are only defined between Standard and Classification Concepts, Source Concepts do not participate in this hierarchical tree structure. All Concepts are stored in the [[documentation:​cdm:​concept|CONCEPT]] table, all relationships in the [[documentation:​cdm:​concept_relationship|CONCEPT_RELATIONSHP]] table and all generation-spanning hierarchical relationships in the [[documentation:​cdm:​concept_ancestor|CONCEPT_ANCESTOR]] table.
