-The Standardized Vocabularies are organized into Domains and Vocabularies. Domains refer to the nature ​of type of a clinical entity, which also defines the CDM data table where a data record is stored, while Vocabularies are sets of Concepts imported from external national or international existing ​standards, or created by the Standardized Vocabularies Team if no suitable standard is available.+The Standardized Vocabularies are organized into Domains and Vocabularies.

 **Note:** There is no one-to-one relationship between Domains and Vocabularies. Some Vocabularies are very broad, such as SNOMED or Read, and contain Concepts of all medical Domains. Other vocabularies are specific for a certain Domain, such as RxNorm for Drugs or ICD9Proc for Procedures. In many cases Vocabularies are generally assumed in the community to be of a single Domain, when in fact they are not. For example, CPT4 and HCPCS are expected by their name to contain Procedure codes only, but in reality contain Observation,​ Condition, Device and Drug Concepts. **Note:** There is no one-to-one relationship between Domains and Vocabularies.
